Just finished 3 monitor gigs with AMP and not only did it perform flawlessly (other than me doing a GUI edit midshow that went wrong - although no loss of audio, and my other remote stayed perfectly intact and in control), the bands were all very impressed by the stage sound. Something I haven't been hearing lately from SAC (mostly because of the latency I would guess). Same rig, same system, same stage. Only thing is going from 2x64 on SAC to 0x64 on AMP.
Got the interest of another national act touring guy that also used to be a SAC user years ago and dumped it. Seems like the interest is there for the proper product.
