Re: op-amps with wide open-loop bandwidth ?

Oops, "unity" isn't what I meant. I mean, I want
any op-amp that is flat (more or less) to 20Khz
I'm not looking for any specific specs beyond that,
so it's V/mv gain curve isn't so important as long as
long as it's reasonable to 20KHz also

I'm simply looking for a wide variety of op-amp types
for sonic evaluation. IOW, I'm attempting to correlate
what my ear hears with with the variations in specs
from one op-amp to another and sadly deficient
in the list of op-amps I've evaluated so far are any
that are flat open-loop to 20Khz or higher. The best
I have on hand are 10KHz.

So far my short list of star performers via the
old golden ear test are;
THS4022, THS4052, THS4062, THS4012,
AD828, LT1363

Although it should be mentioned that these are
for guitar amplifiers and that Audio Hi-Fi enthusiasts
might not agree about the merits of the afore mentioned.

When you wrap the op-amp with resistors to get a finite gain, the resistors only determine the circuit gain as long as the op-amp gain by itself is well in excess of the design circuit gain. ...
