I'm sure you could fit 3 or 4 systems in there, but I would only have 1. I would think you could take the sum of the money from 2 systems and make 1 system that is better than either system for all your listening needs. IOW, take the funds necessary for a SET amp + SS amp and get a better/higher power SET or better/class A SS amp (or just better in either case). Same with speakers.
I have a 12' x 13' x 9' room, and I tried Maggie 12s, 1.6s, Martin Logan Ascents in there, and it wasn't until I put smaller speakers in my room that I stopped fighting the room. But others have had success with putting those size speakers in similar rooms. 2 rigs in there is too much, IMO. But...
