Cables for Conrad Johnson and Proac D25 system

Beerdraft,
No, I haven't upgraded those, but probably should look into it. Budget for biwire speaker cables is up to $1K used.

Alextychkin, Unless your speakers have to be bi-wire my experience is you don't really gain a lot there from just a good speaker cable. That being said, I highly reccomend you get power cords first accross the board. You really need to audition them to make sure you like it. I auditioned several and found some to be nice and warm when plugged into certain components and found them fine in another. I found one line which was good all around though expensive I'm buying all shunyata. It is very warm and natrural and really seems to bring out the best in the cj gear I have. I found several other power cords not much less in price to be to dynamic quick and in my face which just made me want to turn the volume down. So depending on your taste you will do much more improvement on cords first then interconnects and speaker cable. I've actually auditioned all in the past week and its been fun becoming a believer in cords, never thought of it before I got this same advice recently. Trust me you haven't heard the cj or musical fidelity until you match them with a better power cord. Hope you have a dealer who will give you some stuff to try. let me know.
good luck

As long as Beerdraft brought it up you may want to audition some PC's first. I just upgraded mine (for a 3rd time) on my CJ preamp and Audio Aero CDP. I'll leave the superlatives to someone else but suffice it to say that it made a SIGNIFICANT improvement, more so than I've experienced with either speaker cables or IC upgrades.

Thanks all. The PC upgrade seems to be the thing to do. I've been very skeptical up until now about PC swapping in general. But the more I hear about the changes those cords make, the more I feel like focusing on that area first.

Alextychkin,
I have had great success with Kimber KS-1030 interconnects and Kimber Bifocal speaker wire between a PS Audio Digital Link III, Conrad Johnson preamp, McCormack DNA-1 and Proac Response 2.5's. I certainly agree with Beerdrafts and Jaffeassc's ideas on power cables; their impact in your system should be very large. Wishing you good luck!!
