A group of four went through the 8 tubes I am sending to Schiit. 6sn7 or equivalent.
top four choices, (the tubes they liked the most and the order)

Ken-Rad VT 231 black glass
Cbs/Hytron 5692
Melz 1578
RCA grey glass 1942

It is early, I have more people who will do a listen so with a larger group the order could change a lot before I am done. There will be a pretty solid contingent who are into classical music and that could really vary the outcome.

Interesting. Were you using the Vali 2? If so, it just goes to show how far the synergy thing goes. I really liked the CBS/Hytron in the Vali 2. I mean really liked it, although I've only rolled a few tubes through it so far. Pulled it out and stuck it in the Lyr 3, and zzzzzzzzz. That 5692 and the Lyr 3 just don't like each other. Don't know why, but that same exact tube that wowed me in the Vali is bloated and lifeless in the Lyr.

TK has a 752. Not sure if he actually uses it. And as soon as you can snatch the pebble from my hand, you'll have one too. That or a new shorts control, whichever comes first. LOL!

Use it on every tube I sell, just without any electricity.

Only newbies think they have to plug it in.

They were in an amp I built for the purpose. I have the same issues with the BH crack compared to the Vali 2, I also wanted something with dual volume controls so each channel could be adjusted just a bit.

I've managed to accumulate 3 out of 4 and if you cut me some slack and allow 1945 vs 1942 RCA Gray Glass, I'd have all 4.

And you have the Foton ribbed plate and Frankie, also in the final four is a Tung Sol Mouse Ear that I really like. That just leaves the Sylvania Bad Boy and I am sure you have that one.

It came in 5th but the voting was very close between four and five. Using a 100 point system similar to what was used on DAC’s, same music and criteria.

 

[Ripper2860]

Yep. I have them all except the Tung Sol mouse-ear. I must get around to snagging one of those.

 

[Paladin79]

Later tests will have Mullard and Brimar and a friend promised to sneak in one tube that dreams are made of. I am fashioning a cage that can be flipped down over pricey tubes so they do not have to be encased in pvc for those tests.

….a friend promised to sneak in one tube that dreams are made of.

I thought I was the only one here with 300B's.

I have one I bought from Brent Jesse. Nicely matched triodes that both hover on the minimum good line. It sounds minimum good too, but I assume that's because it tests minimum good.

 

[Ripper2860]

So what exactly is min. acceptable for 6SN7 on a Triplett 3444?

That guy is a great seller!






Possibly several years ago, but definitely not now, the Lyr tube rolling thread has some unhappy campers who bought tubes recently. Including me.

This is a 6sn7 equivalent and once again there is a wager involved. There are supposed to be a handful in existence and he has two. I have an inkling what they are only because I know who his dad and grandfather were.

 

[Ripper2860]

There are supposed to be a handful in existence and he has two

I'm gonna go out on a limb and say they are 2 of the 5 or 6 rare 'Good Sounding' GE's that were part of a bad production run. Most were destroyed once the error was discovered, but a handful made it out of the GE plant and into the hands of collectors.
