I still use an original CDS2 and prefer it for SQ to a CDS3 or any CD player without a silly price - a bit LP12-y but not lacking in detail or clarity or grip.
When it dies, I may well get a CD transport (Audiolab?) to feed my NDX2/ XPS2 or get a second-hand Core to rip my existing CDs and any CDs that I do get (I already have one instead of a CD player in Tasmania).
In any event, the CDS2 is still a great machine and many now have a mechanism that was replaced in the last 20 years.
Others have had very little use in the last few years (put into an attic in about 2000 perhaps) and may well be good for several years - making current low prices (some close to £1000) not bad even if a buyer doesn’t get another decade out of one. I might not risk that, but a cheap CDS2 with a mech from 2015, as recently advertised, would be compelling.
I also saw this thread:
Perhaps @Alto can be persuaded to sell one of his hoarded spare mechs?
