36v, 72v active filter on AudioQuest IC


Are they good and actually work, or this is a hype?
Want to hear from AQ's owners who have tried them with models without the battery.

Which model is their entry level with this "battery" application?

Did any1 upgrade from model with 36v to model that equip't 72v and hear imprvoment?

For some reasons, I see AQ is over rated. Fake ones (Hdmi from HongKong) are all over eBay....

I have 1.5M Niagara XLR analog interconnects with the 72v dbs power packs between my preamp and amp. They sound very good in my system - very close to the excellent Synergistic Research Tesla Accelerator ICs. The DBS system does make a slight improvement in air and soundstaging, but it is not as much impact as the active shielding technology of the Synergistic Research Tesla cables.

The entry AQ line with the DBS system is the Columbia. There is a big difference in sound quality between Columbia and Niagara. I do not think it would be worth the $$ to upgrade the Columbia from 36v to 72v dbs - put the money toward the Colorado series.
Thanks Dlcokrum, great infos.
Since Joelawn brought the "nasty shock" up. WOndering how can it get meassured up to 36v or 72v while the battery is only 1 (or 2)AA or AAA battery type?
Here is my experience with those DBS and AQ cables. To me, I liked the older versions, from Jaguar to Panther, Cheetah and then Sky. Sky to date, is still the reference cable from AQ until Signature WEL came out recently. If you fortunate enough to find the one was Made in USA, (I do not know exactly when AQ moved their productions to China), those are more refined than most. Those DBS really work wonders, smoother and more open sound. Take Cheetah for example, replace those 36DBS with 72DBS and you do not want to go back, believe me, I tried. Take Sky and double it up with 2 packs of 72DB, will take Sky up to the next level. Be warned, those upgrades must be equal voltage or the lesser ones WILL GET DESTROYED. Say 2 packs of 72DBS or 2 packs of 48DBS. You can not go 1 pack of 48DBS and one pack of 72DBS, got the idea? you can forget the idea of upgrade them to AA or AAA, those will harm your cable rather then help them. Look up AQ SKY reviews people seem to like them a lot. If you have money to play around with, then get Signature WEL with 144DBS, then it's the end of the conversation. I wonder why the new WEL came with 144DBS? any thoughts?
