By the way,

My G91a is not for sale anymore (I have not figured out how to remove the listing either here or on Audiogon). I did put it up thinking I would just use my 518 and 500cd for stereo play if I could get the 6000s working. This was premature on my part.

I will stay with this project. Hopefully, I can do it with the original D6000s from eBay, the DSP6000c, the G91a, and 2 analog rears. If not, the fruit of this thread will guide next steps.
