Mono block amps vs stereo amps? Well, this subject has been addressed before on this site and I have added my responses. However, here are some issues. Do mono block amp operate and ultimately sound better than stereo amps? Depends on the amps, period. It is always (electrically) better to have the amps situated such that the speaker cables are as short as possible. I x I x R (I sqared R, or power losses) in wires dictate that the longer the wires, the more power is lost due before the signal reaches the speakers. this is why power transmission lines are of significantly higher voltage than local distribution lines. Less power losses. Basically, the signal will degrade and have losses if the wires are long. It is better to have short speaker wires and longer interconnect wires. Also, if you are comparing mono vs. stereo. You have to compare apples to apples. You can't compare using a speaker that really is a difficult load and say go to amps that really can't drive the load. what mono amps do is to take the burden of driving both amps away and splits it within two separate amps. Most (not all) stereo amps use a single power power cable and power supply to drive both channels. Take away the fact that you eliminate crosstalk between channels, you also relieve the amp's power supply of the burden also. And, if you have separate power outlets that run back to your panels on opposite sides of the incoming power (different phase), then the power supply in the panel doesn't get overly burdened. Get matching specs amps, one is a stereo amp and two mono amps that have the same specs and the mono amps will definitely produce a better sound. but, use a massive stereo amp vs two very small mono amps that probably couldn't handle the speaker load by themselves anyway and the sound would suffer. This is not the haves vs the have nots at all. It is the same logic as why you use separates in the first place. Just step back and ask why you use separates and you answer your own questions.
