PSaudio makes some nice stuff and they are easy to talk to-ask questions. I have had the Premier and traded up to the P10. The P10 works great, but i would not plug a medium size amp or large amp into it. I found they sound best direct to the wall. Sound stage suffered when amp was plugged into the P10, but still a very good unit. I now use High Fidelity MC 6 Hemisphere. Made a big difference in sound across the board better than the P10. The down size is you give up surge and spike protection. MC 6 Hemisphere is not for amps, front end gear only.
Good luck
