I had the Revel F32 paired with a Primaluna Dialogue and felt they played well at medium to low levels, my room is also large, around 16x22. The Primaluna amps with Kt88's are known for there ability to drive all different types of speakers. The F30's are known for there great bass extension I would not be expecting the slam you could get out of a 300w solid state , but rather a more delicate/ articulate sound in the lower frequencies. I have been very pleased switching from solid state to tubes and feel the overall sonic benefit is much improved.
Good Luck
