Although I've been using non-isolated version mostly, my recent experiments indicate that isolated version sounds smoother and less harsh. I would recommend isolated version and that's what I'm using from now.

You are also saving yourself a world of mounting concerns with the isolated.

on the other hand, you need a much larger heat sink with the insulated version

I wouldn't think so. The chip transfers less heat to the heatsing, when it's insulated

The heatsinks on your amp are good for 6 channel surround amp.
