I have the CS Port IME-1 and never tried any other product. As I have posted in other threads the CS Port IME-1 works amazingly well in my system. Living in SoCal static electricity and dust is huge problem due to dry climate and Santa Ana winds. The ultimate test for the IME-1 was during recent winds that were almost hurricane force. The IME-1 worked beyond all my expectations. Before when I would change sides it would sound and feel like the album was attached to the platter with velcro. With the IME-1 nothing, silence. I turn it on when I power up my TT and off when I'm done playing albums. As far as any noise or impact on SQ, none, but the IME-1 not on the same circuit as my system.
