I am guessing that 52V/6.5A power brick has got to be a switching power supply.Someone should do a DIY case for it!
I am going to sleep folks. No fighting while I am dreaming....
It would have been telling to have done a quick test to determine:
1. How much DC isolation (filtering) is provided by the PA7 design, and
2. How much audio-band noise is on the adapter's 52Vdc output.
A similarly spec'd power supply (~400W) may, probably, be sourced from aliexpress for reasonable pricing.
Why are there 3-pins to the "DC-IN" connector? Does the adapter provide 2 isolated DCs for L and R?
