Cheap players may have more mains hum, in my experience,
but it's hard to make a general rule based on selling
If you are controlling the experiment with a computer, you
may find it a lot simpler to generate stimuli with the
sound card. You can use my Daqarta for Windows software
(free for signal generation uses) to generate signals in
real-time. It can produce a broad range of waveforms
(inlcuding arbitrary ones you define) and modulation types,
and you can create extremely complex signals by using
signals as modulators for other signals.
Let me know if you want advice about applying Daqarta to
your particular needs.
