Hi all, I’m new here and recently been purchasing some classic Naim gear. Got myself some mint sbls and recently got the CDs mark 2 with xps.
Simply stunned by the results. I want to check something with you all.
Couple points that might be completely normal and probably me being pedantic.
The puck doesn’t quite perfectly centralise on the spindle so it’s slightly off centre when spinning
The spindle that the puck snaps to looks worn to me and almost as if there is a something missing like a washer, again it’s probably fine.
Picture attached
Spoke the original and only owner of the CDS and he said its always been that way since day 1. it does seem odd to me, as if you move the puck about whilst its located it grinds off tiny metal particles, so surely this cannot be correct? it must have had a cap on it.
i have managed to order a wheel from the mechanism only from a very helpful & knowledgable person @ quickcycle. just google it as not allowed to add links here.
is it just a case of gently prying off the existing wheel from the motor spindle shaft. i see that the existing wheel has slots in it that i assume there to gently prise off the wheel.
The plating on the magnet ring has flaked off, leaving the ferrous magnet material exposed & wearing down.
The picture above that Richard posted has had a CDM12.4 platter transplant for this exact reason.
You have to be very careful when removing the old platter - the VAM1205 is normally very well glued on, sometimes the entire motor shaft pulls out with it & then you’re really screwed. I would normally cut the platter from the edge through to the spindle once the magnet ring has been removed. Brutal & not for the faint hearted, necessitating removal of the transport from the tray.
Setting the height of the replacement platter is also critical for lens focus.
Not a job I would recommend taking on if you aren’t confident!
I very much doubt it’s straightforward, and that’s without even touching on getting the suspension set up right, but anyway, that’s a discussion that falls outside of forum rules.
I bought a second hand CDS 2 around 2002 and traded it in 2021. The metal spindle looked the same as the poster’s photo from when I purchased it. It worked perfectly for 19 years or so. I am not sure it is worth trying to repair. I presume it was a manufacturing problem. I did notice that the puck didn’t always centre first time but I just had to repeat until it was centered. It always sounded very good so my advice would be to leave well alone.
Kind of thinking the same tbh. It works absolutely fine and even if the puck doesn’t centre correct it doesn’t affect the performance unless anyone else can say it needs to central?
What I found worked best was rather than placing the puck I let it drop from a few mm’s above the spindle and gravity seemed to help with a central placement! I never detected any sound problems if the puck wasn’t perfectly centered.
