Richard, given the dedicated lines and your comments re a low noise floor and lack of grunge I'd suggest you buy more software, not hardware, and enjoy more music!
Power Conditioner Helpful?
I have dedicated lines with Cryo'ed Hubbel outlets and good power cords. My sonics, which mainly come from analog, do not sound at all grungy and the background seems pretty black. But I do live in an audio tunnel and have no chance to a/b or hear other systems so there is the chance that I don't know what "better" could be. Do you think I would benefit from a power conditioner? Cost/benefit is obviously important. My front end is Avid, Tri-Planar, Helikon with an Art Audio Vinyl One. Thanks.
