Learning the hard way about AC power solutions


A number of years ago, so a different system back then, I heard subtle but definite improvements when I inserted my new PS Audio Power Plant Premier regenerator. So, tighter and punchier bass and greater pinpoint focus applied to images. I was convinced that my regenerator improved my sound and helped to protect my gear. Back then, I had Thiel CS3.6 speakers, a CJ power amp and a BAT line stage. Today, my system is quite different and much more revealing of what you connect to it.

As I upgraded my gear over these years, I left my regenerator connected, because I could still hear improvements when I upgraded my phono stage, my speakers, and finally my power amplifiers. One of my dealers told me one day that my regenerator hurts my sound, but I knew better, and he was selling high-end power conditioners that made me think that a sales pitch may be on the way. This was probably the first time, that I would not follow his advice, because I knew better. Hey, hearing is believing, right?

We bought a new home and now I have a completely different room, that includes a lack of full corners to support my speakers' reflected sound. I was missing body, so missing some fill-in, and a loss in bass energy. My Horning speakers are rear-ported, so are somewhat dependent on those corners. My dealer recommended adding quality subs or going with different speakers. Yikes! So, I'm talking to a manufacturer's rep of British subwoofers and I had sent him pictures of my system and my room. The first thing that he noticed, was my regenerator on my rack and he asked me if I ever unplugged my gear from that and went straight into the wall instead? He told me that he heard that the regenerator sounds worse, but over time, and because of this I might not notice those changes. I was still a believer of my regenerator, because I could keep hearing improvements.

Recently, I've been working on my AC power in the new home. I've been wanting to add a whole house surge protector, and did not want go straight into the wall without some kind of surge protection in place. From a buddy, I borrowed a Juice Box One, that provides some conditioning and costs around $800. I was in awe by what the Juice Box did for the sound, or by what my regenerator was hiding. Imagine, getting one of the biggest upgrades in sound quality by removing a fairly pricey product that was designed to improve your sound. This switch out, added layers of dimension to the soundstage, opened up the sound, filled in more body, and made the entire presentation much more musical and alive. A/B testing between the two, the regenerator now sounded sterile and almost dull in comparison.

The regenerator still had a feature that I could use, and that was to monitor the AC power coming into it, as it displays this info on its front display. In my old house, my AC input varied by about 5 or 6 volts during the course of the day. However, my new house only varies by one volt, so I asked myself, do I even need conditioning? I had already added two dedicated circuits for my gear with isolated grounds, so maybe I only need surge protection. Plus, I now needed to return the Juice Box One back to my buddy.

With 16 inches of snow on the ground and my AC panel outside, I procrastinated, and pushed back the whole house surge protector project. So, instead, I wound up getting a Brick Wall surge protector with eight outlets, and I read some good things and a couple of so-so-things about the product. I needed to try something without the regenerator, so this was my test. The Brick Wall is about one tenth the cost of my regenerator. So, a worst case scenario, I move the Brick Wall over to my TV if it fails the test.

I removed the regenerator and plugged everything into the Brick Wall. I experienced the same upgrade in sound quality with the Brick wall that I experienced with the Juice Box One. The other day, I decided to take the chance and unplug only my power amps from the Brick Wall and go straight into my dedicated outlet without surge protection. I got this from one of the so-so reviews about the Brick Wall regarding power amps. This kicked up the dimensionality and musicality of my system yet another notch! In my case, this was yet another lesson that less can be more. I am now done procrastinating about adding the whole house surge protector, so let it snow!

I have also gotten back from this experiment much of the missing fill-in, so more body, even with my existing corner situation. Yes, I still have less bass energy with my room setup, but the improvements have become so great, that I can easily live with this setup as is. Will this work for everybody? Does it only work with certain types of gear? Do you have decent AC power? I don't know, but I encourage those who are willing, to at least give it a try, but think about using some kind of surge protection for safety if you do.

Oh yeah, I already got the "I told you so" from my dealer.

TY- Kenny.


you bet location matter, especially, if you are on the grid of one of our major U.S. cities. Big city living is laden w/ black & brown outs that will

decompensate everyone's electricity.  Country living is where it is at!


Keep me posted & Happy Listening!

Exactly how many years ago would that have been ?

Electrolytic capacitors will degrade over time and are probably the source of most components SQ degradation.

I've heard that NAIM recommends you return your NAIM amp after 10-13 years to have it "re-capped"

Personally - I have re-capped the crossovers in my speakers and found a huge difference in performance - but then I upgraded to mundorf caps in the process.

So perhaps your regenerator is just feeling "a little tired" and needs some perking up.

Remember - the regenerator is working for the sum-total of ALL components plugged into it - so it's really overworked by comparison to the rest of them

BTW- there could be other components in their that also needs some "perking up" so I would recommend taking it to a qualified technician - not all of them will touch a power supply - let alone a regenerator.

Better still contact PS Audio and see what they have to say about it. At least ask them for the name of a reputable service centre.

When I lived in town, we had at least ten power outages a year. And, my house was at the end of the line. Now, I think I can trust my power enough to take a barebones approach.

williewonka - If it's the caps in my regenerator, I would be disappointed, because I purchased the PPP in 2009, so just before I started to upgrade my gear. I used to live in Boulder, and could bicycle over to PS Audio, so I have used them for service in the past. I did replace the caps in my Boulde L3AE line stage before I re-inserted it back into my system. I know that made a big difference.



I use isolation transformers from Plitron. Raw transformers are relatively inexpensive, but you need to have them installed correctly and inspected.  Plitron also sells complete boxes. They sell direct.

The electrical inspector said, "I used to work in a power station, but this is the cleanest power I've ever seen." I agreed. I could hear the difference. Exotic cables made a positive difference without Isolation, but not with isolation. An exotic power conditioner made a positive difference without isolation, but not with isolation. Isolation was better than either alternative alone.

The best part: it's physics, not subjective.

I tried different passive conditionners for many years. Now I ordered a big Torus  and hope it is end of the story
