Well, I am playing the Sunray right now with both amps, that is the Gakuon 211 amps on the borrom end and the Gakuoh 300b amps on the mids and highs. In my room the systems sounds very dynamic. I do not believe that I need more power, not even for the symphonies of Mahler, Bruckner, etc. However, I am sure that with big solid state the system would sound even more dynamic. But I prefer the subtlety and finesse of the Kondo amps to the big solid state guns. Some folks will probably argue that I prefer (Kondo) tube coloration, but that is allright with me. The Kondo in combination with the Marten Supremes and Tidal Sunrays create a very humane sound that I like and that resembles somewhat the feeling of live sound I experience regurlarly in some of the fine music halls.
