Sunnyjim,
I switched from Nordost 4-Flat bi-wires to Signal Cable Silver Res bi-wires. This was a HUGE upgrade for me. My system does not sound bring at all. I feel, in my system, the Silvers serve me pretty well. I do not have the urge to upgrade these. I did loan a 20 feet Ultra bi-wires from Frank about 6 months back and preferred the Silvers.
You can request Frank for loaners, compare the cables and decide which ones you like.
As Jeffb28451 mentioned above, these are great deals when it comes to audio cables.
