Good morning! Such a question: there will be an increase in quality if you buy XPS to NDX2. Or will the addition of a power supply bring no improvement? And is such a connection even possible? Or still tighten your belt and buy XPS DR?

Yep, tighten your belt, suck it up and get the XPS DR. When mine went in, it never went out again until I came across a used 555PS. The XPS DR is a very good upgrade to the NDX2, assuming the rest of the system is up to it.


Get the DR. This is the clever tech that goes a long way to providing a low noise/stable/flat DC supply. Helped by a oversized transformer and modest capacitance. I say modest as compared to the 555psu it’s small. And for an ndx2, what likely makes the difference that most can hear between the two.


Thanks! About what I expected.)))

You can always buy a second hand XPS and have it upgraded to DR spec by Naim.

  • Unfortunately , it is not possible to do this in our country, Russia! I have already tried to update SuperCap)))
