hi, i have the opportunity to buy either of these speakers second hand from a friend of a friend but auditioning is a problem since he lives 250 miles from me. I know these speakers were in different price brackets when new, but he is offering them for the same price. All things being equal which should I go for? I'm veering towards the avi's because of the quality of their drivers - scanspeak/vifa, the apparent extremely natural and transparent midrange, and some reviews have mentioned them in the same breath as much more expensive equipment. Also, i'm not worried about quantity of bass just quality (and i have a sub), so it's more about the mid and top end. Cheers.
