Hi Dan,
Thanks for your advice to Jim. You are dead-on accurate on your recommendations. I just suggested the Sound & Vision Home Theatre Tune-Up DVD on a different post and it's invaluable when used with the Radio Shack SPL meter (get the analog version; the one with the digital LCD read-out is much harder to use).

By the way, the Sound & Vision magazine web site, where you can find out more, is not so obvious: it's www.soundandvisionmag.com.
