Review of the new Synergistic PowerCell 10 and SE

I was very much interested in the Synergistic PowerCell after enjoying much success with the Tesla Cables. For many months I have waited to demo one of these babies.

My concern was this.

I have 3 dedicated circuits.
*One circuit for all my Video and is plugged into a Hydra 8.
*One circuit for my CD player and Preamp.
*One Circuit for my Amplifier.

How can using just one wall outlet plugged into the SR PowerCell be better than using the present 3 dedicated circuits?

My past experience with any conditioner says it can’t!
My new dealer however, said it will outperform the dedicated circuits. He then asked if I would like to demo a unit.
I replied, well, yes sir I have been trying to demo one of these for months!

A couple of days later I received the Demo PowerCell standard 10 with a T3 UHC power cable.
I’ve got to say, I had some pretty big expectations for this Conditioner based on the Dealer statements and the performance of the Synergistic cables.

But when I turned everything on for the first time I was really disappointed. Best I can describe it was, the sound was very closed in, with a totally flat soundstage.

I thought, Wow, after saving up so much money to buy one of these and now I was convinced that this unit was not an improvement over my 3 dedicated circuits.

I know new things need time to break in, but this one was a demo! It should have sounded at full potential right away.
My dealer also confirmed that it had many hours on it. He agreed that it should have sounded very good right out of the box.
I thought, well, whoopee! I can save my money; this just is not very good.

The next day I did not even play my system. The following day, however, when I did turn it on, my system sounded entirely different.
The soundstage widened and deepened and it was now much more musical.
I think, even though it was used demo unit, it traveled across county to get to me and was very cold when I got it. It seems these units need some settlin’ time.
Perhaps it only would have taken 24 hours to resettle but like I stated, I didn’t try it the next day.
By the way, later on when I also tried the Power Outlet Teslaplex it also took a day to sound good.

At this point, the PowerCell 10 was making some pretty good tunes, so I went ahead and ordered a PowerCell 10 SE. Note: I also sold the Hydra 8.

The new unit arrives.

Well I received my PowerCell 10 SE and a new duplex Teslaplex outlet.
The new PowerCell straight out of the box did not have the extreme closed in flatness that the demo had.
Perhaps the difference can be attributed to the different power cords. The SE comes with a Precision Reference power cord, while the Standard comes with a UHC T3. I have read elsewhere that the UHC T3 cords take a very long time to break in.

I plugged everything I had into it and left it on for a couple of days. I think the best way to break it in is to put a heavy load on it.

Well, now how did it sound?

Well the sound quality is now the best I have ever heard. Bass quality is deep and defined, treble sparkles and the soundstage is all through the room.
The dynamics are now such that the music jumps at you.
When I play Rock music such as the new AC/DC CD some of the tracks start with guitar just in left channel or just in the right. With this new PowerCell there is nothing coming out of the other side, I mean nothing, until it is supposed to. Quiet as quiet can be.
Then when the song gets going, the music explodes out of the speakers. It sounds really quite impressive!
I have noticed that I am getting more relative volume than I did. I have had to turn down the volume control from where my Preamp normally was set.

Watching Video through my Sony 60” now has deeper colors and better contrast. The picture just looks more involving. I was not expecting this much improvement with the Video.

I plugged my whole system into this PowerCell. Everything that used to be plugged into 3 dedicated outlets was now all plugged into the PowerCell using only one of the dedicated outlets.
Amazing, I would have never believed it. No choked sound, no loss of dynamics. To the contrary, as I stated above the dynamics were even better!

Comparisons of the two units.

The SE with the Precision Reference power cord compared to the PowerCell 10 Standard with the T3 UHC cord?

The Standard unit had a warmer sound; the SE version had more presence and the center image was very well defined.
With my equipment, I definitely preferred the SE.

Any Negatives? A couple… minor

First, I must say the feet on the bottom of the Powercell should be taller so that any Mini coupler plugged in the unit clears the bottom. Otherwise, you have to waste half of an outlet to plug a mini coupler into the top half of the outlet and it will overlap and cover the lower outlet. I ended up putting Myrtle blocks under the feet to raise the PowerCell up. Then, I was able to place a mini coupler in the bottom of an outlet and still use the top half.
Later on, I replaced the blocks with sharp cone feet. Highly recommended.

Second, the outlets take quite a push to plug the plugs in. This is a good thing perhaps for a tight grip, but plugging the plugs into the back of the unit had the unit moving around on the stand like crazy. So, maybe have another person (with the white gloves on) in the front holding the PowerCell while you plug your stuff in the back.

Third, I made a mistake and placed the 32 Amp power cord connector plug in last. This made it impossible to see properly to connect it. I think I got it connected; I pushed it in, but not sure if it locked. Should I hear a click like a XLR does?

Conclusion

Well, I highly recommend the Powercell 10 SE, it will make all your hard earned prized equipment perform to its best, you will be impressed!
The price is steep, but nothing should wear out and it can handle everything I plugged into it. Including with my Audio system, my entire home theater system.

Now, what to do with those extra dedicated circuits?

I had the Powercell 10 SE for one week now and here are my initial observations.
The first 3 days were dark and repressed sounding, which was expected from what I heard from others. I went away for the weekend and about a week later, I happen to go home for lunch. I also have been burning in the Powercell 10 SE since I installed it. I put in a very familiar and well recorded CD and pressed play and went for lunch in the kitchen. After the first song, I was drawn back to the room to sit and listen. The Powercell finally opened up... improvements noted so far... the soundstage got bigger and seems to have no limit, instruments are bursting from their exact locations in ultra clear clarity with lots of texture and definition, my midrange presence has improved. The music sounded more involving, more alive. The notes seem to start and stop quicker and become razor sharp. The black background level and separation of left to right is very noticeable and enhance the soundstage.

I assume some more improvements are to come over the next week. I was told I was just about there. Overall, I’m very satisfied and pleased with this power conditioner. The improvements over the PS Audio are just what I was hoping to hear in my system. The reason why I used PS Audio power plant premier was because I didn’t have dedicated lines. PS Audio unit adjusts to a perfect 120 volts and also reduces THD to a very minimum. I was happy to hear when Ted mentioned that he developed and voiced the Powercell not using a dedicated line. Anyway, the Powercell works leaps better than the PS Audio unit. I now understand the concept of not having any transformers or chokes for filtering in the power supply. Instead the Powercell uses an electromagnetic cell. To me, this unit is like using a direct connection to the wall. To my surprise, plugging my integrated amp into the Powercell sounds much better than plugging it directly into the wall. It seems purity has been missing from my system since adding the PPP and I did not realize this until now. If you can afford it and want a pure system that is very alive, give this unit a try. Dedicated lines are not needed for this unit to sound its best.
Hi Drubin,

All the observations in my review was comparing my entire system plugged into a PPP for over a year and changing to a Powercell 10 SE last week. I was amazed at how much more pure my system sounds now. I never thought the PPP was restricting anything until now. All instruments are noticed in a recording. Nothing disappears to the background and is missed. The loudness levels are turned up in a very good way on all sounds. Everything is illuminated and music is very involving and emotional. Also, with the Powercell 10 SE in my system, the bass is louder. I had to re-adjust my subwoofer. The bass on the 1027 BE’s is smoother and transitions much better to the sub. The sub disappears so much as if I hid it and you did not I have one. Drums sound so real. I think this is a hard trick to pull off for any system. The only place I ever heard bass sound so real was at a live event. Go figure. I'm just amazed by this power conditioner. The level of enjoyment I get from my system has increased immensely.
RETAIL PRICES:
Powercell 6 = $3000
Powercell 10 = $4000
Powercell 10 SE = $5000 but comes standard with a Precision AC power cord with 32-amp locking connector) A separate Precision AC retails for $1800.

The others you will need to buy either a T3 UHO or Precision AC power cord with a 20 amp connector but I think Synergistic offers packaged deals. Not sure of the prices of those.
Hi Laza,
If you upgrade to a Powercell 10 SE it comes with a Precision AC power cord with a 32-amp connection. To my knowledge Synergistic does not offer a T3 UHO with a 32-amp connector. I guess you can special order one but I dont see why since the Powercell 10 was voiced with the Precision AC. The Precision AC in my system out performed the T3 UHO with frequency extension and its ultra clear and neutral presentation. I suggest putting a Hologram A on your amp, get a T3 for your preamp since you did not like the Hologram A here. This will add back the warmth. What do you have on your source? If you have a CDP, get a Hologram D.

I think you should try this:
Powercell 10 SE - Precision AC
Source - Hologram D (If its a CDP)
Preamp - T3 or Hologram A (Pick the one you prefer)
Amp - Hologram A

Let us know.... Thanks! Joe
