Hi Claude, the JRDG 312 is an amazing amp. . . I have not compared it side by side with 501 monos with PC-1s, so I can't really comment on differences.
I am no longer using Cardas Golden Ref speaker wires and power cords. I am now using Furutech Evolution II wires throughout the system. . . Extremely linear, quite extended, and no emphasis or trofs that I can tell. . . and very graceful treble.
