Heard the dual AHBs in the center spot this afternoon and hadn't seen this post before going over to Bob's house. I can't speak to what Bob heard off-axis but what I heard on-axis was pretty spectacular. His bi-amp arrangement is indeed a step up from what I heard a couple of weeks ago. We went through some of what we listened to previously and I'm even more impressed with the soundstage specificity and the rendering of instruments. I finally heard why Charlie Watts tried to buy Muscle Shoals Sound's Neumann U-87 after they recorded Wild Horses. Single mic high and in front of his kit and it snapped. No other drum mics - from the story I read in SOS - they weren't really expecting the Stones to show up. Part of it is the mic but a part of it is the house and it was all there.
We did drive 'em into earbleed territory with Ramblin' Gamblin' Man from Bob Seger's Live Bullet album - I was trying to see if I could feel the Hammond B3/Leslie combo like I felt it all those years ago at Memorial Auditorium when he opened for BTO and I left after three songs into BTO's set - he was that much better. Felt the bass but couldn't summon the air from the Hammond and the clipping lights were starting to dance with no sign of strain. Backed it down to just below clipping threshold which was still plenty loud.
My ears were certainly impressed.
I will also say that they push plenty of volume as monoblocks but the sound was not as precise as the bi-amp setup. We both like the bi-amp setup better.
