some questions for P3

I am using P3 to power my naim system with CDS3,202 preamp and 200 amplifier. Some questions:

  1. now i use zone A and B to power CD player and preamp. Should i must use the socket of zone D for 200 amplifier? I don’t think it is must, because i found the power consumption is ony 50~75w as the display indicates when i try to use the zone C socket for amolifier (but not sure if there is any dynamic lose).

  2. There are different logo marked on the sockets, some are marked with TR and printed PS audio logo, the others printed wth AV grade. What is the difference on performence?

Nothing. There is no difference on those plugs. The markings are there for the plug manufacturer and nothing else.
