Do Mono Block amps provide better sound ??

Let's not forget John Curl.

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
