The primary argument for monoblocks other than shorter speaker cables (which by itself is a pretty important thing) is that there are no shared power supplies. An amplifier that has separate internal power supplies will be described as 'dual mono', but most stereo power amps do have shared supplies. In most stereo amplifiers, the incentive is price, as the chassis is often the most expensive part, followed by the power transformers.
Conversely, monoblocks are usually built to a higher standard as cost plays less of a role.
Overall these are generalizations, but good to keep in mind when looking at a specific product. They often are helpful in guiding one to an audition, but the audition is really the bottom line.
