hey Mrjstark... I auditioned both the monitor (218 be?) and the AC 10 Be. Upstream components were a Plinius preamp, a Cary 303 CD player using the solid state output at it's highest sampling rate, and a Cary CAD 120 amp in ultralinear mode. The monitor had big sound for a monitor, and altho the bass was prodigious, it felt forced and a bit boomy. The AC 10 be was actually less bass heavy, better integrated overall, and smoother up top, but still very revealing and detailed. It lost out to the Piega in imaging and overall musicality. The Piega was more musical, more cohesive, airier, and more detailed. All that and it's a much smaller speaker. The Usher was very nice, but it sounded a bit like a box, and somewhat congested. The Piega was really box free and even off axis sounded great. This was the TC 70x, not the CL series. Amazing for a retail price of $12K. Piegas I think are under-appreciated for what they do. I was floored.
