Dan,
I use a Proceed CDD with my MF A324 and they go along very well. I had the chance of comparing this CDD transport against others (Cal labs, modded Music Hall and others) and it blew them (albeit we tested them with an EAD 9000 DAC). I use a Kimber Illuminations D-60 digital coax cable. The CDD can be found quite cheap these days at the used market.
