I have recently bought and installed a Monster Reference Power Center HTS3500. I am running a 811 and a 522 through this unit along with all my theater equipment. It has really given me a much clearer picture even in 480 mode and even better in in 1080i HD There is one problem though that I have noticed on one channel so far, chan 109 is that it will lose the signal and try to aquire again, if I turn on the 522 the picture comes right back in, turn it off and it goes away again?? Does any body have one of these unit and have you had a problem like this?
