36v, 72v active filter on AudioQuest IC

In talking to an AQ rep once, I was told the maxium useful voltage is somewhere around 60v. Anything above 72v doesn't improve the sound.

The dbs packs do work to keep the IC run-in all the time so if you don't listen to you audio system often, the ICs are always ready and the dielectric doesn't have to re-form again. However if you listen to your system often, I'm not really sure if dbs makes a big difference or not. I used to own high end AQ but prefer the sound of unshield cables that reject RFI/EMI by there geometric design....at least in my system.

The 72v batteries are 12v each and there are 6 of them in each battery pack. They are not of the AA or AAA type of battery. They are about $4-$5 each but don't need replacing for quite a while since they don't carry a load.

Hope this helps.

As for the Sky, it is a great cable at a great (high) price. Niagara will save you 40% to 50% on the used market, and the sound quality is not much less. See this review:

Again, when dealing with the lower line AQ cables, put the money for the dbs upgrade toward the next higher AQ cable.

This is for Nick778 regarding his responds. When you said the person at AQ rep did not think the higher DBS than 72v will improve the overall sound, why is the new Signature WEL packed with 144DBS? and did he say it base on experiment? I have blown up every 24DBS and 36DBS that came with those cables, all my AQ now either have the 48DBS or 72DBS on them. That how I learned, you have to balance those DBS.

I agree completely with Nguyen357.
I did all the comparisons with Cheetah + Sky.
All run with 144V in my System. Huge increase of Soundstaging.

I have the Colorado interconnect, upgraded from 36 v. to 72 v. by upgrading the battery pack. How do you do the upgrade to 144v ?
