Hi,
I fancy trying some KT88, KT120 or KT150's in my power amp. I need 8 of either in total.
Just bought it and here I am wanting to upgrade it already

I'd concur with that, for all an amp may be made with flexible voltage settings, the output transformers will have been made for one set of valve characteristics in particular and that's likely to deliver an amp's sweet spot. That was my findings with the Leben 660p anyway - yes you could use other tubes but anything different to EL34/KT77 types gave no benefit.
EDIT - Having said that I did try about six different tube types so totally understand the urge to experiment!

Fair enough, the reviews and videos on YouTube say to try all the models I've mentioned as they all give different characteristics or improvements as well as different power ratings. One of the main reasons I chose this amp was the ability to swap valves and let the electronics inside do all the biasing and adjustment.
Well worth checking out Kevin Deals videos on YouTube for a better description that I'm giving

I must admit I would be keen to experiment with other valves - el34 have never succeeded in making the music really come alive for me, to my humble ears there's something fundamentally dynamically drab about their presentation however "sweet" their midrange may (or may not) be tonally, and I've tried a few implementations.
I'm happy to acknowledge that others feel different about them, though. (Although I remain baffled by the fact )
If I read aright Mike's musical tastes I'd suggest KT90 be added to his 'must try' list .. the ballsiest valve amp I ever had was fitted out with 2 KT90 a side. I've not heard 120 or 150, though.

I wouldn't be messing about with second owner valves, maybe for a pre but not 8 for a power amp. Recipe for grief.
