help with power cord


hello all, I have a system that consists of BAT Vk 3i, vk 200, meridian 508.20, aerius bi-wire, and transparent interconnects. i was wondering if I need to upgrade power cords. If so, which ones should i consider? My budget is around $50-100 for used pc. thanks.

I have tried the Harmonic Tech AC 11 and I thought my stock cord sounded better, so did my friend who I lent it to. Synergistic Master Coupler could be had for about 140.00 used, they are pretty good, I own one and felt that it marginally improved the sound. The high dollar stuff unfortunatly is where the big jumps in improvment occur. If you wanted to stretch you budget a bit the Powersnakes Sidewinder are said to be great, about 260.00 retail. I don't own any of these, but I do own Viper and King Cobras and they have made a world of diffrence in my system. They are quite a bit more expensive though.
Eljif, was your H. Tech. power cord properly broken in? It sometimes takes a good 100-200 hours before many H.Tech cables really strut their stuff. Granted, I would probably agree with your assessment if I was listening with you, but my H.T Pro-11 AC soundsexcellent for the money, and is a good choice for secondary pieces (subwoofer?) even in a high end system. I also have a Yamamura Quantum power cord ($1200) that provides a little bit of magic to my system, but my H.Tech PC holds its own in comparison. It was a signifcant improvement over my stock cord, and definitely worth the $160 price. ($125 at Audiogon)
I've been building the Belden 14 Gauge shielded cables for about $50.00 They use the Pass & Seymour plugs and Schurter IEC's. Solder all connections. Very happy with results.
In regard to the HT Pro 11 PC: I have used one on a CAL player and a Bel Canto DAC and it was a major improvement over each units stock cord. I am currently interested in auditioning the Mapleshade PC ($150.00) for the DAC out of curiosity as I really like the digital cable that I recently purchased from them. Other cords that I am considering in the under $200.00 price range (due to positive feedback) are the Silver Audio PC ($190.00) and the JPS Digital PC (used ones are just starting to drop in price). The Master Coupler mentioned above also seems to be very popular. As said before you may want to save up a little more before you buy and get something that will better compliment your gear. I am sure that some of the high ticket PC's are very nice but you can still see a major improvement as well (over the stock cords) in this price range.
