I have used the JPS stuff with my Rega Planet 2000 and Bryston 4BST with very satisfying results. I also liked the sound with the Jupiter 2000 and now my Bryston BCD1. Still use the Bryston to power the bass on my VSA VR4JRs via JPS FXs from my McIntosh C2220 preamp. I use JPS Superconductor 2s between the C2200 and my MC275 tube amp. Really, REALLY open, dynamic clear-sounding rig. After trying Many of the big name cables my first impression after installing the JPS cables was of a clear, open channel between my soource and my ears. The music just seemed to flow effortlessly. I'm also using JPS AC cords.
As I've upgraded components the cables have stayed and I've not been disappointed in the least.
