My problem was that I was getting some very annoying speaker hum and more specifically my subwoofer. It was getting to the point where I couldn't watch cable tv with my subwoofer on because it was just horrible. I started to do some research and read about power conditioning and was about to buy this $300 power conditioner just to get rid of the hum. I'm glad I didn't buy that power conditioner because this little thing fixed all my problems. No hum, cleaner picture (no rolling lines) and best of all it saved me $300. Highly recommend this product. Oh and if you have the onkyo sr705 and your reciever/speakers hum try this first before going onto the higher priced fixes.

5.0 out of 5 stars Affordable workaround for ground loop hum in audio/video system, February 4, 2007

I've got a coax cable coming into my house for analog cable TV and digital Internet. The cable goes to a splitter, and from there feeds into my a/v system as well as my cable modem. My computer feeds back into the a/v system via a mixer. There was no noise in my system's audio until the cable line was introduced. The cable company's technicians confirmed that both the cable and the house are exceptionally well grounded, but they couldn't figure out how to make the hum go away. Finally, after seeing a mention of the Dayton VIT-1 on a message board, I figured I'd give it a try. I put it on my line where it comes in, before the splitter, and it works just great. The ground hum has been attenuated to near zero, and the unit does not interfere with my Internet service or analog TV reception in any way. It is also quite affordable and arrived within days of my order. I recommend the VIT-1 to anyone who has ground loop noise with an analog cable TV line, assuming all other sources of noise have been ruled out.

After purchasing a new LCD HDTV, I was horrified when all of my cable channels had these annoying thick bars of discoloration slowly moving up the picture. I was even more horrified that the cable tech Comcast in AL dispatched told me there was nothing they could do about it. I almost bought this exact same part elsewhere for $40. Thank goodness I found this! I didn't realize how much my picture and audio were being ruined until I installed this! And for this price!? I would have gladly given $100! If you are suffering from a "60 Hz hum", you must get this. (The seller was really fast to ship it, too!)
