Upgrading cd player

I thinking about upgrading my Rega Isis CDP. I’m thinking about the Audio Research Ref 9se or the McIntosh MCD1200. Can anyone give me any thoughts / options on this ? Also I heard that Audio Research stopped production on the Ref 9se due to not being able to get the lasers anymore / that Phillips stopped making them ? I would also rather stick to a one box unit than separates. Ty.  Also if anyone else can recommend anything also I would appreciate it. My budget is up at about 12k
