Thanks. I have no place locally to audition either. The guys at Acoustic Sounds carry both and recommend the Chord. After reading the thread I tried to find the alternate power supplies that were referenced - no luck but might not have used the proper bait in Google. If you should know of the power supply upgrades and could provide a link would be wonderful. They mentioned iFi USB power (not sure how that would connect to the Chord), Squeezebuster and Mainscables.
