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

for example the krell evo 302 has a 3000 VA transformer

The krell i have at the moment has 4000 VA per channel 8000 VA in total while its only 100 watts more , that was the main reason i bought it over a ML 436 which has much less .
Thats why krell monos are animals .
Oh and 1 thing i forgot a big powersupply has a lot to do with good basperformance ,another reason to go mono.
There is a clear cut difference as to why in theory dual monoblocks have an advantage unless of course the stereo amp is a dual monophonic design. Depending on the circuit design, stereo amps which use the same power supply for both channels is at a disadvantage. Power supplies can be taxed by the circuit it's feeding and this is multiplied by having it power a second channel. Usually, the sonic attributes of a using two monoblocks include a greater sense of depth, better inter-transient silence ( blackness around instruments in space), greater detail within that space, better sense of stage, and increased transient performance. In addition, an improvement might also be heard by powering each monoblock amp from a separate electrical circuit. This offers better isolation from channels
Thanks to all who have responded!!! I have been schooled in the pro and cons of monoblocks and single stereo amps. Cheers!!!!!!! Jim
I use to believe mono blocks always sounded better .... until I got a McCormack DNA-500.
