[sdiy] The sound of various Op-Amps

It seems like a lot of the newer opamps are optimized for their DC 
specs. And reach their optimum THD only on a relatively high load.
The 5532 and 5534s are very good when you have to drive 600ohm loads.

Just as with cars, there is no good-better-best for opamps IMO. It 
always comes down to find one that is best *for the job you're doing*!
And that search space is multidimensional.

Performance is relative.  A. Einstein :-)

Cheers,
  René
