XPS DR or HICAP 2 DR

Which power supply upgrade will be the most effective, the purchase would be blind as the demo is not possible because there is no naim representative here and the unit has to be imported from another country. Advices would be much appreciated.

When I ran a NDX 2 with a SN 2 I found the XPS DR the upgrade with the most impact for the improvement on sound quality.

My ears, my room, my system.

Good luck with your decision.

A Hicap DR on your SN3 would benefit all your sources. A XPSDR would significantly improve your NDX2…

Get both :stuck_out_tongue_winking_eye:

The obvious answer is demo both and choose the one you prefer. Instinctively I’d get the XPSDR first of the two, but actually I’d get a pre-loved 555PS :grinning:

I have only NDX 2 connected to SN3, very expensive advice nevertheless :grin:.

Demo is not possible and even there is no market here for used naim equipment to buy, only option is to buy new and that too import from another country.

The XPS is the one to get.

The HiCap DR is the one to get first, followed with the XPS DR.

Buy what you can afford. Either will be good. Both will be better still.
2 Hicap DRs and XPSDR user here.

Aim to get both. The order probably is not so important… :grimacing:

Naim is all about Power Supplies… :slightly_smiling_face:

Whichever one you get first, you will eventually want the other one as well. I speak from experience. :smiley:

+1 for Xpsdr first

xps dr definitely, but by crikey i’d stretch for a 555 dr (which would outclass an xps dr and hicap dr by a mile, and save you a box!). Did it myself and it’s not a mullet, plus, future-proofing your source if ever you wanted to do an amp upgrade.

I went XPSDR for my NDX2 first, and then a year later got an HCDR for my SN3.

Inevitably you will end up with both.

So true. Vice versa for me, HCDR first then XPSDR

May I recommend skipping both steps and moving to an ND555 with dual power supplies and a 552/500?

Xps dr for sure every time

It probably doesn’t matter which way you go the end result will be the same.

Surely the S1 pre is the de rigueur suggestion these days :wink: ((with apologies to OP!)

So, I take it you’ve tried a 555ps with NDX2/supernait 3? You can argue either way - max-out source so you know what you’ve got amp-wise ( ie. ALL that it can do) and take it from there, or as you have done, use a ‘lesser’ source with better amplification. Which sounds best will be personal and future plans come into it as well. You obviously aren’t in the source first camp, which is just fine, but no need to sneer at other opinions. You just look like a tosser.
