I am thinking about purchasing 3 aftermarket power chords. An internet site is offering 3 ft. 12 ga ptf shieldied wire with connectors that everyone seems to think are good. The price is around 100.00 each. Seems like a fair price for the products. I am not interested in replacement power cables from speaker cable companies at several hundred dollars each. Questions are: 1) Am I likely to detect any sonic upgrades from doing this and 2) 12 ga seems like an overkill in wire guage.
