IMHO, I'd start fresh with eye for capturing a presentation unlike that which I already enjoy. Given the spacial-rendering characteristics of the Ohms, maybe some horns and tubes? Maybe some analog?

You seem pretty handy, I'm sure a diy project would be rewarding and could be sort of custom tailored to fit your room.
