I have an AVP and have wondered the same thing myself. There is a review at www.audioreview.com under Proceed AVP that is really a review of the Proceed AVP2. The person that wrote it had an AVP upgraded to an AVP2 and was very pleased with the results. It is a $2500 upgrade and some dealers may not be comfortable doing the work so you may have to send it back to Madrigal.
