Ground Plane or not ?
Designing this front-end for my amps has been harder then I planned. Part of the complexity is the time delays I need to add; my woodworking is not bad but it’s not excellent and decided I’d put the speakers front-aligned. This lead to having to delay frequencies so everything sounds right. Now, there’s no way I wanted to do all that in analog so a simple DSP system is in order !
In order to keep the design work to a minimum I decided to use power board from panson_hk on diyaudio; then I only need to make a front-end. This front end shall have DC Servos and DACs so keep the number of PCBs and complexities to a minimum.
All is good until…
Ground Planes or not
Here you can see Channel A has a ground plane and Channel B has a star ground; which is best and any ideas on optimizing the layout ?
