I agree with @v-fi and would be very wary of buying a CD player that’s 15+ years old and would certainly check with Ayre first to see if especially things like the drive mechanism/laser can be replaced at reasonable cost if/when they fail. That said, the MP version is an excellent performer that probably holds up well even today, and here’s a review written by, um, me exactly 14 years ago!?! that might provide some helpful nuggets FWIW. Hope this helps at least somewhat, and best of luck.
