Audioquest cables: replace the DBS Battery pack.

Bernhardknoop, your experience confirms what I understood should happen.
Elduende, I would guess that AQ has discovered that while 12v works, the higher voltages are even more successful in keeping the dialectric formed (not influenced by music signal levels or time). If you bought your DBS early on, your dealer might contact AQ and see if they will give you the additional battery pack as a courtesy, as they almost immediately began using them. If not, it seems like a reasonable thing to do, if not too expensive, especially if you like the cables.

You may want to have a look at Mike Mickelson's recent review of the Audioquest Sky on Soundstage. Mickelson seems to suggest that the static voltage bias induced by the batteries takes several days to establish after the battery is activated, and several days to drain if the battery is turned off. While Mickelson asserts he has tested the effectiveness of the battery pack by cycling the batteries on/off for several days per cycle, he should have sourced two identical sets of cables and interconnects: one set with batteries and one set without. This would have enabled him to make quick swaps for a more accurate/reliable audio comparison. Please see:

really good cables make a bid difference , it all depends on what you want to spend , AQ and MIT are the two companies that make the others lag in depth and clarity , any one with a really good system can hear it , don't think so , then take some regular rca's in to a really good audio store and have them change them out for you and you will hear it instantly

Wow, nine years til the last post. Anyway, I was a Synergistic Research nut (ICs and speaker), for a while. Then I auditioned some Audioquests and I sold off my SR stuff. The AQs were superior in practically every way. I'm lucky to have found them.
