Your dedicated lines may have helped. When I plugged M1200 directly into the wall, the dynamic increased a bit but so was the noise. The sound was not as smooth, and the treble sounded brighter. As a result, I could not listen for too long.
Even though my power line has never exceeded 2.2%, I still like it better with them plugged into P15. I may need to upgrade to a P20 to increase the dynamic (but not sure if it would make any difference).
Over the years Iâve had several Power Plants, starting with a P5. Theyâve always performed as advertised. And since I bought them for the sound quality and protection only, I keep my displays dimmedâunless the system sounds unusual.
I have always used 2 20-amp lines for the amps. One for Left and one for the right. When I added the two SurgeX SX-1120-RT over a year ago, it made the system less congested sounding without effecting the punch and dynamics. When I installed the P20 the dynamics and punch were gone and the whole system sounded very thin. Maybe two P20âs might have been better?
Indeed, thatâs always been my experience as well. Thanks for sharing.
After my M1200s were fully burned in I had the same experience. The M1200s sounded notably more fulsome and spatially expansive running through the Stellar P3. My DecWare Zen Torii also sounds better through the P3. My Luxman gear is the only exception, that set of components sounds better through my Shunyata MPC-12a.
Mine as well Paul from P5 to P12 to P15âŚ
Tried my JC5 straight to wall after having been accustomed to plugged into
P15âŚThat didnât last long âŚback to being plugged into P15âŚ
Great equipment power regenerators âŚcan only recommend!!!
Thanks paul

I must be an outlier. My Pass monoblocks sound preferable to be straight into their dedicated outlets.
I can gather from this info that every system is different and what works for some doesnât for others.
Iâm glad we have a choice.
You are plugging two M1200 amps into a P12?. I believe them amps are 1200w each. Can the P12 handle that much power?
There are quite a few variables involved! Iâve heard the same about Nagra HD amp.
It depends on the efficiency of your speakers, your room size, and the subsequent power demands required. If youâve got efficient speakers in a small or moderate sized room the M1200âs are loafing along with only brief intervals of higher power demands. I was beyond surprised the P3 sounds great powering my M1200s.
My speakers are 97db efficient and the M1200âs are efficient Class D, with 2 amps plus preamp plus music source into the P12, the system uses roughly 130 watts while listening to music. Plus 2 subwoofers with Class D amps.

Thanks, David. As we can see, not everyone finds the same thing in their systems. Itâs all about synergy.
And, in addition to synergy, preferences.
For example, some here prefer PCM; others, DSD. Both are correct.
A week of continuous power is 168 hours. You gave it less. The regenerator is at base an amplifier. What led you to expect full burn in in such a short time? Experience has repeatedly taught me to not take anything seriously until at least 250-275 hours, and itâs not uncommon for over 300 hours to be needed. Instant gratification and audiophilia donât mix well.
I didnât even have it for 4 days.
I suppose you think 300 hrs burn in would fix the issues I had with it?
It wouldnât fix the buzzing amp transformers, the 2vac from ground to neutral and the out of calibration distortion meter issues.
Besides the bad sound I was getting when powering my amps, these are the reasons I returned it.
The two SurgeX SX-1120-RT are doing a great job and my amps sound wonderful with them. They donât make my amps buzz ether.
Well that is a giant relief!!!
I can rest now!
Me Too. Also saved a ton of money.
Another concern is that the impedance of the SurgeX SX-1120-RT was more than half of what the P20 was and also cost a fraction of the P20.
Easy decision for me.
But now you canât do upgrades on the P20 and sell them here.
Poor Business Decision
I would pay good money for a mod that fixes the stock power outlets.
