Absolutely. Through the Hub, the app, and now they do sell
their own microphone.
This one is not easy.
The Focus 50 sounds phenomenal IMHO, as does the A700. Being more pragmatic, I do consider the integrated module amp and features of the Focus to be superior (both longevity and abilities to drive the speakers at higher SPL). While I do love Buchardt, their partnership with Platin is really a downside to me. Now, about the drivers, the ones in Focus are derived from the Evoke line, and of better quality than the SB Acoustics Buchardt uses. Yet... there's some 3700€ difference between both offerings, which is absolutely not negligeable. I would personally pick the A700 over the Focus 30, but the Focus 50 at the end of the day, is both were priced the same.
PS: From what I've heard, you still have to pay for Dirac license with Focus. That could be a better RoomEQ.
