My CDS3 makes a ominous rattle when I load a CD and lower the lid. Sometimes it takes 2 or 3 trys to get it to play the CD. It sounds OK, but I’m concerned about what may happen if it gets worse. The CDS3 was serviced 6 years ago and the transport replaced with a VAM 1202.
I had a similar problem with a CDS2 when the suspension became misaligned.
It was rectified by inserting the transit screws (which lifts the mech off the suspension), then removing the screws slowly, at the same time, keeping the mech level, which will reseat the mech on the suspension.
I’ve found with my CD3.5 the three small rubber rings in the puck compress. Get a pair of tweezers and rotate these round a quarter turn. If you have it, also give the rubber a wipe with some iso-propyl alcohol to clean the surface.
Longer term, I don’t leave a CD in the player and I rest the puck on a shelf when not in use so the rubber recovers from the compression - I don’t leave it on the drive mechanism.
Thank you all for your replies and suggestions. I’ve boxed up the CDS3 and sent it off to NAIM in hopes that they can fix it. I hope they can, I’ve come to be quite fond of it. But when I took it to my local Hi-Fi “dealer” to ship it off, I made the mistake of asking if I could listen to a 252 to see how it sounds against my 282, they said “sure, and we just got in a refurbished 300DR that might sound pretty good too”. So, while I wait for my beloved CDS3 to be fixed, I’ve traded up from my 250DR / 282 / HiCap DR to a 252 Supercap DR / 300DR. So far it’s been the most significant improvement I’ve made in my 25 year slippery NAIM slope. And my friendly “dealer” said, why don’t you just take this entry level ND5 XS2 home to tide you over while the CDS3 is in the shop". It sounds pretty good too!
I had the CD platter hairline crack issue on my CDX2.2 from 2016. This is obviously a problem and so bought a relatively expensive Chinese mech and pulled off the platter. I put this platter onto the spindle and all is now well. Perhaps Naim could commission a new platter?
