[sdiy] The sound of various Op-Amps

[harrybissell]

They aren't the same thing, but they are two sides of the same coin.
I don't see how you would have high G/BW without fast slew rate...
or fast slew rate without high G/BW product.  Maybe for some special
purpose buffer opamps you might have fast slew and not too large G/BW
(since you are setting gain =1)

I think if you look for a high G/BW product, you will not find one without

a high slew rate...  or your bandwidth will NOT be good.
