Dave_b - I believe I understand your comment better now WRT what for you would be a realistic music level. And I agree, a Shostakovich symphony and comparable large scale classical and other works are better heard at higher SPLs generated by full-range systems. However, I still believe that low powered amps, when partnered with appropriate speakers, can do a superb job of rendering highly musical presentations of other musical genres, e.g., solo vocals, some solo instrumental works, and many small ensemble works. I guess this is one of the reasons I have chosen to have multiple systems. When I want to hear large scale music, I listen on a system that includes Verity Fidelio Encores, a REL B-2, and a 225 wpc SS amp. When I want to listen to solo instrumentals, solo vocals, and small ensemble works, I listen to my Solovoxes powered by Wavelength Cardinal X2 300B monoblocks. In each case, I find the music to be just the way you described.
Happy Listening!
