Default B1 layout question

Looking at the B1 pcb layout, why this a bit odd groundplane? Why the odd pads for the smoothing caps C1 and C2? Why are all four holes connected to the chassis and signal ground?

Any story behind this besides "it sounds better"?

I noticed also that the commercial B1 has an even more odd pcb layout. Why these squares?

Hi P-A,

I remember well Wayne's reply some years ago, why he used hatched ground planes instead of solid ground planes in the XOno. His reply was along the lines of, he just prefers the looks.

I guess there's not always a sacred secret behind every detail. In audio a lot works well, as it's not critical like for RF-stuff, but you of course know that.

Have fun, Hannes

Doing things for looks is always OK if it won't be in the way for the performance. Personally I think it's good to think RF. To achieve RF immunity is always good.
