I'd guess one of them is pretty close to a perfect sine whereas the

other - obviously - is not.
Why not record and FFT them? If you can hear a difference in timbre,

the FFT spectrum should tell you why. If you can hit an FFT bin dead

center, you should get a single peak with a pure sine, and various

extra peaks with other waveforms.
