Having recently been called out over another thread on interconnects and their effect on sound, I shared the amount of experimenting I've been doing, it's to the point of tuning my gear with cables, I've found power to have a the least effect. One poster suggested purchasing high quality ends, have you thought of building your own? IMO with power, it seems more impact is with gauge rather than material - OFC/OCC/Silver. Home Depot carries 12GA 2 conductor w/ground for a reasonable price per foot and have found it to make wonderful power cables with the right ends installed. Although, the only instance where power made a huge sound dynamic change for me was pulling out a power conditioner I had - instantly it opened up my DAC and Pre to an entirely different level - all sorts of cable, receptacles, etc not so much - but it's a fun project; maybe a couple of PS Audio receptacles, copper rhodium plated ends and a run of the thickest gauge you can use. Post back what you end up doing.
