Hello everyone.

On my current computer based music system I have a total of 4 volume controls.(iTunes,Mac,uDac2,amp) Everything is maxed except the amp. From my understanding this is needed to maintain bit perfect output via digital/usb.

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.
