FWIW -
I just replaced some comparably priced Furutech U-4.1T with the Bryston SC-4. The SC-4 produced noticable improvements, tighter and a little deeper base, smoother highs and a little more detail. I bought 20 feet of the SC-4 and given the results it was well worth the investment, especially at $9.00/ft. I couldn't be happier with the stuff.
