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.
