I have a CD3 and was reading about mods on a DIY’er board here in the states and a couple of their posters mentioned using a FlatCap power supply with the CD3. As far as I know that’s not possible, but perhaps I’m mistaken. I’ve always sort of regretted not getting the 3.5 CDP for this very reason, even though the CD3 is highly regarded in its own right.
Welcome. Addition of power supply not possible with cd3. It only has an output, no inputs. You correctly identify that the 3.5 could use a power supply.
That is correct, the original CD3 had no option to upgrade with an external PSU. Unlike the CD3-5, which could be used with any Naim PSU with a 5 pin DIN powered output socket.
I have a bit of a soft spot for the Naim players with the “swing arm” lasers (CDM4 & 9). There is just something very pleasing about the way they operate.
