What are people’s thought on this as an “upgrade” to the QC’s included power supply?

Make sure the polarity is correct. QC is center-pin-negative. Many commercially available power supplies are center-pin-positive–I use one, and I have a polarity-reverse cable from Voodoo Lab to get center-pin-negative.

The other stats listed look fine.
