Default Ground plane layout for phono pre

Hello,

I am about to build up a phono pre based on the Elektor design from '82 (see schematic).
I designed a board and I am a little unsure about the layout of the ground plane. Attached is a ground plane layout that is separated into input and "power" ground. Another optiom would be a closed ground plane without separated areas.

Any recommendations would be appreciated.

Best regards, Daniel
