In that thread there are also some nice pictures of the inside and some discussion about modding it (kramer5150 and some other people were talking about that)

Thought I'd bump this thread with a happy note

All is well in Entech-land. My 205.2 is back from repair and at the USPS. I'll pick it up tomorrow with a socketed OPA2107 in place of the 2134

. The stock 205.2 is a noticeable step up from my panasonic DVD player lineout by itself. I'm curious how much further the entech will scale up with the 2107.
Its not as straightforward as adding a socket and OP amp rolling. Its a sensitive circuit, (to put it in lamens terms) that runs on the brink of instability. I encountered some oscillation problems with using the 2107, that were beyond my meager troubleshooting skills. So, off it went

I'll post PCB pics tomorrow night, and muchos-thanks to the super-helpful member who fixed it for me.
