I thought I post this. I had an Audio guy wrote me to tell me to disconnect the DBS 74V from the power cords and see what I thought. Well, I tried it and wow the impact was huge, with more real presence, weight, detail, and more natural sounding. They sounded really good before but now like a new system. Still open but now with more body to the music, bass more solid, less light in the mid-bass. Anyone who owns the AQ cables with the DBS, give it a shot and unplugged the battery pack, and see what you think. I like it on the I.C. and speaker cables though and there I keep the DBS plugged in. But the power cords are a different story. take seconds to do and it is free and cheap, like your feedback on what you heard also. I was very, very surprised.
