I know my own reasoning for using my dac as a pre-amp as well, it's simply convenience for volume control with a remote and multiple inputs. But what are some of the other major benefits of having a pre-amp? And more so, why have an active pre-amp? Unless you are trying to alter the sound? Which I guess in some cases that's good because of speakers and room acoustics. I don't know, I think lately I have been getting too much into trying to build my system that I have gotten away from my own rule. KISS Keep It Stupid Simple. I remember one of my best sounding systems was ridiculously simple. Source-amp-speakers. It was a cd player,to a Decware SE84UFO to my Omega SUPER 3XRS's. Sound was sublime.
