Buzzing in Exactpower SP15

I could go easily into a very long explanation. Trying to put it simply......

The Exactpower adjusts the voltage and power coming out of it going to your gear. Unfortunitely the quality of the voltage and power going into the Exactpower from the wall is taxing the ability of the of the SP15 to adjust the power.

Dedicated lines may solve the problem if you want to go that far. Or just don't plug the EP15 and SP15 into the same duplex.

Sugarbrie,
The SP15 A is Exact Power's Balanced Power product and does neither adjust voltage nor power. This is done by the EP15A, which stabilizes the incoming power and provides stable voltage at its outputs. I experience the same slight buzz with my SP15A, the SP15A being plugged into the EP15A. If I play music, I cannot hear this, however. A dedicated line does probably not solve the problem, as this is what e.g. I already have. Actually, I think that the buzz is simply the result of the natural work of the transformers of the SP15 A, which you hear bcs the unit is not islolated acoustically. From a musical point-of-view, however, the addition of this combo was one of the most noticable improvements I made in my system. I had the EP15 A first, then added the SP15A, although some said the SP15A would improve performance only marginally. Fortunateley, my experience proved to be different.

Howard, Every once in a while I experience the same with my EP. It's not audible through the system and has no affect on the music, it's just a physical/mechanical buzzing. And that's only on occassion.

I have discussed this with EP and they told me the cause may be due to DC offset on the lines. Soon, they will be releasing a small filter/correction device that is designed to be plugged into the same outlet as the EP. It will supposedly correct this condition. So obviously, it's not just us experiencing this problem.

Although, the EP does such an incredible job with everything else, I have learned to ignore it. Keep in mind, they are on the ground floor with these units. It seems that they are resolving any issues as they arise. I love my EP-15. And just to remind you of how much you love yours, unplug it, and go directly into the wall.

Suddenly the minor buzzing will become irrelevant.

My compliments to the boys at EP. They really did a great job with this unit.
