I wanna learn about Naim CD players

Definitely check out the Naim forum.

One thing to consider about older Naim players is whether parts are available. I don't think you can get parts for the CD3.5 for example.

I used to have a CD5 which sounded great but those go for 6-700. They can be upgraded with an external power supply. Some people prefer the CD5 with a PS over newer CD5i or CD5i-2.

Last month i won ebay a used marantz Sa-8001 and then SA-8260, thought that would keep me busy for while. But then last night, at 2am, all of certain, the Rega Apollo popped up for $450 shipped. Not too bad right? I will get to a used Naim 1 day.

The SA-8001 is a fine machine, I own one.
