I always wanted to be part of a group that compared speaker cable or power cords. I've never been able to do any real type of comparison on my system, as it's too hard to get the gear into and out of my rack. The best I've done is compared the A/D from my CDP with the A/D from my preamp. (Using different cables) And even this took going back and forth for the same part of the song, over and over again. I just bought some cheap cable that's been well reviewed and it'd be interesting to compare it with better, more expensive cable.
