DBS, the dielectric bias system really does make a difference. Once you break-in the dielectric, the DBS keeps them in that state even for protracted periods of time where no signal is run through them. What really opened up my ears to the concept was putting new alkaline batteries in my Colorado's and hearing the soundstage open up immediately. It was a stunner. Audioquest's designs have continued to evolve over the years...perfect surface conductors, teflon tube dielectric, spread spectrum conductors and now DBS. It makes me wonder what's next for them.
