Ron. LTSpice can input and output 16bit multichannel 96khz audio with interpolation through a virtual 32 bit precision digital/analog spice based circuit matrix of the users design. I'm not sure how you get more high fidelity than that =)

Sorry, I guess I was thinking of my cheap computer speakers. Obviously, you can route the audio to headphones, as you suggested.
I have used WAV files as sources for a simple sigma-delta codec simulation, saved the resulting reconstructed waveform as another WAV file, and then played back that file. It was only about 3 seconds of audio, because of the large amount of time and bits required to run the sim. An interesting experiment, nevertheless.
