AudioControl is based on the Arcam, so the bugs will be similar, but slightly better as they do tweak the Arcam firmware. I have an Arcam and although the minor bugs can be frustrating, they are improving. I think Dirac Bass Control has a lot of promise and can be a real game changer. Otherwise, I agree Audyssey with the app is pretty good too.
In that price class I would recommend either the AV40 + external multi channel amp. Similar price point, but the amps with typical lifespan of decades will outlast a few processor upgrade cycles and pay for itself. ASR measurements have proven that processors do have cleaner (less distortion and noise) signals than AVR’s with preouts.
The Monoprice HTP-1 has fewer bugs, similar features and very good measurements from ASR. Street pricing of the AV40 is cheaper.
Another option is JBL Synthesis, also based on the Arcam with identical firmware. The price of the JBL includes the Dirac Bass Control add on (and potentially all other future Dirac add on’s) so it could be a better deal than the AVR30 + Dirac BC add on
