Thanks dakken, I bookmarked that site. That JohnK guy was making me do logarithmic math for cripes sake! Kidding John, I appreciate the info and should have realized that you were referring to a single speaker. I'm embarrassed to admit that I can't follow your last round of calculations, although the logic makes sense. I'll have to dig up the reference you provided.
An update, I had problems with the NAS connection again, and since this time I'm pretty sure I am doing everything correctly, and I'm on the last day of the return window, I'm going to replace the Marantz.
