Perfectionist,
You are more than welcome to come listen to the RM-X at my house in NE Scottsdale (just south of Shea Blvd at 130th St, near the Mayo Clinic).
I upgraded to the RM-X from the RM-40 late last year. The RM-X is better in every way than the RM-40, as it should be given the substantially higher price, but there is certainly a close family resemblence.
My room is well treated (fiberglass panels on the front wall and front half of the side walls, quarter round bass traps in each corner, heavy drapery fabric over all walls) and my front end, amplification, and cables are up to task. The speakers have all the options, including TRT crossover caps, lambswool stuffing behind the midrange array, and vitrified high compliance passive radiators. So, you should be able to hear VMPS at its best. The only thing I still need to do is get Big B out here to fine tune things...
