Undertow, I noticed the same thing when I changed from the basic 18 gauge PC over to a Belden 14 gauge PC on my DAC. I also heard an improvement when I plugged the unit directly in the wall verses into a power conditioner.
I'm not a huge believer in the PC thing..but I did hear a difference for the better going with the 14 gauge Belden verses stock PC. A friend and I also tested the Belden against a TICE power cord which was something like 8 Gauge. Again the Belden was the better of the two PCs to our ears.
The key is a good PC..not necessarily an expensive one though.
