ADD-POWR Sorcer X4 review by David Robinson / Positive Feedback:
https://positive-feedback.com/audio-discourse/impressions-from-an-editors-notebook-part-1-add-powr-s..."Cutting to the chase: Regardless of which of the four systems was in play over the past 8-10 months, the performance gains brought by the Sorcer X4 were immediately apparent. I heard greater detail in every source that I tried, both analog and digital. Dynamics were improved, and the noise floor dropped. Even with other system enhancements in the listening room, there was an additional performance gain that brings to mind the emphasis that some mean when they speak of “a greater blackness” in their systems…a loss of noise, and an improvement in the SNR.
It was as if the entire listening environment in our listening room had been brought into a greater harmony, resulting in greater relaxation while listening, and a smoother path to connecting emotionally with the music. A new effortlessness, and a natural ease, made the experience with the ADD-POWR unit really desirable. And the result was confirmed on four different audio systems of unquestionable virtue. Every time, the Sorcer X4 made its presence…and the absences that its presence brought…quite obvious. Don’t think so? Try removing it from your system…."
