Hi, Slawney. I'll try to answer all of your questions, but must start with one of my own. What does the abbreviation "PC" stand for? Phone cartridge or power cable? I'm going to assume that you did not "personal computer" .
Now to your questions:
1. Yes, I missed a small amount of inner detail, but that maybe have been because the PWX seems quieter than the stock power supply. I want to be clear, however, that the difference was not great.
2. I used two different cartridges in my testing: a Grado Sonato, and a Shure V15VxMR. Both were mounted in a Rega RB900 arm, which is mounted on a VPI HW-19 Mark 4 turntable.
3. I allowed the PWX power unit to warm up about 6 hours. The Black Cube is the one I've been using for about 18 months.
4. The power cable I used with the PWX power supply is the same cable that came with the original Black Cube power supply. At some point I may upgrade the power cable, but I'm skeptical that it will add anything to this unit because it pulls so little current.
5. My system includes a Bryston SP-1 pre/pro, Bryston 4B-ST and 5B-ST amps, Vandersteen 3A Signature main speakers, Silver Lace and Super Silver interconnects from HomeGrownAudio, power cords from AudioQuest, Kimber 8TC speaker cable, and Monster Power HTS2000 power conditioners.
