Would a cost-reduced, no-options, preassembled version of the A12 (let's call it the A12b) for, say, $279 sway your decision? It will sound exactly like the current A12 and will retain the Grayhill, Bourns, and E-Switch controls, Cinemag transformers, and Neutrik XLR connectors. Add our bomb-proof, made in the USA chassis, 80W power supply (nearly twice the power per "slot" as a standard 500 series rack), and wiring harness for a total of $599 before shipping.
