Hi Flyfisher, At one point my complete system was Signal Cabled including power, speaker, Interconnects and digital cables. I have recently upgraded my interconnects, digital cable and one of the power cables and the difference IMO is equivalent to a component upgrade. I realize that Frank's cables are great bang for buck, having said that, I believe your components would benefit greatly by upgrading your cables. For what its worth, I recently purchased a pair if Z squared interconnects to replace the Ana 2's and I immediately noticed a tigher fuller bass, cleaner more extended high's, a blacker background, and more importantly there was no longer a dital glare(especially on women's voices)when the volumes was tuned up.
Anyway, best of luck on you upgrade path! you have a great looking system.
