Mono Vs Dual Mono Amplifier

What the difference bewteen a monophonic amplifier and a dual mono one?

To improve audio quality, a Brand can choose to make an amplifier with a mono or dual mono design. The same is true for the players, preamplifiers, power amplifiers etc...

The better is the channel separation, the better will be the soundstage. So a mono amplifier will be better than a dual mono, and much more than the simpler designs.
