For the most part, you don't want transformer isolation unless you plan on using balanced lines.  There are worse things than ground loops out there, and lifting a coax shield away from ground is a great way to find all of them.

You definitely don't want 10.7 MHz IF transformers, unless you are just trying to build a thermometer.
