Used this to cut down on some hum to my sub amps from the integrated amp I was using. I recently upgraded amps and no longer have the hum issue. $199 retail. Very nice Jensen transformer inside. I did not notice a detrimental effect in system and it removed nearly all of my 60 Hz hum amazingly.

I used an ISO-Max in a previous system and it worked very well to eliminate hum with no noticeable (by ear) degradation in sound. Good luck with the sale.
