I hesitate to enter this discussion as it is very complex and component dependent. I have tried more than 35 various ac filters and conditioners and like only several, but I know that my findings may be limited to my SET/horn system. I have found the Sound Application Linestage is best at cleaning up your ac and making the sound very fast and dynamic. I have also found the Equi=Techs keep back EMF, especially from digital units, from muddying everything else. I plug it into the Sound Application. I know there are other balanced units to compete with the Equi=Techs, but I know of no one's experience that would cause me to change.
I have also found the Reimyo filter on my Reimyo amp adds greatly to the sound stage and quiet of the amp. The Reimyo is plugged into the Sound Application. My Citation 7.1 woofer amp likes only the Sound Application.
Good ac cords on each of these and after each of these adds immeasurably to their quality. I use Omega Mikros, Harmonix, FMS, and Bogdans.
