I happen to like Reference Recordings to test equipment. In particular the Dukas Sorcerer's Apprentence. Most systems can't clearly seperate the Contra Bassoon and Bass Drum when they double each other solo. But for Classical CD's But Not RR:
Bartok Concerto for Orchestra -Solti, Chicago, Decca
Mahler Symphony #1 Levi, Atlanta, Telarc
Rimsky Korsakoff Sheherazade Conlon, Atlanta, Telarc
These three CD's played on absolutely the best DAC's will give most systems some problems played at full volume. I measured the Chicago Symphony at about 100 db AVERAGE SPL in the loud section of the of a live performance of the last movement of the Bartok.
