Reprince , I don't like these 901's without the equalizer, the equalizer lets you hear the full potential of these 901's.. period ! It does NOT degrade the sound !
If you look down this page your see that Jeff did NOT use the equalizer with his reference gear and we all will find out about this in a few days when Jeff writes part three of this review...
http://www.stevehoffman.tv/forums/showthread.php?t=279685&page=9 He needs to hook up the bose equalizer with his reference interconnects and put it in his reference system and do this review the right way, he's being very unfair by not using the most important part of this 901 system !!
