Tube rings for power tubes?
Be sure to try them both with, and without the rings. I found that the life got sucked out of the music with rings on my EL34's.Herbie's are probably the best out there for tube dampers that don't kill the music, at least on small tubes.Enjoy,Bob 
Passive preamps: What are the relevant numbers?
The McCormack amps have a very high input sensitivity. Basically because they were designed to work with Steve's TLC preamp ... which is passive. As long as your CD player has an output level that is close to the industry stardard (or above it), a... 
Your top ten CD transport???
Or something that stacks up for those of us on a more modest budget ...... the Empiracle Audio modded Sony 7700 DVD player. It consistently competes in the top end with those transports that run into the stratosphere.Enjoy,Bob 
What is very good imaging and soundstage exactly.
Sounds about right. Do you have any room treatments ... especially right and left of your speakers at the 1st reflection points? That would help with the width of the image.Enjoy,Bob 
Any opinions on retubeing W/winged c or mullard re
I have read and heard many non-flattering things about the Mullard reissues. I had a pair of Electro Harmonix EL34's and another pair of 6CA7's. They were both OK, but not ideal. I pondered the SED's, but wound up buying a quad set of JJ/Tesla E34... 
Who has Caps on their AC lines ???
I've implemented the Auricap tweak in several DIY mods to digital players and DAC's. In each case I've always put them AFTER the fuse, just in case there is a blow out. You really don't want a short, no matter how well the caps are rated. It could... 
If you haven't tried them, you need to...
Funny, but not all HDCD's are actually labelled that way. Nothing on the box or the disk for Cassandra Wilson's Rendezvous CD, but it plays as HDCD in the player.Enjoy,Bob 
panny 60u vs. 600u
I'm also looking at the 60U. The price is right (@$1300 at some online vendors with good ratings).Is it still a wise decision to also purchase the after market warantees when buying a plasma? Do the newer plasma's still suffer from issues that wil... 
In the market for a plasma.........suggestions?
That's a great suggestion Rysa4. It's not just a matter of finding the best price. Problems definitely DO happen, and enough of us have been burned by needing to return a defective unit before (e.g. claims that it was never received back, rediculo... 
In the market for a plasma.........suggestions?
Is it still a wise decision to also purchase the after market warantees when buying a plasma? Do the newer plasma's still suffer from issues that will need warantee work within 2 years?I'm also interested in the Panny TH-42PX60U, and see great pri... 
Best Phono Preamp for budget system
Ha, ha, ha, ha ... "which one". That's another thread. Search the archives for too many options.But I would suggest adding the Hagerman Coronet to your list of phono stages if you plan on staying with high output cartridges (MM or MC).Enjoy,Bob 
Home Depot Ext. Cord for Speaker Cable
I use it for my outdoor speakers. It is waterproof and works fine there. I just snip the third wire at each end and ignore it.But I wouldn't think of using it inside, not when there's relatively inexpensive alternatives that make sense. Like Spelt... 
Has anyone heard the Burwen Bobcat system
Also, when Levinson was asked to play some before and afer comparisons to justify to all of us that what he was SAYING could be proven, he refused to comply. Some lame assed excuse about this not being a test, but rather a demonstration.More like ... 
Mods in Tube players: list in order
From my experience I would say the following order applies to most any mod, not just CD players:(1) clock, although a very expensive mod, it has the potential to make the most improvement in CD players(2) power supply, especially for switching typ... 
ANTI-CABLES by Paul Speltz: Anyone Using Them?
I just picked up a set of the Speltz IC's. Compared them to a DIY set of Jon Risch 89259/89248 twisted pair (unshielded). They didn't come close in the mids and top end.However, I am using them to feed signal to my bass amp, which was too loud for...
