I see - thanks for clarifying that I'll be running through two attenuators as well as 2 pre circuits.
I'm doing this because quite simply, I'm playing around. My main integrated has everything under the sun (dacs, mm, mc, rca, xlr, am/fm/hd) and I love using it for it's simplicity. However, some of my speakers sound better on other integrateds that I have previously paired them with. So, to keep my system simple (simple to me) I run 2 integrateds in the path. I know it's not ideal.
However, my question is, will running the second integrated wide open (attenuating it as little as possible) be harmful in any way? Does having an amp on max volume stress it in any way or is this just like a normal power amp (minus the eq/degredation of having the volume potentiometer) in the path?
