Phil, I think that you have done very well to avoid higher priced cables and interconnects. Wait until you're well into 4 figures before you even think about it again. Spend on what makes the biggest difference, like better speakers and better amps.
Cables and interconnects offer the least bang for the buck, IMO. YMMV.
