Anyone try Pvane tubes in your Dac or CD player?

i tried a pavne tube in an eastern electric i was not a happy camper. i'll stick to nos, such as brimar and mullard, or rca.

i have a vincent cd player. probably different from the op. mine is the cd s6. it takes a 12ax7, a 6dj8(6922) and a 12 au7. strangely enough the best 12au7 for the application was the original stock chinese 12au7. i tried nos tubes, but found them thin, by comparison.

i use a chinese 12au7, mullard gold pin 6922. and tungsram 12ax7
