Hi kalali,
Like Erik was saying; you try a test on the inexpensive aspect; like Cullen Cable, Ice Age Cable and Signal Cable.
See if you can hear a definite improvement.
Personally, I use Cullen and Ice Age. Excellent quality, great prices and an unveiling of the overall sound. ( on my setup, of course), minus Martin Logans.
