To answer an earlier questio, the sensitivity of the 703s is listed as 90db, but the CDM 7NTs have the same rating. The difference is the 3d driver in the 703s and a power rating of 50 - 200 watts into 8 ohms, as opposed to 50 - 150 watts into 8 ohms for the CDM 7s.

I have been searching the net and found some posts saying the 703s are relatively easy to drive and others saying they suck lots of power. But that is the way of the internet. Everything has fans, anti-fans and lots of people somewhere between; and it's hard to tell which among them actually know what they're talking about.

For me, the immediate question is, do I spring for a pair of M2200s while they're on sale, in hopes they will improve the sound? If that will work great, but if not I send the amps back.
