Mr D,

Radio Shack currently has a sale going on on the analog SPL meters. There on for $30 right now until they are out of stock. Not every RS will have these though.....

Second, i own Monitor Audio Siver 5i's and they sound absolutely fantastic for music and movies. There is absolutely no muddled sound whatsoever, everything is detailed, crips and clear. How do you have your Silver 3's set-up? How far away from the wall are they when installed on your mounts? What height are they from the floor? Are they toed in?
