I did a little research on the subject you were speaking of regarding the Philips CDM4 transport used in the Jay’s Audio transport. Unfortunately that transport is no longer in production.Definately a reason not to blow $2200 on it. Get the $600aud Cambridge CXC transport, and you can get a new laser from the corner shop for $40 should you ever need one.
