I can second the recommendation for Veritas Cables. I've tried so many brands over the years, many of which I loved. Some were very high end and costly, others not as much. But after all those brands I can't think of another which offered quite the same blend of value and performance that Veritas does. I've compared several different times with different categories (interconnects, USB, power) and although I can sometimes find another brand that gives similar levels of performance, it has always been a far more expensive cable.
At this point I've replaced pretty much everything but my speaker cables with Veritas products. Those will probably be next before the year is over.
