[sdiy] Best AVAILABLE OTA for building new designs?

Except for noise floor in a mic amp with the gain wound up to maximum where there might be a very slight difference, I'll do the same for a 5532 and any of these fancy op-amps :-)

Of course there are op-amps which do sound different - the ones with added distortion.  Maybe the BA662 also adds something that way ?

If anyone can tell the difference between a BA662 and an LM13700 VCA in an honest double-blind test, I'll buy them the best Juno 6 I can find.

After they test clean for cocaine.
