Being since there is no perfect world, there will always be a compromise with any of the options you have listed.

I have a few questions to ask.

The first question I have is, what is the reason the equipment is in a different location that the Mitsu TV?

Is it because the equipment feeds another system upstairs?

How far away from the Mitsu TV is the rack? (wire length-wise)

And lastly, can you give us a makeup and details of the system or systems, how they are used/designed for use, and anything other information you may feel pertinant to the situation.

Normally, if one could SEE the setup, it would be easier to give suggestions. Thats why I ask for more details.
