I have an Ayre Cx7MPe that I've always really loved the sound of. The whole "DACS are improving exponentially" stuff is way overblown IMO, so I recently sent it back to Ayre for a new transport. $400 and works like a charm once again.
Anybody purchasing a "new" player or transport needs to make sure the disc drive they have is either readily available or that the manufacturer has plenty in stock.
So bottom line, if you like the way the Meridian sounds, repair it.
