My initial impressions of the ADD-Powr Sorcer X4 are posted here:

"I'm auditioning a Sorcer X2 now at our a/v studio, it's on the same circuit as a large format console and analog signal processing running off of balanced power. I've done quite a bit of testing in capturing mixes with and without the unit in place, with various cabling and so on.. would really value your subjective impression on how it's been performing vs. the Corelli.
the testing process here has resulted in a range of other holistic changes to the monitoring config & the overall result has been positive- it creates an unusual uniformity of response between components that can reduce phase-related anomalies in a larger system. as it's been noted elsewhere, the unit responds to changes in position, sequence with the other components, possibly time of day & amount of time it's been working. upside there is that it's "tuneable" with a little elbow grease (provided you have other outlets and cables to try.) potential issue is that it does add another layer of complexity to a system & potentially variables that may be tricky to control- too soon to say on this end.
our unit (actually a x4) has settled in after a few weeks worth of tweaking and experimentation. it's been very helpful in refining our monitoring chain and outboard config to help manage phase relationships and spatial positioning in our mix projects. the unit can simultaneously remove certain kinds of variances between one piece of gear and another- and make it a bit more apparent where other issues are coming from. very interesting effect hearing the way vintage analog components inter-relate on the sorcer's circuit- and of course, it's easily reversible by moving individual PSU's to a different electrical circuit (or simply shutting the unit off)
other key components currently on this circuit
MYTEK manhattan II
8 channel JCF tube converters
RME 6432 & 642 MADI-AES converters
BPT balanced power transformer
mostly wireworld IEC cables
Neve 8058 console
lots of harnesses and patch cables, analog outboard gear"

"We also listened with open minds...In a mastering studio. I was able to audition to the SorcerX4.
As I understand it: This device emits a low frequency (below 20Hz) pulse on your AC circuit as well as radiated through antenna-I think Nordost was doing a similar thing with their devices.
It does change the sound of audio being produced on the same AC circuit, but it is not a power conditioner...It is a harmonizer. It does change the sound, but that change is additive. These harmonics can can be seen on a spectrum analyzer like Izotope Ozone. If you like what it does, use it.
We are after the original source/signal...We prefer the processing to be done through the mastering chain, not our AC products-i.e. harmonic pulses that accumulate depending on how many transformers you are using - X2 vs X4
I feel using balanced power and quality passive power distribution is the best solution for A/V systems. Certainly open to what Garth Powell has developed at Audioquest too."
