The room is 15'x20' with 9.5' ceilings. Not perfect ratio, but not far off. All plaster/lath construction, hardwood floor.
The sunfire is my current frustration in setting the room up. I'm using RCA in, and find that the gain is not easy to set correctly. Also, the built in amp shuts during quiet passages only to resume with and audible mild thump when volume returns.
Maybe this is all different if I run speaker level inputs? I'm tempted to open it and increase the off time delay, or just bypass it and wire an on/off switch.
System edited: HUGE upgrade, I bought a new place with a room I setup as dedicated listening room. I've added a dozen bass traps, and corner traps, and heavy padding under my favorite rug.
