Anyone experienced a regenerator making their equipment sound worse?

Just had a rather curious experience. I recently moved my PS Audio M1200 amps/BHK preamp pairing from my main system and installed a Luxman M700u/C700u pair. Surprising to me, the Luxman pair is even more revealing than the PS Audio pair. When I tried using my PS Audio P3 regenerator with the Luxman c700u preamp and Luxman D-08u disc spinner so much leading edge detail was revealed that even slightly sub-par recordings were unlistenable to both my wife and I. (Speakers are 2nd generation Tidal Piano Ceras.) We just kept having our attention focused on slight distortions, too close miking of instruments and voices, etc. I’ve tried changing power cords and different vibration control feet on everything in the front end and nothing altered the impression of over wrought detail, just too much of a good thing. I pulled my PS Audio Dectet out of “retirement storage” and it sounds much better than the P3 regenerator in this particular context. Actually it sounds wonderful, everything is in perfect tonal balance now. The P3 is now doing power duties in system #2 with the rest of the PS Audio stack and sounds just as great as before. Anyone else experienced anything like this with their regenerator?

I have a P12 and M700’s. I have found that the 700’s sound much better plugged into the wall.
I tried every zone with amps and every setting but the amps sounded much more alive out of the wall.
The amps sound fine with the P12 but the life seems to be sucked out of the music. I know this should not be the case so I keep trying with the same results. My DMP and Gaincell sound much better plugged into the P12. What am I doing wrong?

From Luxman…your M700 U power amp requires 110 watts no signal so music will definitely
draw more wattage then in combinstion with your C700U requiring 28 watts then add your
sources…you may well be nearing the peak usa
ble P3’s power capacity…add your Tidal
Painos with a low of 3.2 ohms nominal 4…your Luxman M700 may well be choking by
the P3’s limited ability to supply power to your gear…so no wonder then that your Luxman
M700 U sounds so much more alive hooked straight to wall…

Just my own .0002…

I run a Parasound JC5 power amp from my P15 and it is wonderful. Plugging JC5 direct
to wall…not so good.

Perhaps time to upgrade to P12 or P15 when the fall sales come around.

Hey kline42

Not that you are doing anything wrong…but do try the following if you have not yet

Run your clean wave function for a full 60sec by pressing the clean wave function button

If you are using the multi wave function go to sine wave…music tends to be mpre open even
livelier ( for me anyway ) ymmv.

Another thing to try may be to shut everything down re boot your P12…that helps with a fresh
reloading of the os …helps my P15 from time to time as well…

Failing that shut down again and reverse the fuse orientation…even stock fuses respond
to this…

Hopefully this helps you some

Best wishes in your audio journey


I was just using the P3 for front end components, not the amp. Amp is direct into the wall.


I have a Furman reference series line stabilizer (not strictly a regenerator). I’m running both my power amplifier (I currently have my BHK 250 in the system) and line stage (Rogue RP-7 also currently in the system) straight from the wall. I’ve found my BHK Pre (currently taking a breather) is better overall run from my Furman. I dispensed a long time ago with the notion there is some canonical approach to power that benefits all systems and combinations of components. I believe it has a great deal to do with what the designer did in his/her component power supply topology and I leave it at that. Never succumb to dogma about what anyone says is a magic bullet. If it doesn’t work don’t use it. Relax and enjoy.


Oooops my bad Photon46…I misread thinking you were including your Luxman amp
in on the P3…Sorry my friend… My oh my
Best wishes

Some ideas:

  1. Is the power cord for the regenerator fully burned in (meaning at least 100 hours of use)?
  2. If it’s fully burned in, have you moved it? If so, I suggest 72 hours of constant power without moving the cable.
  3. If the above doesn’t help, try reversing the fuse, as David suggested. One direction is more detailed than the other, so you likely have it in the detailed direction.
  4. If none of the above works, you just might not like the sound of the regenerator in your system. I know a few people (not many) who feel this way.

Bottom line, all that matters is that you like the sound of your system.

Yeah, items one and two were in play and the fuse direction made little difference so #4 seems the answer. As you and Owlsalum say, all that matters is that one likes the way things sound. I was just rather surprised that the Luxman front end seemed so incompatible with the P3 as the PS Audio BHK sounds MUCH better when powered by the P3 as did my DeHavilland UltraVerve III. I’ve also found the Luxman gear to be less affected by Stillpoints, IsoAcoustics Oreas, Nasotec VEMs, and other footers than any other gear I’ve used. Thanks for all the responses.


I tried the M700’s plugged into a ‘Dectet’ as well as plugged straight into the wall. Had a similar experience.
Upgraded to a P15 a little while back (with some encouragement from the forum). M700’s are still plugged straight into the wall.

Obviously everyone’s power situation is different, but I found plugging my BHK300s into my Niagara 7000 had benefits, and in my other system I use an old Furman Ref15 which is also designed by Garth Powell, and provides extra energy storage for transients, and powers a Hegel H190.
