6922 Tubes!

+ 1 for the National (Matsushita) 7DJ8 tubes from Upscale Audio.

I recently purchased a pair of white label Amperex 7308. While not dead quiet, the noise is minimal (only detectable within inches of the speakers) and not apparent when music is playing. More importantly, they are highly musical. Not cheap, but I only needed two.

Thanks for the suggestion @johnnyb53 , but it took a fair amount of trial and experimentation to settle on a combo that works for me. For TT set-up I'm using the AT150 cart with Audio Horizons TP 8.0 phono pre; and went through quite a few listening sessions with the preamp lid off. That way I could change out tubes in order to do some A/B/A type testing once deciding on a reference point. Were it not for the hassle of finding/packing them up, I'd give those 6N1P's to anyone willing to pay for shipping. As I very often say YMMV.  

I am using Tungsram PCC88 in my Modwright DAC.  It's very musical from top to bottom, great top end, deep bass and gorgeous mid range. You can get platinum grade from Upscale Audio for $50.00.  

FWIW, the Russian equivalent to the 6DJ8/6922 is the 6N23. The 6N1P has the same pinout but is not the same tube.
