Is preamp's headphone output as good as "true" output?


I admit I'm being lazy here...   My setup wasn't designed well for accessing the rear panels of components. I want to make a WAV file from an LP, at good quality. The front panel of my adcom GTP-500 II preamp has a headphone output that has no volume control, so I'm wondering if I could send that signal to my computer for the conversion to digital. On the rear panel (if I go to the trouble to pull the component out), there's probably a pure, absolute output for such purposes, but is it different from the headphone output?
While I'm on the subject, any suggestions for a simple-enough and accurate conversion of the analog signal? I assume what I need is a PC app.

Thanks!

The output from the tape out will be a better cleaner purer signal than the headphone output as the headphone output almost certainly has an extra opamp in it to drive low impedance headphones with.

Yes just found it, your using an extra 45560 opamp on the headphone output.

The preamp headphone is the best to use it but I am getting the issue to connect with my Acer laptop. What should I do to resolve this issue? I also try on acer support for the help purpose but did not get any response.
