On meaurements FWIW, I've done crude measurements at the listening chair using the Stereophile test CD and a Radio Shack SPL meter. I've measured Omega 3xrs, KEF LS50s, Harbeth P3ESR's, Silverline Minuets and a couple models of smaller NHT's.
Much to my absolute surprise, the Omegas measured best in my room followed by the Silverlines. There's not a doubt in my mind that in an anechoic chamber, the Omegas would measure the worst and even I expected to see it in my setting.
Regardless, at the end of the day, I'll always choose based on my ears. As mentioned above, I really don't think, given current measurement techniques, that one could pick one speaker over another as being better in their room. Nothing beats listening to the candidates in your own room with your own equipment.
