[sdiy] Op amp slew in audio circuits - sims vs. real life

[Justin Owen]

A general question...

I'm assuming most of us throw the TL072 or similar at most of our audio circuit op-amp requirements right?

Can any of you give some examples of where you specified an op amp with better/faster slew specs because standard op-amps weren't fast enough?

Asking because I'm working on a pulse output circuit (frequency up to 20KHz) that I'd like to shave every last µSec out of in order to get the sharpest response - but I'd also like a reality check on how much to worry about the slew and slight imperfections I'm seeing in sim (using Universal Op Amp 2) and how that will translate to real life.

Yes, at some point I will breadboard/protoboard it - just be good to get a general consensus before that.

Ta!
