I have an Orville Rev 2/3 and an H8000FW and they sounded slightly different. The Orville sounded more round and the H8000Fw more cristal. But every unit has its charm. If you plan to program with vsig be prepared to a lot of bugs in the Orville OS. The H8000 OS will be developed and becomes better, but the update schedule of eventide is very slow.
