After 17 years as an audiophile, the key is honestly to try lots of different types of cable at different price points, because the results are so system dependent. In my pretty respectable system with a Levinson amp and preamp, Revel Studios, PS audio PWD, the best sounding interconnects and speaker cables came from Patrick Cullen at Cullen Cable, and thats after trying several $1k+ speaker cables and interconnects. In previous systems over the years, I compared boutique budget cables of those days to high end stuff and the high end stuff won, so you just have to be open minded and trust your ears.
