"... immediate impressions (Sorcer X4):  1. Climaxes wonderfully shattering without strain.   2. Humanness comes across more vividly.  3. Technicolor- like turning up the color on an old color tv set.  4. A velvet curtain appears and opens to reveal a new portal into the music.  5. Dynamics are robust and musically explosive.  6. Recordings previously unimpressive and not very listenable are transformed and now provide irresistible tonal beauty and engaging imaging.  7. Turn up the volume and get more of a great thing without any strain or compression. Pretty impressive list of impacts."

 -  David Sckolnik, a la carte productions

"The effect (Sorcer) is dramatic. It takes a flat plain and makes it more expansive. Things tend to sound more separate and individual with the edges' trails not blurred. Things seem wider left to right but not in an odd way. Deeper from front to back. It can be a bit overwhelming, it takes a renewed approach to mix with it, because that is what you get more of. Thank you!" 

-- Bernie Becker, Mastering engineer, Becker Mastering

"The  Sorcer brought a new level of focus in the imaging and warmth to my system. Moving it to different outlets in my studio allowed my to optimize its performance. I have yet to find a piece of gear that doesn't benefit from the effects of the Sorcer."            -- Gerhard Westphalen, Mastering Engineer, Westphalen Mastering

"Installed the second Sorcer X4. Improved sound just like you said (cumulative). Sound is more real  -  more natural. It sounds effortless and less distorted. More detail.  Lyrics are easier to understand (intelligibility). Sound stage is bigger. Thanks for inventing this stuff."  -- Chris S., Audiophile

"My congratulations on your Wizard conditioner. It is one of the very few true neutral conditioners on the market, and the reviews about it are very accurate proven by my ears. I didn't buy it because of the reviews but because I got one of your original Electraclear...for the last 20 years and it is still working accurately."                                      -- Edilberto Mir,  Audiophile

"In a nutshell, the Sorcer X4 conditioner transported me from an already wonderful, engaged and connected musical experience to one best described as an ear-opening mesmerizing musical experience.

The overall result is one of realism, naturalness, aliveness, sweetness, fullness, beauty, emotion, and connectivity. All to a greater degree than prior (to the Sorcer) AND much more significant when considered as a whole." -- David S., Audiophile

"What else did you expect? Installed 11 more eau2s today bringing the total to 17. Now every circuit has at least one. 

Biggest single improvement ever. Transformative!            Lower noise ( a lot lower). 

Lots more power at all frequencies.  Detail is revealed in the decay of instruments and voices. Greater clarity revealing more emotion in the singers and voices.

No congestion even during complex crescendos allowing the listener to discern individual instruments/voices even when they are in a crowd.

No gaps in the sound stage. Everything sounds more natural. The music "pulls you in." I could go on..."  -- C. Stevenson, Audiophile

Re: Sorcer X4: "My wife remarked unsolicited, a couple of times how good the TV screen looks... it is like a new TV.  Much higher definition, richer colors, and a brighter overall image. 

Musically, every system in our home sounds better, wider. There is more detail coming through.  I can see much deeper into the orchestra.  The image carries much more motion as the music move back and forth across the sound stage.  It comes alive visually in an astonishing way.  The sound stage is massive (taller, 

The music is far more dynamic.  

Crescendos come at you with exhilarating impact.  Soft passages are delicate and detailed. Instruments sound more like the real thing.  Violins sound more like the live experience.  Jazz ensembles are more in the room. Speakers disappear.  

Vocals, especially closely mic'ed female vocals are amazing.  They are more sensuous, more present, more three-dimensional."               -- B. Anderson, Audiophile

" At first, I didn't think I was actually hearing any improvements. Well, the real issue was I couldn't quite understand it or explain it. Over a week's time of brief one hour sessions in the evenings I finally got in the groove to describe it. Now I love it so much I want to figure out how I can get another one! Here's the bottom line: I was listening to my speakers before the Wizard. Now I listen to the music. Bass is better, depth is better, musicality is through the roof. And the music is relaxed. Wow. Can't believe how much more enjoyable my system is now. " -- Steve, Audiophile

"Can't get enough...

Well, forgive me but I'm just going to have to jump back in here and rant and rave some more about the impact this product has had on my primary system. I really had to force myself to quit last night, well past my bedtime. If I weren't hearing it for myself, I wouldn't have believed it. In nearly every case, the moment I start a new track on either CD or vinyl, from the very first note or instrumental sound I can hear an improvement in the timbre and character of the instrument, sound, or voice. Last night, I pulled out my CD of Dido: Life for Rent, which I hadn't played in a while. I was absolutely astonished by the realism, depth, spaciousness and overall quality of the presentation. I really don't even think we can call this a "tweak". It is, for me, a quantum leap in performance. This, when my system was already sounding very, very good. I believe this product can and will make any good stereo system much better. I almost feel like those of us sitting here using this product have an "unfair" advantage over those who are not. It makes things that much better. I'm also getting the sense that things are actually improved in my other systems by its installation-at least I believe so with my office system. ADD-Powr does state that the Wizard "changes the quality of the AC line from the entry point at the circuit breaker box of the home or commercial space". Perhaps this accounts for the apparent improvements in my other systems.

As I was listening last night to some CD's that I hadn't played perhaps in a little while-but not that long ago-I was attempting to account for any other factors that could explain why that particular CD could now be sounding that much better-and each time the only conclusion I could reach was: The Wizard.

I would add also another observation that a user mentioned in a review that I read. The increased emotion one experiences in the music is something you have to hear to understand. The reviewer described "an intense emotional connection". I believe this very much describes the experience, and it is hard to explain. The effect strains credibility...

However it actually works, I can tell you it works well. Very, very well.

Okay, that's enough ranting and raving....for now." 

-- Pete, Audiophile

"I picked up this guy about 6 months ago because of the high praise from owner of this unit here on Audiogon.

I started with the symphony Pro then to the X2 and finally to the X4. I plug into the outlet that my Bybee Stealth power conditioner is running off of, a Quantum science red outlet.

I then moved to the X2 and was shocked on the increased SQ the unit was doing to my system. It behaved like the SR PC SX I had but didn’t thin out the sound in any way like the SX. I sold the SR SX and bought the HB Design horizon passive power strip. I now had better SQ with this set up.

ADD-Powr hooked me up with the X4 with a trade in and now I was hooked for life.
😂😂😂😂😂😂 is what one does when you hook up this guy into your system. A drunken state of joy comes over you. You don’t need the audiophile lingo, terminologies , all you need to know is that you need to go out and get one whether it’s the X2 or the X4 and experience music as you’ve never heard it before in your system. A 30 day return is at the back end of this that you’ll never have to use because of the addiction this unit brings with it.

The foundation of your system will be high end with the ADD POWR X4 at the Helm of your rig. It made a bigger upgrade than any cable or component I’ve installed into my system.

I did unplug it a few weeks back and I lost so much Glory that I quickly plugged it back in." - "glory"    Audiophile  https://www.forum.audiogon.com

"Well this is my second unit and I am loving it. I tried one of the EAU4 units and it did not have any impact for me. So I tried a Wizard for more power and it worked very well. ... with the Wizard I am now listening to the music versus listening to the speakers and analyzing every note and instrument. I had room to accommodate another Wizard which was less expensive than going for a Sorcer. So now I have 2 Wizards on each end of the rack surrounding all the primary gear and it is stellar. The additive effect is stunning and I cannot find any other tweaks to make to the system except maybe further adjustment of the speakers themselves. The sound stage has layers front to back now and everything just sounds so natural and real I am playing everything I can pull up, even 10 year old playlists that paled to my newer ones are stunning. ...you've got to offer this to electronics manufacturers as an add-on device. This will change the way circuits are designed going forward. This technology made my year (already) and gives me the confidence that my system will sound good no matter what the rest of the room is doing. Amazing. Thanks." - "bugredmachine"   Audiophile      https://www.forum.audiogon.com

"Just received my eau2s. Holy @#$%! You weren't just blowing smoke with your advertised claims! These are easily the best upgrade I've tried...and I have tried many. Some offer very minor change.... maybe improvement, but not one has given such a monumental improvement in every aspect of listening. I put one in a quite modest second system and stood stunned by the immediate change! Dimensionality...check. the soundstage flew open...with layers! Background singers went from a jumble to individual voices. The sound of instruments is considerably more true. What was once a blur of sound is, now, separate. The VERY familiar discs used to test every change to my systems are NEW! Each is a different experience!" - Russ, Audiophile

"…. to quote myself once more….holy @#$%! Not only is the soundstage deeper and wider and more layered, it, now, wraps around me. I’ve never experienced such. Bass is better defined. With all the previously mentioned improvements, I think the best compliment I can offer to you and your products….the all-digital system sounds more analog….much more analog. 

Keep up your excellent work and, again, thanks!" -  Russ, Audiophile
