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.
