Thanks for your help Alexander. I'm a bit confused, though. The manual says to turn off the amplifier. OK, I guess there will be enough power going to the cans without the amp.
But then you said "hopefully your amps have volume controls, etc" ....
I don't think my amp (Adcom) has mute switch or standby switch, and I know it doesn't have volume control. Are you just saying this because it would be a little easier to NOT have to turn off the amp?
Thanks again!
