natural sound want such a thing?
Some people dislike the sound of op-amps. Some op-amps try to correct
serious defects
in their design with lots of negative feedback. The class B output
stages in many op-amps
can have traces of crossover distortion products even after NFB. Some
op-amps can
be made to act as if they are "single ended" if you connect a resistor
from the output to
either a negative or a positive supply of DC of around 20V. The
resistor should draw
current thruout the entire audio waveform.
Those people who dislike the sound of an op-amp will hate nearly every
recording made since about 1980 or so. Mixing boards have many op-amps in
them as do many distribution amps. Personally, I will take a well designed
op-amp circuit over discrete components.
