I am guessing you are using the P3? or the next one up, the P12? For two years I used the P3 and plugged my Preamp, Transport, Phono preamp, DAC, streamer and PS Audio M700s driving Magnepans into it. Never once had a problem. Upgraded to M1200s plugged into the P3 thinking I might need to upgrade the P3. Ran with the P3 for a year, no problems. I wanted more outlets on my powerplant so I upgraded to the P12 which has a wattage meter on the front. Running louder than I'd care to listen to for very long, it has never peaked above 500 watts usage. 95% of the time those amps are using very little power, even at 80 db and the Maggies are running full range. This has been my experience and not only does the P12 improve overall performance, the level of protection provided is very comforting.
