In case you weren't aware, I've been battling a nasty 60 cycle hum problem in my home theater system since purchasing a new refrigerator for my house. If you aren't aware of the background behind this, the original thread is here. Thanks to my new best friend Chu Gai who introduced me to the solution to this problem. The answer is a product called Hum Eliminator from Ebtech Audio. This is a multifunction unit sold in pro music stores for studios. As such it is transparrent and contains very high quality circuitry. (See web site for more information). I got three of the stereo version since I'm running a 5.1 channel configuration. The 8 channel rack mount version would have looked more impressive and a little cleaner, but would have been considerably more expensive. If and when I put a rear center or two in my system I will buy another one. I plugged these magic little boxes into my system between my preamp and power amp, and like magic all the hum dissapeared. Now I can listen to my SACD of Miles Davis' "Kind Of Blue" in peace! Let's all give Chu a round of applause!!!
