If you're going to spend $2K, get a Electra Glide FatBoy Silver 2000 for digital gear. It's the best "money no object" power cord for preamps and digital gear.
Why not PS Audio's Lab cables?
I have perused the "cable" forum, and I tried to do some research on PS Audio's power cables. I have never auditioned any power cables yet, but they seem to be great on paper, being they use higher gauge and more shielding than any of their competitors, and their price is much more modest. However, I don't see too many people in this forum using these cables. Why not?
