I did not buy this cable from Amazon, but the manufacturer directly. The cable is very well made, and worth the money in any case. However, I have found that it enhances the low frequency range, and the middle or minor heights have losses. Previously I have used normal bulk cable, and given nothing to the discussion on the cable sounded. I'm surprised. My system is several decades old (amplifier Bj. 1979 LS Bj. 1982) and had it upgraded with these cables on. I recommend these cables remain fully.
