I'm deeply suspicious of cables and yet I think they can sound different--not always better--just different. As standard, inexpensive cables, you'll do well with Signal Cable, Mogami, and Blue Jean. I tried stepping up to Audience 24e and just couldn't hear the difference so I sold them. Finally, I bought some Analysis Plus 9s for speaker cable and the Analysis Plus Crystal RCAs--they sounded better in my system. YMMV. By the way, Analysis products are unusually well made and fairly priced (relative to some). They're a great buy 2nd hand. My system is Luxman 505ux, Harbeth SHL5, Bryston BDP1 and Line Magnetic DAC.
