Mapleshade has very good advice on their website and they back it up with a money back guarantee. The low height and tilt back set-up has to do with the Allison Effect (floor boundry bass reinforcement) and time alignment (think Vandersteen or Thiel speakers). The brass footers and wood plinths drain internal vibrations keeping the sound clean. This is a win win if you try them out.
People often change/upgrade. They go from monitors to floor standing, floor standing to monitor, then to cone/planar/electrostatic, etc. What the guy did before, during, or after makes no difference because their room and equipment has nothing to do with your room and equipment. Also, the people who sell their stuff on the Gon seem to come out OK. It's what makes this a fun hobby.
