RE: Tube dampers etc.

Posted by Lew on April 11, 2016 at 10:34:41:
I absolutely agree that the quietest tubes are not necessarily the best sounding. (In fact, it would not be incorrect to say they are USUALLY not the best sounding.) Like I did say, I have stuck with the KenRads in the MP1 only because they are my favorites in terms of sound quality, but they have never been the quietest. They were somewhat microphonic from the get-go. And yes, a little microphony can be euphonic, but we as audiophiles are not supposed to admit we like that effect. (Joking.) Anyway, one KenRad has definitely got to go; the other may still be usable.

With me, it's a trade-off. I select first for sonics and then hope the tube is quiet enough to tolerate in the circuit. All I meant to add in the first place was the idea that noisy tubes in gain stages will be more evident than when the same tubes are used in stages that do not add gain, as driver/cathode follower and probably as CCS.
