Hi, everyone, I recently bought a second-hand Naim CD5 cd player. I have only my computer speakers(with amp integrated) in my place. For testing it, I bought a DIN to 3.5mm jack lead and connected the player and the speakers with it. I found that, even I turned the speakers to the max volume, the sound of the music was still too low, even hardly to hear.

I tried to google for the reason, people say, cd players work fine with computer speakers, but no one mentions cd players with DIN ports.
Somebody knows is that a good cd player or not? I really need to find this out in case it is a faulty one, I have to return it.
Another question, I found this photo, which shows a device covered on the left two of the 3 din ports behind a Naim CD5. Does anybody know what is this for?

Thank you very much
