Hi all,
My Jadis JA80's are getting noisy and need retubing, and I'm torn between KT 88's (possibly the Psvane KT88-TII) or KT120's.
I don't want to lose any of of the beguiling musicality that I bought the Jadis's for, but I'd like a quieter, blacker background and tighter bass. Is the KT120 an all-round improvement or will I be risking "throwing the baby out with the bath water"?

Would love to hear your opinions!
Thanks, Mick

My good friend has JA80s and I thought the KT120s were a huge step up.

Quoted from the from the Jadis JA120 datasheet:


Jadis has adopted the KT120 valve, which will increase the power, reliability, the dynamic range and every other parameter of this milestone amplifier.Jadis has recognised that the brand-new KT120 expands on all of the virtues of the much loved KT88/6550 workhorses that have powered so many top-flight amplifiers. With their acceptance by Jadis, the doyen of French high-end amplifier manufacturers, the KT120 has found a home that is the audio equivalent of a well-appointed chateau: stylish, timeless, immune to fashion, elegant, regal.

What speakers do you have? If you don't need the extra power, I'd tube roll KT88s. I like the Valve Art cryo'd chinese tubes sold on ebay by tubeman. Black Treasures very good too, but may be a bit much with Jadis.

kt-88 is a warmer, richer sound.
kt-120 is more dynamic, faster, punchier sound.
try some EAT kt-88, much more expensive than tung-sol kt-120, but probably much better too.
