I run both a stereo amp and mono blocks, not at the same time. The stereo amp is excellent and offers the following advantages...a single amp stand, a single power cord and the ability to hook up one subwoofer with no issues. It also takes up less space ( slightly). The mono blocks offer these advantages ( and they have mostly already been mentioned): better separation between instruments and slightly more depth, all of the attributes that Ralph pointed out above and greater flexibility of placement. For ultimate SQ--I think it is mono blocks, for less expense, it is the stereo amp.
Do Mono Block amps provide better sound ??
My question: do monoblock amps, that is, one amp per speaker, provide better sound than one box stereo amp?? I have read that a pair of mono amps provide the best stereo separation, imaging, soundstage depth.... Besides, taking up more floor space or rack space, and the necessity running a longer interconnect if each amp is behind the speaker, is it really worth it?? Thank you Jim
