Thanks Cobraman...I had the opportunity to travel to Legacy again last week and hang out to listen to a brand new pair that had been built the days preceding my visit and was able to observe Bill dialing them in. Of all the Legacy speakers I've owned since 2005 (there have been a LOT), the AERIS amazes me with its ability to sound good right off the line (literally). I've also been able to hear a pair late last year that had 200 hours on them and can tell you break in like anything else I've owned will make a difference. Given the various levels I've heard (day1, 50 hours or so, 200 hours), my gut tells me that these speakers will 'come out' at 350-500 hours extremely strong and impressive. The best part is, they already sound great on day1! Please let us know how your break in results come in and what you are hearing. I agree with you about the AMT and the new midrange and midbass drivers. They are all something special. The thing that stands out the most is the integrity, sound profile and accuracy to real-life instruments that the mids and highs on this speaker render. You can really hear the differences between different metals (for cymbals, guitar and bass strings, etc...) and other materials (drum heads, pipe organ metal versus wooden/reed pipes, etc....In addition, based upon hearing the Aeris dialed in on 2 different occasions, I can tell you the AMT tweeter assembly appears to never show a harsh edge; you can keep throwing more level at it and it does not ever seem to distort,...all you get is more detail. This is an extreme rarity even in the best speakers I've heard. If first impressions (or third and fourth also in my case) are accurate, and break-in simply reveals and refines more about what it can do and how it does it, the AERIS is to me one hell of a speaker and an entrant at a reasonable price that should make some pricier manufacturers sit up, take notice and get very nervous (IMHO).
