Mezmerize B1 Buffer Preamp

I have to wonder why one manufacturer would have a different pinout than another. This is a straightforward product. Reminds me of the pinout on an TI4136 chip. Same mess was made with an unusual pinout. Fortunately in that case, there are adapters available.
 
I thought I saw B1 buffer mono boards for sale one time. Just the buffer circuit with no PSU or relays etc.. Likely they were unofficial boards!

I have great interest in such a board for certain pre and integrated amp physical layouts.. I would power it with ubib.

Any info, thoughts or suggestions would be appreciated? I have diy front end boards but haven't implemented those. Maybe this is the solution and will produce the same subjective results as B1?
