I'll mention Audio art. I like Rob's hybrid III RCAs. I've used a pair of them with good success as main RCAs from proc to amp (s).
I also like the Cardas Neutral Refs, but they might tend to be pricey adding six or eight of them... even if bought preowned. They definitely are a clear cut "hear what ya got" with those wires... great mid range and top ends!
B4 I put much into ICs, I'd look into a pc for that player. My 980 responds very well to upscale power cords. I'd think the 83 does too.
