Not to be rude but a CDI maybe a little bit of overkill in that system and would likely drive him to want to upgrade sooner than he'd have expected... Certainly did in my case ... Maybe worth looking for a Naim CD3 or 3.5 although IMHO the 3 sounded better!
Pitty you've sold your Meridian 206 Shane. That would have been a fine player for your friends system!
