As Estmad stated the results may be different depending on the actual combination of equipment used.
In my case I run aftermarket power cords from my HTS 2000 to everything (also changed the stock PC on the HTS + hospital grade Hubbel plug) except amplifier that is fed directly from wall through Camelot Sir Bors power cord. Estmad the P 300 is in my wish list.......
I tried wall direct and through the HTS and with it I got the best results with my preamp.
Do some testing and make your decision
