Currently have Marantz CD63 KI & PM66KI. Just been given Cryrus DAD7 & III both with PXR's ! (Generous father is upgrading !!) Have DSPE800 as processor & cinema 7 spkrs. HK DVD25 & Sharp XVZ90E proj. REL sub on the way. Currently using PM66KI as extra amp for centre channel -using pre-out of DSPE800. Now have spare CD & do not actually need amp as the DSPE800 has centre channel amp. Any advice for upgrade ? Is it worth selling CD/AMP - in their day excellent machines but things have moved on tons and I have no idea of their value now? Would appreciate any advice.
