Mytek Dac going Ac to DC power.

The Astron RS12A puts out 10 amps. The Mytek draws a constant 1.5 amps. I never saw it peak out any higher than that when in use. It does not create any problems using 22 ga. wire, unless you are using a long run, which is not suggested. My wire is less than 2 feet. The DC wire is certainly a "tuning point" for me, and different types/gauges certainly change the tone. I urge you to experiment until you find one that gives you the best synergy in your system. 

Some of the audiophile power supplies I had tried were the HD Plex 100, the Keces, the Vinnie Rossi Mini Pure DC-4EVR (ultracapacitor powered), and a Teradak power supply. Some of them may look nicer and have better specs. than the Astron, but my ears tell me which sound better, and that is all I care about. The low price is a bonus too.

@bigshutterbug Agree about ’tuning’ via wire @12vdc. I also tried many different types of wire between the Astron LPS and the digital component. The change in sound was very easy to hear. I ended up with 20awg OCC pure solid copper magnet wire.

To combat digital backwash, I added this ICT PCM 12ADL in-line between the Astron and the digital component. It cleaned up the signal even more. Three of these are in my system - between 3 Astrons and the modem/router, the dac and the dedicated laptop for streaming. These are in addition to the 120vac power conditioners that the Astron power cords are plugged into. Over the years, I’ve discovered that the digital components add a lot more digititus than one might realize.

Thanks for the tip on the ICT steakster, I'll look into that as well.
