I have owned ARC amps, pre's, players and dacs, and have been loyal to the brand for near 30 years.
I have tried many cables, including ARC's orginals to the many types of Toshiba, Van den Hul, Cardas, Kimber,Nordost and have settled on JPS Aluminata for interconnects, JPS Aluminata for the amp & phono power cords and Nordost Brahma for pre, and c.d. power cords.
The cables which JPS produce seem to that special synergism with tubes amplification.
