VW is spot on the money. Shielded power chords are very important to getting better sound from the 9 SE's. I have used Blue Circle BC-62, VH Audio Flavor 4 w/ Furutech FI-25 connectors, VHAudio Flavor 1 with Oyaide PC-079 connectors, Element Cables Standard and Red Storm cables, and Ear to Ear Black and Red chords with standard Marinco hospital grade connectors. The Ear to Ear cables were clearly the best, most likely due to the elaborate shielding and heavy guage silver coated copper wire. I use ETE power chords throughout my system now.
