Better OP-07 type for audio?

>How about the OP-27?

The standard hi grade op-amp for measurement electronics. Bloody good,
bloody expensive. They do oscillate if you get one of the inputs close
to the supply rail. Probably only worthwhile in expos.

The OP-275 is a dual audio op-amp. Better than a 5532, with good drift
specs, negligible input current and lowish voltage offset, 1mV or so. I
like them as a very good TL072 replacement.

OPA2277 is a good dual OP-177 from Burr Brown. Again good for expos and
VCO CV summers.
