That actually appears to be a JFET-input version of a 4-BJT buffer that I posted here more than a year ago, only to discover that similar ideas were the subject of patents issued to Pioneer, Japan in the late '70s.

Would you dig that up (yr ago) and post it here? This can be the place to go to when exploring all such topologies and its variations and forms. Thx -RNM

The buffer which you posted a year ago is a copy of Pioneer 1980 SLC. I added something to SLC and reduce distortion 20+dB. The proper credit was given to SLC. I will be glad to give a credit to your circuit as well. Unfortunately Pioneer is 20 years ahead.
