For a period of a couple years I went through high priced Tara labs, MIT, Kimber, Cardas and finally top of the line Marigo, also use for interconnects. I also played around with cheap cable just to see if I could here a difference and although I believe you can probably find a cheap cable that sounds awesome but I gave up after a couple cheap cable attempts.
The Marigo warmed up the sound better than any other cable with my system. Kimber were too tinny and MIT too flat.
I don't think many people know about Marigo but for my system the best, I believe the components play a large part in how a cable will sound and my NHT 3.3s a little bright on the high end may be the reason Marigo work best for me. Also was using a Plinius SA-250 and Sonic Frontiers pre-amp when i settled on Marigo
