Pmotz,
I'm actually working with Rives on my room (I'm in the process of building out the Rives design) and yes, he recommends the 4jrs, but I liked the Gallos better. My room is 13' X 15'6" and the speakers are "on" the long wall--speakers to listening position is about 7 feet.
Xenithon,
Please keep us posted on the SA--I wrote back & forth to Gallo just about 3 weeks ago and they were completely mum--no comment on production, no commitment to any design or date.
