Brauser,
Yes, that's correct. In fact, a maker of Schumann devices suggested I try this. And he was right. You might want to give it a try yourself. I just put one side on top of the Schumann -- either side. But I will try both sides to see if this makes a difference. To do the A/B with the Acoustic Revive I used 2 copies of the same CD. No contest in favor of the Schumann.
I have 2 kinds of Schumanns. The SW1 used to be sold on Audiogon. I have 6. The second is a version of Schumanns with the Chartres coil. I have 2 of an earlier model and 2 of the latest model. I may start to market them. So, I don't want to give away too much at this point.
