Which is better, a mono block design with individual transformers or a single transformer design?
There are a lot of questions raised about using a mono-block amplifier design versus a single power supply. Using large mono-blocks in separate chassis using separate circuits are what the purists are talking about. By having a large power supply per channel with unlimited current being plugged into its own circuit is where some advantages exist. Krell, Levinson Pass Labs and others design mono-blocks to handle any speaker load with authority. Each channel of the amp are generally very large and heavy and are over engineered to handle anything that it asked of it. Once we talk about smaller amps using the same outlets, the advantage is exclusively down to crosstalk that is an over-rated specification to examine. In fact, some mono-blocks can be explained as a disadvantage in stereo listening as the small power supply per channel is sometimes too small for reference stereo listening and the amp can lack the ability to deliver lots of current in stereo listening. When you lack current, t
