Thiel Owners

Thank You Prof 
Your in-depth evaluation is fantastic, Its to bad the the " professional "
evaluators couldn't be as precise as you.
You've help me get over the regret of not moving up to the 3.7s
I purchased one of the last CS2.7 pairs available from Thiel,
I had to purchase the speaker spikes used on the 2.4SEs and 3.7s
in order to penetrate the carpet.
I love the sound and the looks and they aren't so heavy that I'd need help to move them.

Thank You jafant

Nice of you to ask , nothing as lofty  as what is sold on Audiogon.
Thiel CS2.7 ( only because I got them for less than 1/2 price New ! )
McCormack DNA-250 ( Conrad Johnson )
Gold Point passive preamp
Carver SD/A-490t CD player
( only because there is some music not available on Vinyl )
Sim Audio Moon LP110 phono preamp thru a regulated power supply
Merrill Heirloom TT with an upgraded RB300 tonearm
and a Grado Sonata Reference cartridge.
all thru Cardas Neutral Reference interconnects and speaker cables,
and arriving any day now a TT speed control from Mr. Merrill,
so I can finally play my favorite album 
David Crosby    If I Could Only Remember My Name
a 4 sided copy at 45rpm that I've had for over a year now.

the future upgrades planned
Tube phono preamp, Decware I think
Origin Live Illustrious Tonearm
and Soundsmith Aida or the Voice or maybe another Grado The Statement ?
Used /Demos most likely due to their prices.

As a true Audiophile or want to be , always looking to upgrade.

Since the 2.7 has the same woofer as the 2.4
is it possible to upgrade the capacitors to the ones used in the
2.4SE ?
Has anybody tried ? 
I haven't contacted Rob at Thiel yet to see if it's even possible,
and if it is can I send it to him and keep the warranty.
I am always thinking of ways to upgrade what I have,
not just buying new or different.

Prof
When i decided that I wanted Thiel speakers I was looking at a pair
of 3.6s up in Portland but by the time I ready to rent a van and go and buy them the were gone , so I started to look for used 3.7s
but the prices were still to high for me ( $6,800 plus shipping ! )
so when I saw 3 pairs 2.7s going on E-Bay for $3,000 I didn't exactly jump on them right away , I placed a bid and lost :(  then another  
3 pairs went up for bid , I lost again :( , So I called the seller
Thiel audio and they had 3 more pairs and I bought a pair for $3,000
with first choice of finishes :) ,
on the same morning they listed 1 pair of 3.7s for $7,000 !
I thought about calling them back and buying them but still to rich for me. 
These were all new , Thiel didn't even know they had them until they went into the storage room were they thought the file cabinets had been placed after the move to Tennessee .
the last new genuine Thiels available .
I feel very , very Lucky.
and now very very Happy  :)

I haven't heard back from Rob at Thiel about the crossover capacitors yet .

Rob

Thank You Jafant
Since Prof brought up finish , what finish are your 2.4SE's ?

Prof ,  I had seen them on E-bay just before fathers day 2016,
finish was not my main concern , finding New Original Thiel speakers at less than 40% of their list price was a dream come true for me.
I bought my own a fathers day present.
I had the choice of Maple ( to light/blonde for me ) , Walnut ( it was a beautiful veneer but to brown ) , I chose the light Cherry ( safe pick ? ) nice red tone to them.
What were you looking/waiting for ?
If memory serves me ( reading many pages on the thread ) are your 3.7s the Gibson specials ?

As I am trying to find out if " upgrading " the 2.7s like the 2.4s
were upgraded is possible ,
I was wondering if anybody
has heard both the 2.4s and the 2.4se's ?

My personal opinion is that Thiel missed a marketing opportunity ,
they should have come out with a 2.4se without the 
extra cost veneer and the expensive outriggers ,
and come out with a 2.4 mkII , a little more costly but it would have been all about the sound .
That is why when I see the pictures of the crossovers of the 2.7 and 3.7 
( which look like they used the same components )
verse the 2.4se that if it is possible to " SE " the 2.7s then it would be possible to " SE " the 3.7s !
Something good for us and Thiel IF they wanted to offer the service !

Call me Crazy
Rob

something to a little different listen to  
the Temptations   Psychedelic Shack

jafant
When I talked to Rob ( last year ) at Thiel he had informed me that the veneer on the SE cost $1,000 a sheet !
Thank you for sending the e-mail because I have a feeling the Thiel will not want to get involved.

Prof 
Great finishes , I guess that my memory is getting old,
when I was looking at the prices of 3.7s there was a pair of special
finish by Gibson guitar !
The only ebony speakers that were on e-bay when I bought mine
was 1.7s , I almost bought a pair but because of the bargain price ,
but then another 3 pairs of 2.7s became available
Since I had a pair of black 2 way speakers that were given to me by a a friend and former Thiel 3.5 owner nkonor ( Norb ) about 25 years ago 
and a few upgrades later , I wanted 3 way speakers that weren't black .
As you can see I keep things for a long time 
I think that the 2.7s will be my last pair , unless I win the lotto.
Just finished my Sunday Classical music day.
Now for a little jazz to end the evening .
Rob

First 
I would like to thank jafant for going out of his way to offer his assistance. .

For all the 2.4SE owners , I learned that the crossovers used are more than just larger and higher quality capacitors,
Thiel re-tuned the entire crossover circuit .

For the 3.7 owners something that didn't happen ,
just before Thiel was sold they were working on a 3.7SE !

And for the project that I thought I could do with my 2.7s ,
I have discovered that my desire and enthusiasm were way ahead of my knowledge of the speaker cabinet construction , making the proposed project much more difficult and possibly damaging .
I will not risk removing the woofer .
Not that I'm unhappy with the sound of the speakers.
Oh well , I'll work on my Carver SA/D 490T CD player.

I have used BlueJean Cables and I too ordered the 10 guage speaker wire and used their interconnects, sounded great for a great price.
Then moved up to Cardas Quad Link and now am using Cardas
Neutral Reference with the hope of finding a used pair of Golden Reference some time in the future.

Good Evening All

Prof , it seems like your listening to your 3.7s now ,
are you still going back and forth with the 2.7s ?

Question to all 2.7 and 3.7 owners
Do you hear a pop when turning your amp off ?
This pop sounds like either the tweeter popping back 
or a capacitor in the crossover discharging quickly ,
and it only happens on one speaker.

Reading about the freight cost and willingness to travel long distances to get a pair of speakers was interesting to see how far audiophiles will go
to  acquire a pair of original Thiels .
I was going to rent a van and drive 110 miles to Portland to buy a pair of 3.6s but by the time I decided to do it they were sold,
lucky me because new 2.7s became available less than a1/2 year later,
and the price included delivery !

Just got a new Grado Reference Master 1 cartridge ,
nice upgrade from a Grado Reference Sonata .
Took a long time to adjust everything ,
getting the anti-skating down was time consuming
and couldn't have been done without
the Cardas  frequency sweep & burnin  LP.
Had to set it at 159 grams to keep it neutral in both of the groove-less tracks that are used to test anti-skating .

Rob

Thank You Robinbarbour
I knew I should test that to see if the pop moves to the other speaker,
but moving the 56 lbs off the shelf was a last choice, I thought I'd ask others first.

You want to hear Bass !
Try Sandy Denny's 3:10 to Yuma    or
David Crosby's Cowboy Movie.

Prof
do you sit that close with both sets ( are you moving them in and out
of position ? if so my back hurts thinking about it ) ,
how much do you angle inwards ?
I have just about the perfect 8 foot triangle ( hard to be perfect with sloped speakers ) with about a 10 degree angle inwards .

Rob

Topic

What Song, Album or Genre do you use to set up your speakers ?

I had moved my speakers back just one inch and had to re-angle them.
I tried to have them with as little angle as possible to get the widest soundstage possible, after several toe-ins I thought I had it until 
Classical Sunday , it just didn't come together , I had to angle it in 
1/2 more to get the Orchestra sounding like you are sitting 
ten rows back center.

In a conversation with Prof I learned that he has his speakers 
8 feet apart and listing position 6.5 to 7 feet away with little toe-in.
I have 8 feet apart and 8 feet from listing position ,
I had guessed a toe-in of 10 degrees but after measurements and mathematics it turned out to be 16.5 degrees toe-in .
Using the front of the speaker being the only straight side .

I guess that the difference is in the music that you listen to
as to setting the speakers position.
I listen to 70% rock 60's & early 70's , 10% folk 60's & 70's .
10% jazz 50's & 60"s and 10% classical 50's , 60's & 70's .
 
Something for all Thiel owners to talk about.

Rob

P.S.  I had mentioned 2 songs that exhibit strong bass
        I would like to add an album  
        Jefferson Airplane   Crown Of Creation

oblgny
How far is your listen position ?

The back of my speakers are 21 inches from the front wall,
with the center of the base being 31.5 inches from the side walls,
toe-iin focuses my center stage , it might also be the side wall reflections that have a lot to do with it.

Prof

I found Everything But the Girl ( on allmusic.com ) ,  Amplified Heart ?
Since you like EBTG then I think you would enjoy
Tuck and Patti , I have their greats hits CD, 
their Guitar work and vocals are FANTASTIC, husband and wife team.
I have a CD player only because some music is not available on vinyl,
Cd's are less than 5% of my listening.

Between learning from nkonor and Absolute Sound and getting to a point where the system is good enough the hear the differences 
I've discovered room acoustics are just as important and any component, from the AC power to your equipment , from the cartridge
( or CD player ) to the speakers.

Hi nkonor , jafant

Happy Friday
Audiophile On

Rob

Wow oblgny
You have one of the toughest roughest rooms to set up
that can be imagined .
At 12 feet distance I can see ( imagine hearing ) why you don't have any toe-in.
My current room is the first I've ever had that is a rectangle
measuring 13'2" wide and 17'2" long with 8 foot ceilings
It would be a perfect size  if my listen chair wasn't up against the foot of my king size bed , that I turned 90 degrees to gain 4" of listening space.
At least I don't have to worry about rear wall reflections.

I agree with you about the air , I could never listen to headphones.

You brought up the Temptations " Ball of Confusion ",
it's been a long time since I've heard that one, 
I've just bought a german copy of   "Psychedelic Shack ".
Something else I've learned with upgrading my system
is the my old records while looking good are worn out,
so I've been buying multiple copies from different countries and pressings of my favorites and play them in rotation.

Rob
 
 

Saffron_ Boots
Warren,
your one of the lucky few that own a 2.4SE model  and it sounds like judging from your measurements you must have a large room.
Have you tried moving them out a little further apart ?
Only the Indigo Girls song is familiar to me , buy coincidence 
I listened to thier second album earlier , it's Friday Folk for me.
I don't have any of the albums by other artist you mentioned.

Arniespin
I thought that the 3.7s came with outriggers as standard equipment,
like the 2.4SEs . Maybe other 3.7 owners can answer that one.
They are something that I would like to have for my 2.7s
but not at the $500 price tag that Thiel is asking.

Happy Friday All and to All Goodnight
Rob

Warren

I have used the Cardas golden rule using the near field formula,
When I got to 8 foot wide
(  as suggested in the Thiel owners manual )
I had the simular problem with the center stage , 
toe-in solved my problem , it took listening to classical music to fine tune it, the speakers are pointing about 16 inches out from each ear.  
Speaker placement and toe-in are personal and a great discussion .
the Prof has his speakers 8 feet apart and sits less than 7 feet away 
and no toe-in,
you have yours 80 inches and sit 100 inches away , toe-in ?

I've tried to get into Rush , a few songs maybe but I just can't.
You have created an interest in Pierre Bensusan after listening to  allmusic's snippets of him, never heard of him before so thanks.

Back to Classical Sunday ,
just finished Beethoven's 1st and 9th by Fritz Reiner & CSO.

Rob

 

Warren

I looked at the pictures of your room ,
It looks like something out of a magazine , beautiful.
The Autograph wall is really something , COOL very COOL .

What is your favorite Rush album ? Do you favor the Mercury pressings over the Anthem ? 
Is there a greatest hits you recommend ?

Happy Friday
Rob

margmike
When Rob ( from Thiel ) e-mailed me about questions regarding
upgrading my 2.7s similar to the upgrade of the 2.4 to a 2.4SE
he informed me that it was more than upgraded capacitors,
they re-engineered the values .

Warren
I've decided that Rush's 2112 will be my one and only Rush album,
it fits more in with ELP and Yes from the time period,
both of whom I saw back in the 70's.

My favorite autographed  was Cat Woman Julie Numar ,
what happened to your system views ?

prof
Finding the sweet spot seems elusive 
even for an experienced listener like you.
I have experienced that listening to one genre of music 
things can sound spot on,
then when listening to another like classical they aren't as focused.
Being kind of slow and lazy it took me over a month before I moved the speakers toe-in 1/4" more in and seemed to have found the spot.
My speakers are now aimed about 16" from each ear.
 I use classical because it is recorded with 2 microphones,
mimicking sitting in the best position during a live concert .
.
I see that toe-in is a large part of speaker conversation ,
no right answer because I think that different music and music that has been recorded at different times and analog vs. digital recording means that there will always be compromise in finding the sweet spot.
but knowing that 1/4" movement can make a large difference makes experimenting easy and free and rewarding.

I agree with you about the looks of the 2.7s ,they are gorgeous 
the 3.7s kinda look like a skinny r2d2.

Warren ans any other Rush fan out there
I went to my local record store The House of Records
( it actually was a house ) looking for a 2112 album and or Gold cd
and found Feedback, Wow fantastic covers by them from 2004, 
they didn't have the others .

Friday and it's raining, good listening weather.
Rob

Prof
I glad to hear you Hugged your Thiels after cheating in them
by listening to the Paradigms.
Have you been able dial in the 2.7's  yet ?

Stevecham
Yes I live in Eugene, moved here from Chicago 12 years ago where
I frequented Reckless Records on N. Broadway .
Where's the other Finest record store ?
I see that you have CS6's , I looked and they are beautiful .
Where in S OR do you reside ?
I am just exploring Rush because Saffron_boots ( Warren ) said he used one of their songs to evaluate speakers,
since I didn't have any Rush It got me motivated to explore and expand my Rock collection which basically stops about the time when
ELP came out with Works and Pink Floyd with Animals .
I saw then both at Soldiers Field Chicago .

zkga
Yes do contact Rob at Thiel , you have 2 options ,
look at images on Goggle , one is the spike used on the 3.7 and 2.4se
the other is the standard spike, if you are going thru carpet
I recommend the ones used on the 3.7s .
I purchased these and used the locking nut from my original 
standard spikes on my 2.7s.
If you don't have locking nuts ask him about that .

Bill 10907
I too use Cardas thru-out, I have the Neutral Reference
interconnects and speaker cables and am very pleased with the sound,
You might want to try the Cardas Hex-link speaker cables
you might also try room treatment first.

While I've been into vinyl for 40 years , cassettes before that ,
I've only been " at it " seriously for the last 10 .
Learned a lot from a friend nkonor but never really applied it until
recently , the kids are grown ( still costing me with education expenses  )
and I have reached an income level that I can spend on my hobby.
Wish I started a few years earlier , vinyl has gone up in price,
but at the same time equipment has improved by leaps and bounds.

For Black Friday I purchased acoustic panels from Acoustimac
to replace my homemade piecemeal setup , waiting for delivery !

Has the talk of the demise of Thiel killed the discussions ?
I have noticed a lot of speakers sale on HiFiShark !
Is this the beginning of the end ?  

Happy Holidays to All and to All a Good Night
Rob

Congratulations Prof

Ever since I read your first post about your impressions of both the 
2.7s and 3.7s I was impressed by your detailed insight,
I felt like I was reading The Absolute Sound magazine.
Which after reading I knew I wanted a Thiel design speaker ,
but also knew it would be years before a used 3.7 would enter my price range , then TAS came out with the 2.7 article which convinced me that the 2.7 was not settling for less other than 2 hz of bass and 60Lbs of weight.
I know you switched back and forth many times before you made your finial decision ( which hurts my back thinking about it ) , so now you can just sit back and enjoy .
And by selling your 3.7s make an upgrade  Thiel owner happy or maybe even make a new convert to Thiel speakers .

I just listened to a new ( used ) Japanese copy of Traffic's Mr. Fantasy and the 2.7s really show their stuff .
I believe that some ( especially me )  2.7 owners hope the Rob Gillum comes up with a crossover board upgrade , since he was involved in the design and building of the 2.7s

Rob

offnon57
I have a CJ made McCormack DNA-250 powering Thiel CS2.7's
and I couldn't be happier , unless I had DNA-750 mono blocks .
While I'm not as amplifier experienced as many of the Thiel speaker 
owners I will say the the 400 watts per channel at 4 ohms 
lets the speakers show how good they are .
Supposedly the DNA-250s have all the upgrades the Steve offers for his manufactured models  .
I have ( so far ) only replaced the IEC connector with a Furutech one,
the 20 amp fuse holder with a military grade 30 amp holder , the 6 fuse holders on the board with solid copper silver plated ones and all the fuses with ceramic fuses ( the main being a Furutech and the rest are Bussman ).
You might want to send it SMC for upgrades or buy another and have mono blocks but the McCormack amplifier to me is fantastic .
Rob

I would like to say to all Thiel owners on this thread
these are the most intelligent conversations I've seen on Audiogon .

For all of you that subscribe to The Absolute Sound
the magazine that gave me the dream to own a pair Thiel speakers.
In the May/June issue page 18  TAS Legacy  Thiel CS5 Loudspeaker,
they tell the world about Rob Gillum and Coherent Source Service and on the opposite page an ad for Cardas Audio the cabling that I use ,
also in this issue page 16 Future TAS my future turntable
 ( when I win the lottery )  by Merrill-Williams R.E.A.L. 101.3 ,
that would replace my Merrill Heirloom .

When I retire this summer I will be looking for the upgrade kit for 
the CS2.7 , I will also be contacting Steve McCormack 
to see if he has any suggestions for upgrading the DNA-250 amp 
and maybe I will upgrade the DAC and a lot of capacitors on my Carver 
SD/A 490 CD player .

Life is good and getting better
Rob

I have a 2003 Subaru that has a  Macintosh  Audio system in it,
I believe that it was  one year only offering ,
sounds great but I wonder if they ran into problems or maybe it was just a promotional deal for both of them .
Subaru was not near as big as Toyota , so maybe the volume allowed for the Macintosh system ?
To bad , maybe Thiel might have been able to survive as the original Thiel company .

The Absolute Sound basically asked the question when having reviewed
both the 3.7 and the 2.7 , is 2hz worth almost twice the price ?
So Tom's point about the difference is academic but
The auditory value of extended bass might not be heard ,
but the feeling  can be quite rewarding  .
 

Question , why are the 2.4 spec'd at 33 hz manuf ( 36hz stereophile )
and the 2.7s are 35hz manuf, when they both have the same woofer and approximately the same size cabinet ?
Crossovers ? why would the newer speakers have less ?

I'm not complaining about the 2.7s lower end
(  especially after moving from 2 way speakers )  
and 'am looking forward to the upgrade possibilities
but I thought I'd ask Why the difference .

Rob

Happy almost Friday

Mr. Thiel
Thank You for the great detail and for giving up so much of your time .

"A factor that contributes to "great bass" is that of articulation which, in a first-order design, includes the low end of the mid-range driver. Jim's 3.7 XO treatment is much more sophisticated and uses better parts than the 2.7 due to budget constraints and designer choices. The 2.7 midrange is fed through a 400uF electrolytic cap, albeit with a PP and styrene bypass in parallel. The 3.7 uses a bank of 75uF polypropylene caps with a styrene bypass. Multiple smaller PP caps provide faster reactions and less distortion than a large electrolytic. "
This explains a lot .

Hopefully when you and Rob  develop an upgrade for the 2.7s
they will based on the 3.7s design with new and higher grade components .
Rob  

Silvanik 
I've been meaning to write and welcome 
a fellow McCormack amp owner and a passive pre-amp user .
You had me daydreaming about the DNA-2 , great specs ,
there was a Deluxe edition for sale on E-bay starting at $2,000 ,
buy then I saw the weight of the unit !
Ironically the Thiel thread was discussing the weight of equipment 
and the aging of the owners , daydream over .

I had just purchased a new phono pre-amp that has taken my system to a new height in listening pleasure .
( luckily because if I hadn't just spent $1,800 I might have still been daydreaming about the DNA-2 amp ) 
I went from an entry level SimAudio Moon 110LP s.s. with a regulated power supply ( big improvement over the stock wall wort ) to
and Tavish Design Asiago tube unit .
New height , width , depth , definition and BASS !
My 2.7s let me hear every improvement every detail with bass that
is so clear and low WOW , no tube roll off here or at the high end either . 

It took me over 2 years to make the decision on which one to move up to 
with  the Manley Chinook , the Decware ZP3 ,
also the Parasound JC jr  and the Sutherland Insight as the contenders .,
but the Tavish Designs with it's separate power supply and all tube MM amplification won out .

Are there any other McCormack amp Thiel speaker guys out there ?
Do any of you use a passive pre-amp ? 
I have seen many of the Thiel owners praise the power of tubes ,
do any of you have a tube phono pre-amp ?

Happy Listening All
Today is Classical Sunday 
Rob

AudioJan 

"Basically, what would you recommend that is similar to the Thiel, but has more dynamics and a bit less sterile."

First I would read the 76 pages of this post ,
since it is was started by a post about the CS2.4SE ,
you might find what others think is the  perfect amp or you might want to upgrade the crossovers to the SE version .

I would suggest trying either a Tube pre-amp or a Tube buffer ,


Rob

Good Morning Dspr

As I see it from reading all the posts
you are the 3rd McCormack amp owner writing on the Thiel owner post ,
welcome from a DNA-250 owner .

Since you are trying to decide which preamp you are going to stay with can I ask what tubes you are using ?
Have you done a lot of tube rolling ?

I just received my Tavish Designs Asiago phono pre-amp going thru a Goldpoint passive preamp and am in listening heaven .  
I have been lucky enough to be able to try
a few different tubes so far and just like any change you make in your system it is amazing how different each tube can sound .
I have found that the Genalex Gold Lion to be my favorite 
and would use them for all my gain stages if they were available ,
so I have to mix in my second favorite Tung-Sol gold pin .
I have tried some older tubes but the problem with them 
are either the prices or the matching/balancing .

I know this tread is about Thiel speakers BUT
with all the input from owners the information about the rest of our systems we can hopefully get the most out of enjoying listening to our Thiel speakers .

Rob

Thank You Tom Thiel
Dis-satisfaction with any component can be the result of
incompatible synergy , your knowledge and insight of the Theil speakers
has at least given owners or future owners some information on what to look for in a power amp .

dsper
I got back into a home audio system about 10 years ago by purchasing 
my dream system from when I first read about it in the 1980's , the  30 year old pre-amp was noisy even after re-capping , so after I purchased a separate phono pre-amp and I started to think about a passive preamp 
with the thought that less is more .  So I now have a 2 input 24 step volume control passive preamp and couldn't be happier with the sonic result , my all tube phono preamp and my CD player with built in buffer tubes are basically plugged into the power amp with just a couple of resistors on the volume control in-between .

You have experimented with a lot with tubes ,  fun but expensive and getting more so everyday , but as you said it's easier and less expensive than changing out components .
I had just replaced the stock 12AU7 with a new Gold Lion the is balanced and cryro treated and am loving it .
I tried an older 1960 RCA gray plate , and a few other tubes that I borrowed to listen to , a Telefunken and a Baldwin. 
I think that I will stick to new tubes 
with the hope that like vinyl more will be available as time goes on.

Happy Friday 
Rob

dsper 

I'd like to thank you for your response about your experience with tubes .
You got me thinking about trying older tubes , 
so after finding and reading about different EF86s 
I decided to try a pair of 1972 NOS Tesla EF806s , the  performance version of the EF68 . 
I still will not take another chance with used tubes and can not begin 
to afford the $300 per tube for NOS Genalex Gold Lions  .
They sound FANTASTIC ,
I am now looking into finding 3 x 5751tubes since new production
is very limited .

You asked how the sound is from a passive pre-amp compares to
powered ones .  Pure , Clean , un-Colored 
Silvanik another McCormack owner with 
a pair of CS3.6s made his own passive pre-amp and loves it .
oblgny ( page 80 ) was disappointed with a passive pre-amp .

I believe ( totally a personal opinion ) that using a passive pre-amp
allows the input to your amp to be the purest sound ,
if you don't like the sound then your input equipment  
should be looked at or thought about ,
not your amps like oblgny was thinking .

Like the Thiel speakers that play the music put into them 
without any coloring , that is how I feel about a passive pre-amp.

Happy Friday 
Rob

oblgny

In my attempt to advise or help another music lover Thiel owner
who is thinking about using a passive pre-amp I have offended you ,
I truly apologize , that was defiantly not my intention .
Please forgive me.

Mr. Thiel

Thank you for the additional information about interconnects ,
I have always tried to keep my interconnects as short as possible,
maybe that is one reason why a passive pre-amp works in my system,
and/or maybe it's because Cardas cables have a low capacitive and inductive resistances . 

Rob

Buggy for me today ever since it was brought up this morning ,
different each time .
It opens and when I try to go to last page " sorry ", then refresh ,
next time it won't open at all - then refresh , next time no problem !
next time it opens but no last page until refresh !!
This time no problem .
Question  is is happening on other forum threads ?



 

I just refreshed the page and  wa la  it appears .

I had purchased only the spikes and not the outrigger support stands
from Coherent Source ,
I used the new spikes with the original locking nuts .
Now the spikes penetrate the carpet
The outrigger stands look great but cost to much for me .

Rob

Prof

It is good to read that your hearing has improved .

When I purchased my 2.7s I was able to pick from the last 3 sets 
available thru Thiel  serial #s 229 & 230 , in Cherry wood veneer .
That same day the last new 3.7s were listed for $7,000 a birds eye maple,  if they were only $6,000  .
The story was that the 3.7s were being kept incase there was a Thiel museum .
The 2.7s were seconds or blems for $3,000 , so I don't think that these were the last produced .
Anyway they had been moved to Tennessee but I had to purchase them thru Rob in Kentucky  .

Wow , I must have missed something censorship ! trolls !
One of the best things about this tread is the intelligence of the conversations and advise ( not like power cords or outlet treads ).

I remembered  a post about 40 pages ago where 
the conversation was about sitting / ear height , at the same time there has been some talk about the importance of  convergence .
Being newly retired and having a boring day I thought I'd try a little experiment , my 2.7 speakers have the 2.4SE spikes so they can penetrate the carpet .
I stared with putting floor disc/savers under the rear spikes raising the rear about 1/2 inch , the sound was like a line from speaker to speaker,
no height or depth and thin on bass.
Removing the discs and raising the rear spikes 
about 1/4 inch the sound was now like an oval and still thin on bass ,
Next at 1/8 inch still an oval with a little more height and depth but like an oval the outside was thin , bass was still on the light side .
With the spikes screwed into the speakers as tight as they could go 
the soundstage now was fully extending to the outside of the speakers ,
the height and depth from floor to ceiling and from front wall to the middle of the speakers .
Point being even an 1/8th of an inch can make a large difference in the listening experience , plus I could do all of this for free ,
not like the tube rolling I've been doing with my phono pre-amp .

Happy Holidays to All and to All a Good Saturday

Thank You T.T.

But I was doing this for shits and giggles ,
before the conversations turned to upgrading / rebuilding crossovers there was a lot of talk about sitting height and the value of time coherence as well as a lot of conversation about speaker toe-in , spikes or no spikes and placement .

I would like to thank you for stating that the 2.7s would benefit from
upgrading components on the crossovers , my project for 2020 
since my 2019 project will be upgrading components in my amplifier ,
capacitors can be expensive .

H.H to All
