daveneumann,
Thanks for this additional information. While I know it's only an opinion this is very good to know.
I was talking to a friend that owns Pass as well. He stated that Pass do get hotter than many other amps (such as his previous Mc), but it shouldn't be a game changer for anyone who likes audio. He as you said more than likely I won't even notice it. He also stated that his electric bill only went up app. $10 per month after purchasing his Pass system - which alleivates one of my wife's budget questions...
Thanks again.
