The design is not intended to be comprehensive, for example the driver amps could be pulled into Class A with current sinks.
Sourcing suitable foil caps for the DC servo in the footprint shown is difficult but not impossible. Issues not examined are the precision required of resistors, gain, servo authority and pass frequency.

An externally hosted image should be here but it was not working when we last tested it.
Very nice work, counter!
When it comes to PCB design/layout, I think you're clearly on a whole different level than say the average DIYer here.🙂
Is this what you do for a day job or is it just a hobby for you?
Also, what type of software are you using?

Its star grounding for the signal grounds, yes. But you've used a groundfill for the power grounds so its a bit more complex overall than 'star grounding' - a hybrid grounding scheme perhaps?
