I first heard of this at the Magnan Audio Tweak site more than a year ago. Now I ran across the website, athttp://www.taddeo-loudspeaker.com/
This is a tweak that I haven't tried. You insert it between your DAC (surround processor if you're using its DACs, CD\\DVD player if you're using its internal DACs) and your pre-amp.
The science is way beyond me. Per the website, its probably not appropriate for my Theta Voyager DVD/LD/CD, which is based on the Pioneer, which already rolls off the highs some (but it sounds better!).
Would you believe that this company is in Rochester, N.Y., home of the famous AV Science and our phenom webmaster Dave, as well as the Chuck T gang. Anyone interested in visiting, scoping it out and trying it?
