I have found that using pinch waist Apmperex E180CC in the 1st position, Telefunken ECC803s in the 2nd, and Telefunken 12AV7 in 3rd, sounds best in my system. I have the 5 star's, but felt them too thin, with the berning. I liked them with Exemplar, but feel the PW amperex is best over all. I have some more PW on the way, and will play with adding more into the system. JMO, YMMV.
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.
