[quote=mdrew}...I see pictures showing a receiver with mulitple amplifiers. Plus, John reads way too many tech manuals to be this wrong... [/quote]

Mike,

Receivers may not have physically separate amplifiers in the form of their own separate boards. But each channel must have its own amplifier even if all of these amplifiers are concentrated on one board. All of these amplifiers in an integrated receiver do share one power supply however as they do on a power amplifier.

Note that the A1400 has 4 boards...for 8 channels. Each board has two channels on it. Provided that each channel has "enough" physical and electrical isolation, each channel will not be affected by the operation of the other.

I am sure that John did not mean that a receiver has a single amplifier. He was trying to simplify the complexity of the point he was trying to make.
