I had a room almost the same size in our prior home. I looked at a number of high end speakers including the Whisper. I finally settled on a set of Dunlavy SC-V(s) and have been a dedicated fan ever sense. What the speakers do best is play loud (or soft) with great authority and eliminates/reduces the acoustic challenges of almost any room. They are fast like an electrostatic but images as a true point source. They go extremely deep, but are very tight. They would match beautifully with the Fathoms and your other equipment. They must be purchased used and a vintage set will go for something around 5K. The potential in this room is AWESOME!!! Hope this helps.
