However I have never gotten a clear answer when using a newer iMac. I have heard the iTunes, and Mac volume controls introduce distortion but the problem has been dealt with and can be used without affecting sound quality and I have also heard to not use it. Same goes for Mac volume control.

But I really like the keyboard/remote based volume control in the Mac.

Anyone have some more input on which volume controls are best to use.

Thanks.
I guess the standard answer is to stick with the amp VC and leave the others at max if possible. But if you like the Mac VC, try it and see how it goes.
