Why monoblocks?


Why run monoblocks? Most amps can handle most speakers, especially those that are 88DB and above in sensitivity. I see pictures of all these speakers being driven in monblock configuration. If the stereo amp can do the job, why spend money on two amps? I mean, what are the benefits?

My belief is that well designed stereo amps will sound every bit as good as monoblocks, but short ICs is a real benefit, but low capacitance cables will amount to much the same benefit even if a bit longer. I simply would not buy an amp on the basis of whether or not it is monoblock or not, there are far more important aspects to the quality of amps then the issue of mono or stereo configuration, undoubtedly, some of the finest amps ever made are not monoblocks.

You guys hurt my feelings. I'm selling my monoblocs and getting a stereo amp so that I can fit in with everyone else.

First of all you get more power supply with mono amplifiers and there is a huge advantage to the left and right channels having separate power supplies.

Sonically there is a noticable improvement in separation and the soundstage is much larger with mono amplifiers. The same is true with mono or dual mono preamps.

I have achieved some of my best sounds with mono amplifiers with long interconnects and short speaker cables.

I really don't care how it looks.
There are valid engineering reasons for designing monobloc amps and I imagine that sonic benefits thereby flow. But if mono designs are really that much better then why aren't all ultra high end electronics monobloc designs? Where are the monobloc phono preamps, D/A converters or preamps?

For all those people using long interconnects/short cables, how do you deal with placing delicate, vibration sensitive electronics so close to your full range vibration creating speakers? There's also the issue of power amp transformers and woofer magnets/crossover components interacting due to their close proximity. I don't know this for a fact, but maybe long interconnects/long cables is really the way to go? Just something to think about.
