Do anyone know what IC this is?

You really shouldn't put any ICs on a rug/carpet/paper, they will be damaged from static.

Thank you both. Good tip about the rug and static electricity, didn’t even think of that.
However this one is shorted. What can I use for a sub?

Pm sent, I have some ssm chips.

I have a few from AD and some from PMI who acquired SSM , they should be the same chip.

Just read the datasheet, thinking it would be an improved TL072 class Op Amp or something.

Boy was I impressed!!!! A Beast of a Line Driver, a substitute and much better balanced transformer output.
Definitely PRO use only.

THAT1646 and TI DRV134 are equivalents.
