While I have no association with AQ, it seems many are misunderstanding what I believe they are claiming (whether true or not). The DBS is supposed to keep the cable dialectric "formed", that is, broken in. So comparing the cable with and without the battery connected should not actually make any difference. The better test would be to compare two of the same cables, after disconnecting the battery on one of them, after some period of time (perhaps days or weeks). If DBS works, the one without the battery connected would need some re-breakin time before it sounded the same as the one with DBS.
Has anyone tried this?
