The Music Ring


MR800/1200                                     MR1800/2400

What's a Music Ring?
The Music Ring is a balanced power line conditioner and distribution center.  Unlike most line conditioners currently available it addresses the primary problem of noise in your AC by taking the unbalanced power available at the wall receptacle and converting it to balanced power.

At this point a brief explanation of balanced power is probably appropriate.  In a normal unbalanced power line you have a hot conductor(120V to ground),  a neutral conductor(0V to ground) and the ground. This unbalanced configuration permits low level noise contamination to pass through the power line directly to your sensitive audio components.  In the Music Ring the 120V to ground is converted to two 60V to ground. These 60V signals are 180 degrees out of phase with one another. You still have 120V, 60hz available at the outlet receptacles but the noise has been cancelled out  by common mode rejection.


"I received the unit on Monday morning. It worked out of the box. I am still in the evaluation process. Early listening, I give it a pretty good score for its price against some of the more expensive line conditioners that I have used. Definitely better than the Chang CLS 1000 ($1,000) and definitely better than the Hydra Shunyata that I have ($2,400)."

The Music Ring's effect on music is dramatic. If we could only make one recommendation to audiophiles it would be to listen to their current system with balanced power before considering another upgrade. "You haven't heard what your system is capable of until you have plugged it into a Music Ring."
