Do we still need 6550 or KT88 tubes?

I would like to learn your opinion and experience with KT120 tubes.

Considering that KT120 match 6550 or KT88 based amp (is a direct replacement), how do you like the sound of KT120?
Do we still need 6550 or KT88 tubes?
Do we still need to pay for NOS power tubes?

BTW at the moment a KT150 tube is announced. Should be even better than KT120 and could be interesting upgrade for current KT120 owners.

I believe the 6550 and KT88 tubes are still needed even with the Tung Sol KT-120 or now the KT-150 tubes. When I started out with my Jolida JD-502P I initially got the amp because it could handle the KT-120s and there weren't any other manufacturers of the KT-120s. It would keep the tube rolling to the minimum. Well the curiosity got to me and I tried 6550 and KT88 tubes and have found nice differences between each.

Like DonJr said the more the merrier.

Hi Xti16

I contacted leisure-audio about the Shuguang KT-120s and they quoted me a price of $199/quad. I haven't ordered them because I just don't have the funds and honestly am up to my eyeballs in all sorts of KT-88, 6550 and Tung Sol KT-120 tubes. I think I've spent just as much money trying various tubes for my Jolida than what I originally paid for it. Oh well the joys and insanity of tube rolling...
