Thanks, Pepe. Those Infinitys do not sound like ass.
In my experience, every room has nodes. Yours exceeded 12 db at some frequencies, with over a 24 db swing between 40 and 100hz, and the lowest octave was weak. In my room, I have a hump exceeding 15 db at 50hz. The left and right channels are never the same. Higher ceilings help, as do very large rooms (both of which require more power).
If nothing else, it's fun to watch the dancing leds on the Rane, even with just a cup of coffee.
Happy New Year and good listening all.
