Hi, My question is for eany one who may be of help, can this lightspeed atenuator work with a krell class A 700cx amp that is 3.3 volts input sensativity, and 100kohms????, thanks guys! |
@ clio09, Hi, I am currently useing a Ayon cd-2s digital player, It is 300 oms out-put, and the out-put voltage is switchable 2.5 low to 5 volts on high,, I keep it on 2.5 volts to run directly to the krell 700cx, the krell is 3.3 volts in-put.,, The Ayon has 3 R-core transformers inside of it, one for each channel after the signal leaves the out-put tubes, and the other R-core transformer is for the digital.,, thankyou. |
Thankyou gentleman!, The main reason I am interested in the Lightspeed is running the Ayon direct versus having a pre-amp sounds to forward for my tast!, most people do not have this problem with the ayon 2s with a pre-amp!, To me, running the Ayon 2s exploits the true nature of this player, And I have to say, I hate a forward sound!, I was thinking that the Lightspeed would act like some sort of buffer to rid the forward sound, now, thats if the Lightspeed itself is not forward sounding!, where do I buy the Lightspeed?, How does it compete to the tvc?, witch do you guys think has the better sound?,, Thankyou, cheers! |
@ clio09, Thankyou, you are a gentleman!,You also proved to be a great asset here for me, I will take a look at the threads you posted here,again, Thankyou so much! |
@ clio09, I have not told you, my amp only has balanced and Krell cast inputs,no rca single ended inputs!, can George make a lightspeed with balanced connections?,The praise here on this product is worth while to buy and try!, To use it I have to have balanced connections, I see this thread started in 2010, and George might now 2013 have available balanced???,,Whats your advise?,, cheers! |
@ Georgelofi, Hi, This is a nice supprise!, You are the owner and Designer of the lightspeed Attenuator?, Clio09 was talking about interconnects low capacitance,, I have the Taralabs zero Gold Interconnect,To my knowledge, This cable has one of the lowest capacitance rattings in the industry!, please look at the specification sheet thats available on the Taralabs internet site, then, If you would, please give me your opinion,this interconnect cost so much money, the only option I can think of to be able to use the Lightspeed mk2 is to buy gold plated xlr to rca adapters!,reterminating this i/c is not feasable!, It would cost more to do that than the entire lightspeed mk2 cost???, my interconnect is one meter long too!, by useing xlr to rca adapters,I suppose I would loose a little performance of the cable, maybe 10%???., Is this unit you have here solid state?,and where does the soundstage set?,a few feet in front of the speakers, in between the speakers, or front and center a roll on the soundstage,what roll of seating would you describe the soundstage to be at, a,d,g???,Is the unit warm sounding,analitical on the treble,big sounding soundstage, small soundstage???,you get the picture, I would like you to be honest and describe the sound attributes of the lightspeed mk2.,I have been thru 3 digital players in 14 months, only one player sounded fantastic!, but the unit was bleading d/c from the tubes into my Krell 700cx amp, and that caused it to shutdown to standby, I had to get a refund on that new player, and the second one sounded like crap period!, I sold that one, then the third one that I do still have sounds fairly good, but the soundstage is to forward for my liking running direct to amp!,I may can resonance tune the forward sound out of it??,I have not obtained the cones of my choice yet that will actually work for tunning.,The digital unit I have uses 6h30 tubes that I really do not like!,The 12ax7 tubes have a better sound stage to me, that was in my first digital player that bleed d/c, I hated to part with the unit,I had too!,, Thankyou!,All of you chime in if you would,Thankyou to all you gentleman here, you guys are very considerate here!, cheers! |
Oh!,I almost forgot!,I am sorry,What is the Gain specification ratting on the Lightspeed mk2?,thankyou, cheers! |
@ Georgelofi, I am sorry, I did not mean for you to work for it!, I have been thru so much heart ache over audio the last 13 months!, regardless of cost of eany unit, I am tired!, It seems like nothing is what its said to be!, I hope you understand my point of veiw here,Thankyou for all the post from you, I will most likly buy from you,I have to waite till my amp comes back from Krell, I have to pay them first, then I will get in touch with you, Do not worry, you got the sale, Its just I have to give Krell 2 or 3 thousand dollars for what they are doing to my amp!BTW, My Ayon 2s is running directly to my amp!, It has a high quality digital volume control!, Like I said, A r-core transformer for each channel after the signal leaves the out-put tubes, and the third R-core transformer is for the digital domain, Thankyou, cheers! |
@ clio09, I agree, the adapters, and try the lightspeed!, You have been great here!, A true asset to us all!, Thankyou so much for your time, It will be some time before I buy the unit, As the post above tells why, regarless, I will be buying the Lightspeed!,, cheers! |
@ Georgelofi, Hi, believe it or not, I have used the Ayon 2s volume control at the level you are speaking of plenty of times!, It just dont have the gain for me to get the power out of my amp that I would like to have, I would say, half the power of the amp is available, no matter the max volume I set!, I have the Krell fpb 700 cx amp, I have 6 oms speakers that ride mostly at 4 1/2 oms while playing music, still, I know what high power sounds like, since I was a life long musician!, and the speakers are 91 db sensativity!, I do not like most pre-amps out there because they add a veil over the music at hand, and they always add their sound signature to the sound as well!, then theres the cost of mutiple cables, which btw, my i/c retails for $14,950.00 a meter!, one of these is what I like to stick with considering the cost here!, I still want to buy your unit, I can always use it somewhere on the other systems I am building over the next few years, by having your unit already is a plus with doing this!,, cheers! |
Hi Geogelofi, You are correct, I only use the ayon 2s player on 2.5 volts, that way I will never clip the Krell balanced input!, As far as the amp goes, I have never, ever heard this amp clip!, Yes, I do have the Ayon set on xlr setting, o degrees on the phase setting, I have played with all the settings, To my amazement, they work to very good effect!, George, The Krell was damaged when I first moved into this house I am renting 13 months ago,The receptical had 220 on it, It blew my amp up!, I sent it back to the dealer that sold me the unit used, As good as their technicians were, The compexity of a $14,000.00 amp new was beyound their experience!, I had problems with the amps bias on the left channel, It got worse as time went by, to the point that the amp was getting so hot on the left channel, that it would shut its self to stand-by!, so, my lesson learned here is to never let any body work on a Krell amp that is this sophisticated as this Krell 700cx is!, the dealer was not a Krell dealer at all!, I know of only two places here in the u.s.a. that can work on this amp to great effect is the krell factory, and the company called, the service department home, steve is the owner of the service department home, He was the service manager there at krell for 20 years before he started his own company in 2009, he is also a certified service bussiness for Ayon audio!, He told me on the phone that the Ayon 2s is really a hybred player, since the signal leaves the out-put tubes and then goes to R-core transformers that is on each channel that their is no way ever that the Ayon 2s would propose a problem for the krell 700cx running direct to amp, the transformers is the buffers for eany and all d/c that may or may not come from the tubes!, so no, the Ayon 2s was never the problem!, the problem of the krell 700cx was prior to me buying the ayon player!, the dealer who attemted to fix the unit basically band-aided the amp up to finish the sell to me!, I cannot complain alot here, they attempted to fix it for free!, At the end of the day, they had no bussiness tring to fix the amp!, they should of sent it to Krell as I did!, and since the amp is there at Krell, I am requesting for the amp to be totally renewed rather it needed it or not, that way, there will be no worrys in the next 25 years!,, cheers! |
@ Georgelofi, Hi, The Ayon 2s sounds better on the 2.5 volt setting for some odd unexplained reason!, Like I said, I have played around with the toggle switches on the back of the player for days on in!,I also do not believe turning my system up to loud volumes on the 5 volt setting is very smart to do, considering the balanced input on the Krell is 3.3 volts or so!, This will not do nothing to the amp it can not take, my speakers, I wish not to damage those!, A 3 1/2 volt didgital player would be perfect!, LOL!,,, I do appreciate your time to talk to me here, It is very special when a componet designer takes time like this out of their busy life!,, Gratitudes to you!! |
Thankyou Georgelofi, I know what you mean now, you are saying if I use The Ayon 2s on 5 volts out-put, and use the volume control, I would never turn it up to 5 volts, most likly the amp would be driven to full signal when the volume pushes the signal to 3.5 volts!, most likly 1 o'clock on the volume control?,, cheers! |
Hi Georgelofi, I believe the thread cd player direct or preamp that is new, needs your help., you can answer better than I can, so I did not post |
You found it, very well done, thankyou. |
Hi Georgelofi, come on over to the cable thread,Taralabs 0.8 versus the one, there you will find a member friend of mine that is interested in your product, His name is waxwaves, read the last few post, if you could agree with my findings and back me up concerning all that I said about active pre-amps versus source direct to amps, and addresse waxwaves about your product, I would be grateful, thankyou George. |
What do you mean by your post Ebm? |
Georgelofi, It would be an honor for you to come to the thread I requested, there is a need there for your vast exsperience, comment on all subjects, as you can see, this thread is unlike most others, we talk about all audio, not just the subject of the thread, please. |
@ Georgelofi, Wow!, My interconnect, The Taralabs Zero Gold's capacitance is 4 pf per-foot!, then the new Taralabs Evolution Grand master interconnect is 2pf capacitance per-foot, I'm good with the capacitance specs then!, thankyou for your reply Georgelofi. |
does anyone have any idea what the view count is for this thread? |
|
Hi Georgelofi, is it possible to use a light speed attenuator on a phono pre-amp?, I like being different and the first world wide to have such a scheme, if not, can you build me such an attenuator? |
Hi Georgelofi, thankyou, the phono stage that I'm considering is the Vincent pho-700 with outboard power supply solid state/tube hybrid mc/mm phono pre-amp, check it out for me George, audio advisor sells it, has the specifications on their site. |
George, the specs are mm 47k, mc 100 ohms, 12au7 vacuum tube used in duel triode mode, thankyou 😀 |
Hi Georgelofi, I talked to Joe there at audio advisor, he said that the Vincent pho 700 does 8 volts max out put, your unit is passive?, I may put this on my modified krell 700cx to play with from time to time, it's 100kohms, however, it takes 3.35 volts to push, as you know, I've been pushing that amp with 2 volts running directly from the digital player, cheers |
