Most integrated amps have the preamp section connected to the amp section with a set of clamps (not sure of correct wording) If you remove the clamp you separate the preamp and amp sections thus allowing you to feed another preamp or a different set of amps.

Most modern AV receivers have 7.1 outputs that can feed another preamp or amp thus not using the ones in the receiver.
Kal & Edward..... Okay, so no reason to think that one preamp section can't be a [direct] source for another preamp...but I'm assuming that the unit being used as the primary preamplifier -- be it an AV pre/pro or an AV receiver -- would have to be manufactured with preamp outputs, correct?

Edward..... If the newer AV receivers you're referring to are designed with "7.1 outputs" that can be routed to a separate preamp or a separate power amp, what's the purpose of removing the "clamp" (or whatever it's called)?

No doubt, I can understand why isolating a preamp stage from its power amp stage, in an integrated amplifier design, would be ideal...but, after reading the first paragraph of your last post (above), I was thinking that the "isolation" was already taken care of via the preamplifier outputs you mentioned?
