Default Some advice on chipamp grounding

Hello community,

I'm building a My Ref rev c chipamp using home etched boards following this layout offered by udailey: http://www.diyaudio.com/forums/chip-...ml#post1681700

All is good but im having a bit of a difficulty wrapping my head around the grounding scheme. Since im not really doing monoblocks, the default grounding scheme of the layout kind of makes me confused . The output ground wiring to the PSU comes from the fact that they're wired with the speaker protection circuit that shares its ground with the PSU ground bus. The amp ground connection is also default on the layout.

Following the "monoblock-type-layout" i got to the plan posted here in the attachments.

Would there be a better alternative to this that any of you can think of?
