ADD-Powr Sorcer x4

Field Based Power Conditioning

Pro Tweek: 

Replacing the stock fuse on the Sorcer with a QSA 5x20mm slow blow 500 milliAmp fuse takes the performance of the Sorcer to stratospheric levels. You have not heard your Sorcer like this. We guarantee it! Read more about this on our blog.

Adding a QSA fuse to your Sorcer ups the performance exponentially.

Sound and Video Like You've Never Heard or Seen Before. ADD-Powr technology is Algorithm Digital Defined electrical energy and power. 

ADD Powr's Sorcer x4 emits an algorithmically generated field to obliterate noise riding on AC lines. Your components do not need to be plugged in to it to get the benefits of this noise reducing technology. In fact, you couldn't plug a component into the Sourcer x4 if you wanted to, there are no AC receptacles!


The Sorcer x4 changes the quality of the AC line, using the emitted field to re-reference or bias the AC. There are no filters, isolation transformers, AC line regeneration, nor balanced power techniques. The Sorcer x4's unconventional approach to power conditioning leaves AC impedance and current capability untouched. That bear's repeating...

The Sorcer x4's unconventional approach to power conditioning leaves AC impedance and current capability untouched. 

  1. The Sorcer generates low frequency electromagnetic fields to affect harmonic energy change to audio signals and systems.
  2. The products condition AC line voltage through a low frequency pulsing action to effect an increase of the energy delivered to the power supplies of system components by .8 - 2.5 dB or more. This corresponds to a 10 - 25% increase of voltage peaks!

Instead of inserting a potentially current limiting component between the incoming AC and your components, a pulsed field now re-references, or biases, the AC signal.

Whether analog or digital signals, audio or video systems, consumer or professional, a new level of benefit is revealed with the ADD-Powr reference.

What you can expect

We said it best in our Tweek Geek Speek review of the Sorcer:

"Clarity, macro and microdynamics are, well, more dynamic. Imaging is precise, soundstaging is larger, and leading edge transients are sharper. All of the musical frequencies become cleaner, clearer AND more musical. There seem to be no tradeoffs with the Sorcer."


  • Dimensions: 17.75" x 12.5" x 6
  • Weight: 30 lbs
  • Voltage: 120 or 220


Q: My country runs 220 volts standard. Can I use an ADD-Powr Sorcer X4 here?

A: Yes, the Sorcer X4 can be ordered in a 220V version


Q: Do power cords influence the Sorcer X4?

A: Yes they seem to. Whatever filtering or tonal characteristics the power cord powering the X4 has, they seem to pass through to the effect the X4 has on the overall sonic presentation of your system.


Q: What if I plug the Sorcer X4 into a different circuit than the one that my system is plugged in to?

A: It should work fine, as a dedicated line will have slightly lower noise sometimes, in general it will still have a similar noise signature to the other lines in your home. What you want to avoid is plugging the unit into a power conditioner, that will greatly reduce it's effectiveness.

Q: Should I plug the Sorcer into my power conditioner?

A: NO! In fact, try just the Sorcer with no additional power conditioning. You may be surprised as what your power conditioner was hiding from you. Seriously though, plug the Sorcer right into the wall. It actually needs the unfiltered power to work it's best. As for the rest of your components, minimal to no power conditioning should be fine with the Sorcer working on the grid.

    The Sorcer X4 is way better

    Posted by Ken Basar on 7th Aug 2019

    ADD-Pwr Review This mini review is not only about the Sorcer 4 but also the great customer service from a well-known Audio dealer; The Tweek Geek. I was really curious about ADD-Pwr products. I own a Symphony Pro from a decade or more ago that works ok but... Now there are new products. I read a couple of the online reviews but I was not sure about spending $4000 for what I thought to be basically a tweak. (even with a money back guarantee). I contacted Mike from Tweek Geek and he had a demo unit that he was willing to send. In a few days the demo arrived but it was labeled Magnifi Tech. From what I learned this was an earlier iteration of the Sorcer. I must add that more dealers (like Tweek Geek) should provide demo units. Especially for those of us on the fence. I noticed some criticism on this thread that I would like to address first. The chassis appearance; it looks fine to me. Transformer hum? I cannot hear any conceivable hum from the unit. Looking at the insides there is no special crystals or magic paste inside. Just transformers, electronics and what appears to be settable digit settings. Well, since receiving the unit, I have been amazed by the change in my system sound quality. People, this is not a tweak but a huge system upgrade! Music takes on a very real personality. By that I mean it no longer sounds like a recording but actual live music! Vocals and instruments are so real sounding! There is a rightness to sound, call it analog, or organic but boy does my system sound good! I am 66 years old and a classic rock fan, I have listened to that music for decades. I can truly say that those familiar recording sound so much better, very resolved and very real. Hard to believe, mighty impressive! The Sorcer X4 is way better than any power conditioner, power cord, footers, room treatments that I have ever tried! And believe me I have tried many, many, so many… I noticed even more of an improvement than when I added the Audioquest Niagara 7000! BTW, I am using both products concurrently so perhaps there is synergy. I have been told that placement of the unit affects the way it performs. I just found a spot in the middle of my rack and plopped it there. Later, I may change its location, but I can’t imagine the sound getting anything better. I have it plugged into the same dedicated outlets (Furutech NCF) that my Niagara is plugged into. I also have a Synergistic Research grounding block plugged into that same quad box. So, I had to have one. I have placed an order for the Sorcer X4 and it is now in transit. I should get it sometime next week. In the meantime, I still have the demo to use. To all who read this, I’m not getting anything thing out of posting this information, just sharing my opinion. If you contact The Tweek Geek perhaps Mike will have me send the demo unit to you when I get my new one. ozzy
