What are monoblock amps?

Monoblocks are two separate amplifiers, one for the left channel, and one for the right. Two monoblocks are needed for a stereo set, and home theater applications can use three or more. You definately get reduced crosstalk, because each channel uses its own separate power supply. You can also place your amps closer to your speakers, reducing the length of speaker cables needed. But you will probably need two sets of power cords(if you are into that thing), and perhaps longer interconnects, depending on where you locate your amps. If you do not know what monoblocks are, or are new to the hobby, perhaps a single stereo amp is best. But if you have the cash and room, or are into serious home theater, its an excellent way to go!

Instead of being stereo amps, a monoblock only amplifies one channel. That is, you need two of them in order to drive a stereo pair of speakers. While this may seem like taking the concept of separates to an absurd limit, there are benefits to be had in terms of stereo separation - hard for one channel to affect another when they are in different boxes. But the most significant benefit comes from being able to locate each amp close to the speaker it is driving. This means shorter speaker cables which is a very good thing. It does however mean another amp stand, another power cable, issues over lengths of interconnects required, wife acceptance factor etc. I also suspect there is an element of "cool" to it - the graduation to monoblocks signalling the entering of high-end arcana.
