@pmotz ..."Yes there is some empty space, that is a design decision. Digital circuits need to be kept physically apart from analog circuits to minimize noise transfer."
Glad you pointed this out. Was thinking the same when I read some of the comments. Folks who understand at least the basics of design and best attempts at eliminating unnecessary noise can appreciate this. i.e. keeping the two parts isolated and apart from each other that is. Would have to listen to it for an extended period of time before determining if it’s worth the investment or not. 👍
