RE: Stereo Buffer with Parallel Connection Question

"are there any potential issues running the stereo buffers in this "summed parallel" mode"

Yes.

It's fine to feed both inputs with the same source but it's not OK to tie the two outputs together. That "shorts out" each of the two outputs.

The low output impedance of one stage is seen by the other and visa versa.

That low impedance is too low for the unit to properly drive.
