tube pre amp with tube / SS /hybrid power amp ?

You are pretty much describing Blue Circle gear. Most all the preamps are tube and most all of the amplifiers are hybrid.

It would help us 'Goners trying to advise you if we knew what speakers you were driving.

However, I too would recommend the Blue Circle gear, at least their power amps. I'm running a deHavilland Ultraverve 2 preamp with NOS tubes into a Blue Circle BC-28 tube/SS hybrid power amp. It is a low cost alternative to the all Atma-Sphere system I used to own. While not up to that standard, it does quite well without the heat generation and retubing costs. Very good tonality and clarity, overall a musical sound that can be listened to for extended periods of time without fatigue.

My father has on order a Aesthetix Atlas hybrid amp that we demoed with a Audio Research ref 3 (same pre as he owns) and the match is sonic heaven.atleast ith his Vandersteens.

If you get the chance, listen to the Sanders ESL amp driving the Vandies. It allowed the Vandies to breathe and a measure of expression which I had never heard before.

My favourite combination of tube/SS is the ModWright pre with the Sanders ESL amps. On the ModWright, change the 5687 tube for the Amperex 7119, then listen to music so sweet and natural, it suspends reality.
