Sean this test/experiment was done over two years ago. From what I can remember most of the gain was in the 200 to 2500 hz range. We also did a pink noise test with the same methods and the Sistrum seemed to have a flatter in room response thru the mid bass on up into the midrange as stated. The graphs stored on the rta made for easy comparisons..The mic was set up at the best listening position for that particular system..Sean the Sistrum and Audiopoints are coupling devices and not isolation devices. I believe when placed under devices that Sistrum somehow helps in the alignment of electro-mechanical fields so they are less random and more focused. And because they are more properly aligned they are more efficient.. I believe this focus point is ground hence the coupling. Has anyone measured or tried to measure any gain in output or a change in response on devices that were cryo'd..Many brass players have stated that their saxophones and trumpets were easier to play and so much more lively after being cryo'd that they had to reduce their breathing levels by a third. Maybe Sistrum provides the same benefit..Tom
