There are two ways to go with the Meridian 568 which I also use and I have explored the ways to add dvd-audio and sacd. One is to wait for the meridian modifications to the 568 expected later this year which will allow users to connect the meridian dvd-audio players, or buy the sony TAP 90000 es preamplifier that will allow you to run dvd-audio analog outputs directly through the sony, and you can still use the meridian 568, by running it through the sony bypass connections. The beset dvd-audio player to buy is the Pioneer D-47 and have it modified by Modwright
