gainclone chips in Parallel
Interesting way TI runs opa chips,wonder if this can be done with lm3875,lm3886,lower parts count,dont have to match gain of each chip with precision resistors,second chip runs at unity gain,any thoughts on this?

Nice ! It looks a bit like the TDA7293 parallel mode in the datasheet if I remember.
But LM chips are not stable at unity gain according to the datasheet
