This is interesting in that I also have a 20' x 24' room with catherdaral cielings. I use the M80s and do play vinyl. The M80s work very well in this environment for vinyl. I think that if you stay with one of our floorstanding models this would be best unless you were thinking of a sub-woofer also. If possible for your budget I would look at the M60s or M80s. The big advantage to the M80s is that you will get more from your amplifier in what is a pretty big space to fill.
