Yes XM all four feet are firmly planted on the shelf. The hum is definitely coming from inside the 7700. To the far right of the cabinet.
I do appreciate your advice about the volt meter and I intend to look into that as it might be the problem. A good friend of mine decided to go to Hawaii over the holidays and is retuning on the 8th. He has a volt meter.
Also the new processor I intend on purchasing is the main reason that I am not doing anything more aggressive at this time.

INPUT NEEDED ON....Processor. I am considering the Marantz 7701. I like everything about it. It does have a few more bells and whistle on it compared to the 7005 but not at a gouging price point. I can grab one for $1600 and trade in my Outlaw for $300...leaving me with a $1300.00 price tag.
Outlaw is selling the 7705 for $1200 plus shipping and they are out of stock.
No, I do not need this processor tomorrow but there is no mention about when or if Outlaw will be still offering the 7005.
Hmm maybe they will be upgrading to the 7701?
What would you consider to be the best move that I should make.

Thanks
