That's a very vague description. The CD format is just a 16bit/44.1KHz PCM audio format. If their requirements is just that, then all you need is a 10 year old SB16 or better. What you need to know is the features and specs they need, features such as input/output options, software/hardware compatibility, etc, and specs such as signal to noise ratio, THD, frequency response, jitter, etc...
