StereoTimes Review: PowerCell 10 UEF & FEQ-PowerCell Equalizer and Element CTS Digital AC Cord

Clearly the best Power Conditioner we have ever used in our showroom.  If you have reasonable power it is my first choice is SERIOUSLY better power and sound and video if it applies.


StereoTime’s Mike Girardi reviews the new Synergistic Research PowerCell 10 UEF, FEQ PowerCell EQ and Element CTS Digital power cords.   Highlights from Mike Girardi’s review: “I knew within the first 10 seconds something extraordinary occurred in my system when listening to the first first track… Cheryl Crow’s voice had a greater clarity and presence while being more true to a live performance on each cut with the PC 10 UEF installed”


“…compared to the design of many other power conditioners in the market place which contain transformers, chokes, etc. in the conductor signal path, the EM Cell acts passively to condition alternating current with differential EM fields resulting in an AC power conditioner that is non-current limiting”
