...were so encouraging it's scary. Thanks everyone!! I used two 2"x2" table matts for a quick experiment, placed as per Avguygeorge & Detlof above. Bingo! details have become more palpable, female voices (I tried contralto, and jazz) are now better outlined -- AND the stereo image is more focused. Standing up, however, still gives a slightly different "hue". I will experiment more during this w/e, and hope to get back to you with more...
