I have a question. The new Sherbourn 7/2100 seems like it will be a great amp. The 5/1500 has always received great reviews and seems very popular here. My question is: does the 7 toroidal transformers/7 mono blocks and heat sinks offer a distinct advantage over a similar 7 channel 200 watt amp with a different design. For example, I know most of the other multichannel amps (Anthem, B&K, Aragon, Outlaw, etc.) have only 1 or 2 toroidal transformers, and seem to get pretty good reviews as well. Any opinions?
