Hey everyone--first time poster so please forgive me if I'm putting this in the wrong forum.

I'm having a problem with a buzzing sound coming out of my speakers.

Here is the chain that my signal is going through:

Marantz 2270 Receiver (acting as a preamp) --> Yamaha EQ-70 Equalizer --> Antique Sound Lab Wave Amplifiers --> B&W DM602S2 Speakers. I've got my Sony DVP-NS755V SACD/DVD Player plugged into the Aux RCA ports on the Marantz. Everything is connected together using Van Den Hul interconnects. I'm also using an Adcom AC enhancer.

This setup sounds really good, and up to this point, there is no buzzing. Now, my Sony SACD Player doubles as both a CD and DVD player. My goal is to be able to use this setup so I can listen to music and DVD-audio fpr when I'm watching a DVD. There inlies the problem. As soon as I plug my Sony Television's Component Video inputs into the Sony DVP-NS755V's Component Video outputs, I start hearing a loud buzzing sound out of the speakers. It doesn't matter if all three Component cables are plugged in, or just one...it can be any of the three plugged in, and it makes the buzzing sound. This is just baffling me because it's a video signal and has nothing to do with the audio anyway! The television doesn't even have to be on...if my TV is plugged into the DVD player, I get buzzing.

I have tried a few things to get rid of it with no luck...I tried eliminating the EQ, different interconnects, plugging the television into the same power strip as the stereo, into a whole different wall-outlet altogether, etc etc. NOTHING WORKS!!!

Anyone have some idea of what's happening and how I can fix it? I'd really appreciate it!
