I've had the Chord in my system for a 30-day demo from Acoustic Sounds. It is a keeper, delivering a nice full sound with great detail.
Of course, I too wonder what a more robust PSU would bring to this dac, if anything. I did just email Dusty Vawter at Channel Island Audio asking if they have a product that would work (his PSU for an older MSB dac worked very well for me). If, as Wtf quoted above from Chord -`it needs at least a 12V output to work properly' - I wonder if the 14V PSU that CIA lists might be acceptable (VAC1). Just don't know enough about this sort of thing to know what is possible.
