How did you determine that the LZ1AQ amplifier is not a differential amp?
the diagrams lead me to believe that it has differential inputs. Page 29
shows the specification item 10 which states that the inputs are balanced.
What

thanks again for the link

Thanks, Jim, that's opened out the discussion very well for me. I am not able
to determine how bad this makes the performance, since

What am I missing, where should I be looking?

The LZ1AQ amplifier is NOT a differential input amp, rather it is referenced to
ground.
This can have significant issues as it relates to common mode noise.
As a result of my research, I ended up with a Pixel loop. The amp has great
characteristics, differential input, uses an A.C. wallwart

What configuration did you use on your lz1aq loop?
