Mono blocks are better or Stereo power amp?

I also prefer monoblocks for the same reasons as Aball. In addition, I prefer to place the amps on a floor stand near the speakers. The downside of monoblocks is they take more space. If you want to place your amp in a rack with the rest of your gear, the bulk may be problematic.

Monos are better.In addition to what's already been said, if you use monos you can use longer interconnects and shorter speaker cables.The end result is less degraded sound.

Vishalonly, stereo power amp can be very good and undistinguishable from mono's. Some people are buying monoamps because they are mono's, but for the same money they actually can have a better stereo amp. This is a bit similar situation as to biwire or not to biwire (but using a better single wire speaker cable).

I agree that all things being equal, with the bigger power supply afforded by the increased room, as well as less modulation between channels, monoblocks will sound better. However, I have some Essence Emerald III monoblocks and an Emerald II stereo amp. The monos have a bigger power supply but the stereo has a much higher bandwidth. In my system the stereo sounds better IMO. So in this case the circuit design trumps the larger power supply.
