Equi=Tech Son of Q

Son of Q 1.5R. MSRP: $3,050

Original Owner. This 15A, 1500W, 12-outlet balanced power conditioner has been “on the floor”, bottom of my setup since new, in a constant “on” position without issue. It’s moved once with me. It is heavy. If you’re not familiar with the features and benefits of 120V balanced power please see below. I’ve taken a front photo however as it’s in use, I’m also including a factory set of photos as I’m presently using this in my stereo setup: DVP/SACD, Monoblocks, Preamp, DAC and Phono Stage and TT.  Asking $1900 including shipping to continental U.S..

Detailed Operation:
More than a power strip, less than a power regenerator (though not less effective), the Son of Q power conditioner from Equi=Tech offers a clever, yet simple solution to cleaning up your dirty mains. Designed for 15A/120V circuits, the Son of Q provides 10 outlets — 4 general purpose, 4 filtered for digital electronics, and 2 unswitched ground fault protected outlets. In addition, an easily replaceable surge protection circuit (rated @ 240 joules) and a cable TV line isolator circuit round out the features. Son of a Q’s output capacity is rated at 1500VA with a continuous current rating of 12.5 amps. The unit comes in a 2U cabinet, weighs in at a hefty 60 lbs., and is available in either a black or silver finish.

THEORY OF OPERATION: Without going into hyper-detail, a balance power conditioner takes the standard 120 volt AC signal (measured 120V to ground 0V) and, using a special transformer, converts it to a plus (+) and minus (-) 60V AC signal. You still have a 120 volt potential across the line (+60V to -60V), but now the circulating currents from the +60V and -60V windings are opposing one another as they flow into the grounded center tap of the transformer. Each of these opposing currents carry the same noise and distortion characteristics as the original 120V AC signal, but now, those noise components are 180 degrees out-of-phase. When the two opposing currents meet at the center tap, the noise components of the signal cancel each other out in a process known as common mode rejection.

TRANSLATION: You lower the noise floor of your system by an average of 15-20 decibels. This may not sound like much, but the effects are HUGE!
