Tons of great suggestions, thanks to all! Let me take this one step further. I have a DAC that has pre-amp capabilities. It's to my understanding that having a pre-amp (analogue) will sound better than the digital attenuation. If I'm just looking for a volume control, do I need such an elaborate pre-amp or should I even bother and just stick with the DAC?
Maybe I should start a new thread on this...
