I am also using the Tung Sol 12AT7's I like the sound of them very much. I tried some Telefunkens, but did not think they were any better than the Tung Sols and they cost more money.
Berning ZH270 Input Tubes
Has anyone out there that owns a Berning ZH270 power amp compared the sound of the GE 5965 5 star tubes with the Amprerex 7062's? I have been using the 5 star tubes and I just bought a pair of the 7062's. To my ears the 7062's have a very good top end with a slightly more recessed midrange (giving a sense of more depth). They seem to give a very 3 dimensional effect, but the bass seems to be softer with a warmer sound (not the bass impact of the 5 star). Can anyone give me their impressions.
