I've been through Telefunken (big head, soft bass, brittle highs), Mullard 4004 (good, has some microphonics undisguised in my system), Jan Phillips (nice all around, but thin), Svetlana (bold, with good body, big head, mistimbred), Chinese (surprisingly good, soft bass, rounded attack), Sovtek (ouch), Eletro harmonix (great mids, rolled off), Sylvania Black plate (superb timbre, great attack, solid bass, black background, correct staging, huge depth, slighly forward, extended treble that may sound hard on some tweeters.)
Many ss amps and pre amps can become harsh and bright when driven hard. Non adj. volume Cd players can't. They are always pumping out the same signal.
