This puppy has full descrete transistor output stages!

As if good op amps don't cost less than $0.50.

**Nope. I pay more than that for the AD825 (single OP
amp only). It is the best I've used.

Seen Nat Semi's recentish LME49710/20/40 ?

Obviously not.

However, I'd like to see the results of Trevor's evaluation of a chain of
the 5532 op amps that he has blacklisted. Here's the question - how many
stages of 5532 unity gain buffer, operating at a peak signal level of 2
volts, can we cascade before Trevor would reliably hear a differnce. I
suspect that after 100 stages, he might have a chance! For part 2, lets up
the stage gain to 10 dB, and then interpose attenuators between the stages,
so the levels throughout the chain and the output level are still 2 volts.
For parts 3 and 4, let's up the gain again to 20 dB, and finally 40 dB.

In none of the cases above will Trevor be able to hear a change due to just
one stage. Doesn't stop him from posturing dogmatically and foolishly,
though.
