Naim CD5x versus CDX2

Personally, I would rather listen to a CD5x/flatcap than a solo CDX2. With Naim, the power supplies really flesh out the sound, like going from regular tv to hd. But - the CDX2 with the XPS2 is absolutely in a different league. Once you add that power supply, the CDX2 absolutely transforms, IMO. So I would buy the CDX2 if I knew I was later going to add the XPS. Not that it sounds bad by itself and I guess some might even prefer it to the 5x/flatcap. I just added this because I didn't think the above posters were emphasizing the very big difference between the CD5x/FC and the CDX2/XPS2. I see you have a x-03. Are you considering giving that up for the Naim player?

I would have agree with Chayro, tho not by personal experience.
I have previously spent some time on the Naim forum. Some users actually upgraded to the PS555, then to the CD555. A few went from CD555/PS555, then to an additional PS555!!
They all seem to agree that the Power Supply quality is a very important contributing factor within the Naim CD line.

On the subject of power supplies, I remember one review where the listener(s) found that the CDX2 with the 555PS sounded superior (whatever that means)to the much more pricey CDS3 with the XPS2 power supply. One more option is the CD5x with a HiCap, which gives the little 5x tremendous bottom end drive. I personally felt the flatcap worked better for me, but it is something to consider if you can.

Holy ancient thread resurrection, Batman!
