Rebbi,
I don't listen to large scale symphonic music very often, but when I do it's enjoyable and engaging in my system. I can relate to yours and Jet's comments. Before I got my SET amp one of the warnings was they can't unravel complex music. Implied is they're only good for low demanding simple music. That may be true for lesser SETs or if there's a poor speaker match.
The first time I played a classical orchestra CD(RCA Living Presence CSO late 1950s) I was nearly stunned by how good it was,layers od depth, fine separation,clarity. Nothing fell apart or collapsed. Now I wasn't listening at peaks of 110 db(I just don't listen at that loud level). The music was at a volume I found to be very satisfying and involving, that's good enough for me. I would likely require a more powerful amp if that type of listening was my primary fare(but it isn't). I truly enjoy all genres of music when the mood strikes. For the most part it's a large collection of jazz of various size groups. The point is you have an excellent amplifier that with appropriate speakers will allow you to enjoy whatever you like at a very high quality level of reproduction.
