+1 atmasphere. People usually listen to rock/pop at much louder volumes so a bright system becomes more obvious. Same system may "seem" to sound better with jazz at lower listening volumes but that's just a misconception and becomes clear as soon as you hear both genres on a tonally balanced system.
which is a better match for best results
Hi ,I have a Krell Evo 402e, which is the best suited pre amp for rock and jazz , I can get a Audio Research 5 SE or a Krell Evo 202 for the same price, anyone with experience on both? thanks for your help
