Very true! I agree with Scott 1000% on this. When I auditioned speakers, I took some studio discs that I play the hell out of (my favorite being disc 4 of the "Tougher Than Tough" Jamacian reggae box set - the dancehall disc) and some major-label released live discs. I used the Dick's Picks 9 set from MSG as my live reference because it sounds great, I had just been there for the Phish NYE shows, and because I could listen to see if the speakers could accurately capture the ambience of the room. MSG has a unique sound as a concert arena, probably because of that wooden ceiling, and the B&Ws I chose did the best with jazz music (what I listen to a lot) and also "put me in the building" at MSG.
