I would like to say that while the details and clarity are very apparent in the CA prototype, there is a also a mild congestion possibly in the upper mids region. It is more noticable with more involved, full music, ie. Prog or Rock, and less prevalent in acoustic or jazz. Particularly jazz that has a lot of air around the notes. Airy or open music sounds phenomenal.
The other area that could be improved upon is 8n the extension in the lower bass, sub bass region. The amount of sub bass is very similar to the FIBAE 3.
As to the driver count I couldn’t begin to say.
