Balanced Audio PCB Layout Design

I already have the full Bill of Materials and a set of clear reference photos; what I still need is a production-ready PCB layout that ties everything together. Your task is to handle both the component placement and the complete routing of a balanced audio driver board that runs from a single 5 V input and generates ±12 V rails internally. There are no fixed dimensions, so you can choose whatever outline best supports clean signal paths and sensible power-ground separation. The only mandatory hardware interface is XLR—please keep the footprint orientation practical for panel mounting. Preferred deliverables • Editable design files in KiCad, Altium,—or another mainstream tool that supports Gerber export • Gerber, drill, pick-and-place, and centroid files ready for fabrication • A brief layout note highlighting impedance-critical traces, ground strategy, and any special considerations you took for minimizing noise I will review the first pass for fit and signal integrity, then we can iterate once if needed before sign-off.
