I'm listening both amplifiers, both are excellent but so different….
So specular that seems that the PROS of one chip appears to be the CONS of the other.

What you may like:

LME49860: <-----> LT1358:

LME49860: colorless and neutral <-----> LT1358: emotional, warm-toned and sweet
LME49860: accurate and clean <-----> LT1358: mellow and smoothing
LME49860: clear and unaggressive mids <-----> LT1358: forward and heavenly mid bass
LME49860: soft bass <-----> LT1358: punched and controlled bass
LME49860: airy and sharp high <-----> LT1358: polish at the high edges
LME49860: revealing on female voice <-----> LT1358: revealing on male voice

What you will not like:

LME49860:sometimes harsh-toned <-----> LT1358: sometimes muggy and confined soundstage
LME49860:flat and boring <-----> LT1358: lower resolution, higher distortion

Do you agree on my acoustical analysis?
interesting observations. For me it would be interesting to know, what happens, if one compare the same OP-AMP's in a RIAA-Phono Preamp with only one OP-AMP stage and a RIAA-Network in the feedback loop.

And? I'm still reading electronics literature written before I was born. I know ygg-it is still active.
