There are so many good cables that work with the Decware amps! Looking at my "extras" drawer I see Tara Lab RSC Reference, cyroset.com Version 2, PS Audio Lab xStream Reference silver, My Audio Cable (MAC) Silver, and Synergistic Research Alpha Sterling RCAs and WireWorld and Dyson Audio XLR, all of which I have used in the past and don't have a place for at the moment. (Probably should put some up for sale).
I'm using VooDoo Cable interconnects now and LOVE them but they are very expensive new and even used they take some courage to push the button on and order. Excellent cables though.
I've used Decware Silver Reference in the past as well. Good cables. . . I have just preferred others. At a certain point system synergy and personal taste both become deciding factors in cable choice.
If you can find a pair used a no-brainer choice is Granite Audio silver interconnects--these are phenomenal. Worth the price new, and rarely seen used.
The biggest surprise I have found in cable choice this past year is using AudioQuest coaxial component cables as interconnects, YIQ-5. Of course they are no longer made, but I found two sets used each for less than 100 dollars, about a quarter the original price. They are smooth and articulate and full-bodied; I use them in my audio-visual system in between ZROCK2 and CSP2+ and between CSP2+ and Taboo Mk IV (all three Decware components have the Mods.) Could not be happier with the sound. I just don't use the 3rd cable. Recommend trying these if you run across them.
