Soundermn, my experience echoes yours except I haven't sprung for the big ticket KT150s.. KT120s made my PrimaLuna amp sound transitory and I've been running the TS 7581As for many months....I like them even more than the GoldLion KT77s, which are outstanding but a little analytical for my taste.
Tell us about your KT150 experience
By now, there must be quite a few folks who own amps that utilize the Tungsol KT150 tube. ( I own a pair that do).
As such, i would like to hear the experiences that you folks have with re-tubing the amp with new KT150’s...what dealer did you buy from, how well were the tubes matched, how long have they lasted, any problems with the tube...new set or old set? What amp(s) are you using them in?...and lastly do you believe that they are superior to other Pentode power tubes...and why.
