Hi - I just bought a pair of NOS/NIB 6922 Amperex for my Metronome CDP replacinf the stock russian 6922 tubes. Differences in sound were not subtle, but neither in a win/loss perspective, each has its own strenghts I´m afraid.
The Amperex are more full-bodied, tonally correct and a tad more dynamic than the russian ones, the later had a little more soundstaging and roundness. Me?, I kept the Amperex in the CDP and enjoying music.
Hope this helps
Fernando
PS: Just for the record, I paid 110 bucks for the pair here at Audiogon, great service.
