Stellar P3 regenerator first impressions *UPDATED *

Thanks for posting this. It takes a lot for people to move out of their comfort zone and I am always impressed when they do. It’s not easy making big changes, but as as been said before, it’s good to step out on a limb because that’s where the fruit is.


I don’t know if there is a better indicator out there showing whether or not an upgrade was worth it. Thanks for the feedback Jerry!


I have a system similar to a couple of other posters (BHK pre,BHK 250 Amp,Directstream DAC & Memory player) And finally received the SP3 and got into the system the other nite (needed to build up a new power cable Supra LoRad 3x2.5 power cable) which has a 16 Amp current load rating.Listened several hours last nite intional sound was brittle and kind of hard but settled down a bit at the end of my listening session so the hope is it will only get better over time.

Yes, you can absolutely expect the sound to settle down a bit. I bet a decent amount of the brittle sound was powering everything down for a little, rearranging cables, and then warming everything back up. Along side of course a brand new piece of gear. Give it a few more days and everything will settle down well.

You’ve got a new piece of gear and a new power cord give it time.

It’s been a couple weeks since breaking in my new SP3. As I posted earlier this is replacing an AudioQuest Niagra 1200 that I really enjoyed. Some of the posters here were interested in the comparison between the AQ 1200 and SP3.

BLUF (bottom line up front): The SP3 is a keeper!

The brittle harshness of the highs and lazy bass have subsided after about 30 hours of play (2+ weeks being plugged in). Now, I am enjoying the hallucination of separation of instruments and non-fatiguing listening with treble, mids, and bass in great relation to each other.

Better than the AQ1200? At this point I’d say just as good at least. I expect SQ will improve with time.

I am very happy that I got in on the power the performers special, otherwise I think I’d have stuck with the AQ1200 - which wouldn’t have been a bad thing.

Great to hear and thanks for keeping us posted! Very glad the harshness settled down. That two week mark seems to be a good benchmark for folks.

Nice. Thanks for hanging in there with it. As you can see, it’s worth it. Thanks for the report.

This almost makes me regret the fact that our recent rapid power cycling didn’t damage my old P500. :wink:

I did some measurements on mine SPP3:
The loads were old classical lights bulbs => resistiv load.

  1. Load: 0W, Wall outlet: 232V, 0,29A, 10W, PF=14 (Power Factor), Surface temp: 29C, 84F
  2. Load: 75W, Wall outlet: 232V, 0,54A, 102W, PF=80 (Power Factor), Surface temp: 38C, 100F
  3. Load: 150W, Wall outlet: 232V, 0,90A, 194W, PF=91 (Power Factor), Surface temp: 47C, 117F
  4. Load: 190W, Wall outlet: 232V, 1,10A, 242W, PF=94 (Power Factor), Surface temp: 51C, 124F
  5. Load: 230W, Wall outlet: 232V, 1,31A, 294W, PF=97 (Power Factor), Surface temp: 53C, 127F

Efficiency: (Outlet-Load)/Outlet= X, (1-X)x100= E: (I hope I have done the calculations correct).

  1. 73,5%
  2. 77,3%
  3. 78,5%
  4. 78,2%

Voltage difference in 1-2h:
Wall outlet: 230,7-236,7=> ±3V
SPP3: 230,3-231,1=> ± 0,5V


Wow. Got mine installed on the upstairs system (not with its stellar brethren yet even) on a Peachtree (hey, it has a higher WAF, and is decent enough) where I am for now and wow. It’s never sounded better.

Thanks, PS Audio!
