Hi Lynne,
What is relevant is the maximum amount of current that is demanded by the audio system. As long as a 15A rating would provide a reasonable amount of margin with respect to that demand (and I suspect that it will in your case, assuming that you will not be using a powered sub), there is no problem using a 15A conditioner on a 20A line.
Best regards,
