I suggest trying BPT's cables. (Balanced power Technologies)
The owner Chris is nice to deal with and his cables sound as good as ones that are about 3 times the cost and better.
We have tested BPT's speaker cables against a couple of good brands that costed over a couple of thousand and BPT's cables sounded just as good,if not better in overall performance. I have also owned the Signal cable, which includes Frank's Silver Series and to me they are very good for the money, but not as good as the BPT cables, but BPT's do cost more... Chris at BPT can also make interconnects of the same quality wire when asked.
