Ewww... assuming your input is a sine, your first harmonic is only
18dB down on the fundamental.  That's going to be quite awful.

(From reading your plot, input is 1.17V, first harmonic at 0.14V)

Does PSpice have a way to write to a WAV file, like LTSpice does?
Then you could do some listening tests.

Cheers,
Neil
