jafreeman,
i hit two weeks today and i am enjoying what i am hearing.
per your suggestion, i put the mat under the phono pre and the cards on the power conditioner, power supply, pre amp, and amp. treated the rca's, power cords, speaker cables, and electrical outlets with TC.
no big changes the first few days and then some moments, but overall felt it sounded a little louder and brighter than usual. this past weekend is when it really started to hit its stride. the stereo sounded more homogenized than ever. yesterday, i spun (lots) the double LP, derek and the dominos - layla, and i was genuinely blown away. it was like being in a whirlpool and i was being swirled deep into the album. easily the best i have ever heard it!
