Re the subject question,

I have had great success with ""SState pre, into 10watt tube PP power stage driving a resistive load and ReAmplified via a SState power section"". [I call it the "ReAmp system" for short.]
I got the basic idea from the Guytron GT100 and thought it could work just as well with SState output.

As I had exhausted most of the other ways to attain good sound with all SState and this idea was modular and the Tube section is not expensive to make.
I would love to see/hear an all SState amp that does the tricks but until then my hybrid works fine.

But I,m always on the lookout for new ideas.
I did try the Valtronices gear but it was a sad excuse for guitar tone ,, [IMHO]
even some of my own SState Amp build attempts where better than those.

Anyway this is my first post so thankyou Teemu for the book, , a good read.

Cheers all, Phil Nambour Australia.
