I've enjoyed an MC452 for several years now and find that it pairs very well with my speakers. With a new home build, I had the electrician install a dedicated AC line and run CAT6 to my new listening room. Since all of my equipment is plugged in to a PS Audio P15 power regenerator, I'm not sure how much benefit the dedicated AC line provides, but since it was relatively easy with a new home build, I thought "why not", just in case it makes a difference.
