Mytek Dac going Ac to DC power.

Is a crimp on banana plug adequate for making a suitable cord, or is soldering necessary??

That Astron unit looked interesting, but I couldn't accommodate the size in my cabinet.
I ordered an sOTM sPS-500 power supply, when it arrives and I've broken it in, will report back.
I have the "original" Brooklyn DAC and when I'm streaming thru it for an hour or so it gets really hot.  I hope the PS improves the sound quality and reduces the heat.

agreed on all the comments regarding the Astron power supplies.  they are very good - replaced a Hynes unit in my system.

@erik_squires Not sure if you're aware of this, but the voltage can be adjusted on other Astron LPSU's rather easily...

Certainly not as convenient as rotating a knob on the face, but fairly straightforward if you've got a screwdriver and voltmeter.

pauken4 : Crimp on is fine.
