I bought, back in the 90's, Audioquest solid core speaker wires for $110. I thought that was overpriced at that time and I really heard NO difference in sound from plain old speaker wire. I also paid for two pairs of their PBJ interconnects. I still use these cables to this day so I'm under $200.
Yes, I tried connecting other high end cables with NO audible improvement so I'm happy with what I have even though I paid too much.
Doesn't anyone believe in Science? The recent test by ASR of cables costing $7 vs. cables at $4000 were exactly the same!! This is not that hard to understand.
