After 18 months with the Inspire gear I've found a few power tubes
I really like. However, like you none that I have tried are awful. All of our systems and sonic preferences are different. I don't think there is a silver bullet power tube.
Chinese NOS that is almost hard to believe. 
Like Peter, I find that the new production power tube are really excellent and you can experiment w/o breaking the bank. |
Agreed (except for the TungSol 6AR6WA). Have you ever tried the 807 or KT-150? Is there a better 6550 out there (current production) than the Valve Art? These amps are so versatile and sound so good, there seems to be no limits to the range of sound tweaks at our disposal (except for the $$$
). Curiously, my empirical assumption of a correllation with Triode plate current specs in the (top 50's to 80+) mA range has met a contradiction in the 350B (56 mA) and the 6550 (150 mA). The former should have worked and the latter not, but it turned out quite the opposite. Evidently there's more to the plate current to make the amp sing, maybe the tube design/construction as it relates to the rest of the system ... Hard to predict! If I were a reasonable dude, I would stick to the KT-66z and KT-77 coupled with the 274B and 5AR4, and CV-181 TII and CV-181 black glass, respectively, as these seem to be the best of them all (in my system, that is). But ... I wouldn't have gotten to this SQ level without trying.
