1. QC: That should not be a concern. All parts are high quality. If a problem arises, just call VMPS and Brian Cheney will mail you new drivers or whatever is necessary. He mailed me a new driver for my STR-SE with no hesitation.
2. Cabinetry: One reason VMPS speakers are half the price of comparable models is that their cabinetry is simpler and less elegant. Cheney is much more concerned with sound than appearance. However, the oak veneer on mine has been quite durable over the last 8 years.
3. Sound: I auditioned the more expensive FF-3 SRE, whose drivers are same as RM-40, except with 6 ribbon midrange segments instead of 4, a much more rigid cabinet, and biamping. The midrange clarity and effortlessness of the ribbons (classical music) vastly surpassed anything I've ever heard. On the FF-3 that clarity and effortlessness extends down to the lowest bass, but I can't vouch for the RM-40. The only shortcoming I heard was a subtle roughness in the upper treble handled by the dome-shaped spiral ribbon tweeters, but I doubt this would be noticeable with non-classical music.
