Best 6922 tubes for DAC

Anything by Phillips (e.g. Amperex, Mulllard) will be a huge improvement over Sovtek. I'd recommend Amperex Bugle Boys or maybe 7308s for the ultimate upgrade.

This has been an invaluable source in my quest for 6922/7308 tubes. It's called Joe's Tube Lore, and it's quite thorough. Although just one man's opinion, I've found the comments to be spot on when I've tried different 6922 and 7308 tubes.

I am using Philips Miniwatt 'SQ' in my 24MXL- very full-bodied across the spectrum, perhaps ever so slightly less detailed than the Siemens, but more full-bodied bass IMO, and a wonderful midrange...

I agree with Sutts about the Philips "SQ". The Amperex 6922 & 7308 fall between the Siemens 7308 and Philips SQ on the detail spectrum...the Siemens being the most detailed of the bunch, IMO.

I recently upgraded my amplifier's input tubes from Sovtek 6922's to EH 6922's. They are very similar, with better bass response coming from the EH tubes. You might give these some consideration, at $20 each new with gold pins. Don't go down the NOS road unless you've got so much money that you've forgotten what One's and Five's look like, and you'd better have reliable sources, because (IMHO) many of the NOS tubes circulating through cyberspace right now are actually OOS tubes (Old Old Stock) or just plain OJ (Old Junk).

Cheers and Good Luck
