Moved Audio Quest cable to my DAC. WOW


I just moved my Audio Quest power cable to my DAC and noticed a more realistic open and better detail. 

I have always been skeptical due to my electrical engineering bbackground.my wife also noticed a better sound. 

The cable never really made any difference on my JC5 amplifier but maybe as someone else pointed out,  power cords make a bigger difference on up front equipment with less sophisticated power supplies. 

Ordered a linear power supply conversion for my streamer.  Will see what that does.

I, too, had a similar experience with my Aries Cerat Helene DAC, but it was not the PC; it was the interconnect (Nordost Valhalla 2 XLR). I do, however, power the AC with an Audioquest Hurricane PC. The addition of the Valhalla 2s between my source and McIntosh C2700/MC611s was immediately apparent with the highs. McIntosh is known to be a little restricted on top, but no longer with the Valhallas. I was skeptical that the source cabling could profoundly affect the system. I always thought the preamp/amp connection would make the most difference. Boy, was I wrong!!

An excellent power conditioner with shielded power cables to all equipment are highly recommended. It's nothing to do with electrical engineering, but EMF contamination of the power cable between the conditioner and the equipment. Its probably only audiophiles who are aware of this phenomenon.

It’s a curse having an electrical engineering background. It holds you back from getting a great sounding system. You think too much about things, using that hard-learned logic to persuade yourself that things can’t possibly work. I was similarly afflicted, but have now learned to listen first, then having decided if the difference is there, and is tangible and worthwhile, then use that engineering background to work out what’s going on - how can that work? You have to think outside the box too.

I have a much better sounding system now, and better understanding of what matters.

Did you replug the cables BEFORE you moved them?

EVERYTHING EXACTLY as before? [i.e. different length that moved the power cables so one is not over the power transformer of another piece of equipment]

Line voltage checked?

Line noise checked?

Heavy load devices also operating? Hair dryer? Refrig? Heat Pump?

Engineers and physicist have beliefs just like everyone else. Selling stuff alters perspective.

Lack of rigor and confirmation bias accounts for most of what the untrained hear.
