I discovered this yesterday so I hope it helps those with the classic Naim CD player problem.... namely inability to find tracks with older CD players, particularly with the old style "top-hat" pucks.
This is generally caused by a) some manufacturers CD's being slightly thinner where the puck sits, and b) wear on, or flattening of, the rubber ring on the puck.
Solution --- Our good old friend - Blutak
Put a very small ( and I mean small) bit of Blutak inside the rubber ring - a small instrument screwdriver is deal for the purpose. Before fitting the puck to the CD squeeze the ring and the Blutak helps the puck keep the "rounder" shape, thereby improving contact.
The blutak doesn't move from the puck and is soft enough that excessive force is not exerted.
Donations for useful advice to........

Last week after trying to clean my pucks and transport for ages trying to get the CDS1 just to play a disk-ANY disk, I tried the very same bluetak stuffer that you describe, and it works a treat. If there is any miniscule degradation in quality, I havent noticed it, and it is far offset by the ability to play about any disk I choose. I should note that my transport hub is showing signs of wear with some silver colour showing through the black Nextel finish around the rim. Probably a result of years of having disks spin fruitlessly trying to be accessed. But inspite of this, the S1 can now play and access disks as well as it could when brand new. Oh, the two-ring puck works nowhere as well as stuffing the one-ring one.

Another thing no CD-player in the world likes is cigarette smoke. And as I never smoke less than 2 packs of Winston per day, I know what I am talking about
On my previous players (Denon, NAD) it was easy to clean the lens with a Q-tip and a little alcohol, and it took 10 minutes to fix it and to make it work for the next 2-3 years. Well, I daren't apply the same treatment to my Audiomeca, and even less to a Naim ... But keep in mind that if this is the reason of the problem, it is a very short intervention. So try to avoid getting ripped off

What is bluetak used for in everyday use so I can track some down?
It's some blue plasticine type stuff - kind of like plastic clay. It may come under a different trade name where you live.
Tend to use it for sticking up Christmas cards and decorations.

...or, you could threaten the CDS with a working copy of the Grease Soundtrack

I can play most CDs fine but I cannot jump around to nonconsecutive tracks on ANY disks. Have you seen this problem? Does the two-loop puck or the blutak treatment described above fix this problem?
I haven't been able to routinely randomly access tracks for at least two years- even with a 2-ringed puck. But with the blu-tak stuffing, the one-ringed puck can quickly access about any track on any disk at random.
I may have just put off the CDS2 upgrade by another few months :-)
