This is Joseph. Yes. It is because of the hardware limitation. The ROM size on the Classic units are smaller compared to mPower units. Also, because Classic units have a single-channel sound card built-in to the unit (mPower and PK units have dual-channel sound cards, which means that you can listen to media file and the speech at the same time.). I hope this information may help you.
