The specific gear is the AMR DAP 777...

Rocket Logo 6H23's from Upscale Audio.
They are not expensive, but they should sound similar, if not better, to old production Siemens, which seems to be the type of sound you are leaning towards.
I've owned/used pretty much every old production 6922 type, though in preamp gain stages/not CD player output stages and that's what I would start with.
...they only have driver grade in the tube available at Upscale.

Ask them.
Thanks, I will, but I doubt it, since Kevin doesn't recommend driver grade for DACs and/or CDs players in the other 6922s.

Thank you... Will definitely check into them..

If you contact Upscale, you might want to ask their opinion of the Type 3 in terms of your application and for what you're looking for sonically.
Although I've never used them in a DAC, I've been very pleasantly surprised by how good these sound in my preamp. And for $35 each in Platinum grade, your financial exposure isn't very large.

These tubes will be used in the amplification of the preamp within the AMR DAP... the stock ones are a Russian 6922 type that they have put through a some kind of baking process. It's NOS 6N11 high-speed valve tube. They do sound excellent... and those who have upgraded to the vintage 6922s have said that when doing a comparison. So, I suspect, what one is looking for is that extra push into detail, dimension, etc.
AMR suggested either the Mullard 6922s or CCas. Thorsten Loesch who designed it referred me to the references 6922s, etc that Joe put together for us on AA. My hunch is that I am looking for cream on the coffee :)
According to AMR, it will take ECC88, E88CC, 7308, Cca, 6DJ8, 6922, 6H23n-EV optional

Okay, I better understand what you're trying to do. The Siemens 6922 and CCa from the 60's are excellent tubes. They tick all the audiophile approved boxes of resolution, an even frequency response and throw a really good soundstage.
I have a mixed set of 4 Siemens 6922 CCa and a pair of Siemens 6922s in my preamp currently and they are really excellent. Everyone's taste is different, however, and I always ultimately find them a little soul-less, for lack of a better way of putting it. But that's just to me, naturally.
My sonic biases always seem to lead me back to Lorenz, Amperex and Telefunken.
Hope you find the right ones for you.
Joe
Have you heard much difference between the Siemens 6922 and the CCa's?
Yes, I wish there was a tube library similar to the Cable Co, where you could say send me a pair of Seimens, Amperex and Telefunken.. and I will let you know which ones I would like to order :) That would be awesome... especially at the going prices.
Another member, really likes the Telefunken E1888CC, then the vintage Siemenens... but you're talking equivalent CCa prices or more. Or the Amperex 6922 PQ, pinched.
I particularly want to avoid a tube that warms or clouds the system. My preamp which was custom modified uses 27s... so there's a lot of soul going on. Thanks for your input... really appreciate it.

Unfortunately, as helpful as some kind of lending library like the Cable Company has except for tubes would be, it's just not practical.My c-j Premier 16LS2 preamp runs on three tubes per channel and I've never heard the Siemens CCa and 6922s separately so I can't really comment on how different they sound. The preamp is designed to basically combine the tubes for each channel into one composite triode.
If I had to guess, and it's just that, I'd say that similar vintages of both sound pretty much the same. The CCa's are supposed to be selected for low noise, but I don't know if that in reality translates into a quieter and more resolving sound. Maybe, maybe not.
I do have a pinched waist Amperex 6922 I've used as the input tube for my Premier 140 amp and IMO that is a very special tube in that application. They're also very expensive.
I have and like TFK 6DJ8s and 7DJ8s. They're just a small amount less resolving in my opinion than the Siemens 6922s and with just a touch more warmth and musicality. My taste runs toward a slightly warmer sound and that's why I really like the Amperex house sound, as well.
The most neutral tube I've heard that seems to combine the resolution of the Siemens with just that touch of TFK warmth is the 60's vintage Lorenz 7DJ8. I've never heard the 6DJ8 variant but in my limited experience and in my preamp, the 6DJ8s and 7DJ8s of the same vintage sound basically the same to me.
The Lorenz 6DJ8 family members from that time period seem to be really difficult to find, however.
Hope this helps some.

I basically don't want the tube to alter the tone of my system which is highly musical and engaging... just open it up more... give the playback more dimension, detail and air... but not to color it - if I am making myself clear. Otherwords, I'm not looking for a tube that would bring additional warmth to what I already have.
But, that's always hard to second guess... because so much is determined by the synergy of all the parts.

It does help, Joe... You/ve been very generous with your experience and knowledge... And it very appreciated.
