In my experience, if you need good quality sound from a PC (no matter the brand or size/shape) you will need to either upgrade the internal soundcard or use an external soundcard as your audio source. There are some nice USB-soundcards that provide very clean audio for around the $100-mark. If your source is going to be CD I'd probably steer clear of the $40 models - again you'd probably get the best bang for the buck from a PC with an external USB-soundcard. - Neil On Jan 27, 2010, at 9:02 AM, Bob Masta wrote: > On 27 Jan 2010 at 7:49, Monita Chatterjee wrote: > >> Dear List, >> >> We have a need for a CD player to play audio files (6 >> kHz BW) for an OAE experiment.
