ivrobinson,
My reference to the Revel's being an "accurate" speaker refers to the type of sound it has, very flat and lifeless when I have heard it. You ask then can an inaccurate speaker sound good? That depends, how are you measuring?
Take the Revel and the Vandy 5A, both have a measured frequency response of about +-2 dbs from the 30-20,000 hz range when tested by quasi-anechoic means, and are by all means "accurate" speakers. Sit down and listen to them and you will hear two very different sounding speakers. Even variations of a couple of db's can significantly change how a speaker sound. Now add into that driver construction (different materials create their own sounds and resonances), phase response, and dispersion characteristics, and you can have two speakers that appear nearly identical on paper, but are far different in practice.
Measurements give us an idea of what a product sounds like, but we don't understand all the parameters that make up what we hear. The measurements are a good starting point. Speak with any audio designer (speakers included) and they will tell you subjective listening and voicing is a key factor in their designing of the product.
If you believe that measurements tell you everything, you should immediately run out and buy the cheapest CD/DVD player you can get, a cheap 100 watt receiver, and find the flattest measuring speakers that you can. It will save you a fortune and under that standard you will have a great system. For the rest of us, we found out a long time ago that one amplifier that puts out only .01% distortion can sound entirely different than another.
