I quite like the Audioquest Evergreen. Quality built and not too expensive at $35. Works great going from my 3.5mm connection on my DAC to the stereo RCA on my amp. Some people swear by cheapy cables, some swear by even higher end stuff. I think this is a great cable personally and would buy another in a heartbeat if needed.
Edit: Check Audioquest's website and make sure you're buying from an authorized vendor. There are several available on Amazon, but not all are legit.
