ALWAYS... ALWAYS... ALWAYS...
IF you can't hear the difference (s) DON'T pay the difference.
I think there's a decided difference between listening to short term A/B testing of cables, and long term testing/listening to cables, for one thing.
I feel the recent interconnect cable version that RS offers for $20 @ 6ft. are great. Not the last word in ICs for sure, but definite no brainers in the < $100 MSRP. Maybe it has something to do with the 'coaxial' build... I don't know.
They aren't as articulate as my Micro Pearls and are closer to the Audio Art cables in resolution, but a bit firmer overall.
They are definitely not close to the HT Magic II, nor SR Resolution Ref x2 active or any other upscale cabling I've encountered.
But for modest to mid level HT... a second or third system, or office rig, they are slam dunk wires. No kidding.
