I have tried a lot of power cords and interconnects with the Cary 306/200 and find the FIM Gold AC power cord and Quattro Fil interconnects work best in my system (Cat Ultimate MKII preamp, Cary CAD 280 V-12 200w Monoblocks and Piega P-10 loudspeakers with a Rel Storm subwoofer. Not even an NBS Statement AC cord or the Nordost Valkjra interconnects did as well. The FIM Gold adds transient speed and heft while removing a touch of congestion and providing more soundstage depth and air and the Quattro Fil helps in some of these same regards, while not impeding others.
