Can the ND 555 be powered by the
XPS or the XPS DR
Just to be different I’m wondering if that’s possible. I doubt it but I’m not afraid to ask 
If it was possible I’d like to hear what other people thought 
I quite like the idea of having the ND 555 and adding a better power supply when the funds permit. Pre-owned obviously there is just now way I could afford one from new.

It’s only 1 or 2 555ps that can be used.

As a rule I always read the manual for any potential kit I may purchase as manufacturers tend to make manuals available online.

These are so many questions where a couple of minutes research - reading the manual, asking Mr Google, looking at the manufacturer’s website, using the the Forum search - would give the answer. I guess it’s just easier to ask others to do the heavy lifting.

There are also so many questions where a simple helpful reply would be appropriate, rather than a snarky condescending response.

Indeed. The previous NDS could support multiple PSU options with the XPS (and XPS 5XS) being compatible (with the link plug in socket 2) as well as the one or two 555PS options.
No harm checking.

I thought so 
Ive always found people really helpful on here. The heavy lifting concept made me chuckle

I’m chuckling right there with ya on the “heavy lifting” 
Only dumb question is the one not asked; also, manuals don’t always have the answer.

Yep I was taught that very same thing
Why not consider nDAC/555PS combo instead, same chip, superb performance, or for you havimg a screen is a must?
There’s much more to the difference than just the screen

Please, can you share more, have you made a direct comparison? same conditions? nDAC is copy paste from the legendary CD555, right ? I would love to hear more.
They share the PCM1704K DAC chipset but from there on much is different, although both do have a discrete analogue output stage. The DAC white paper tells it better than I can;

The NDAC was not a copy and paste of the CD555 and certainly did not sound the same. There is more than just the Burr-Brown chip chosen to the sound of these things. Otherwise the CD555, NDAC, NDS and ND555 would all sound the same. They don’t.

So maybe I should consider the the Dac as an upgrade for my XPS NDX BT
How would that fair compared to the NDS
The ND555 is out of my budget 
The NDX 2 is a possibility but I’m only using iTunes lossless so the NDS could be just fine and it’s sounds like some people think it still sounds better. It would be interesting to here a response from anybody using the puritan 156 with the NDS, NDX 2 or the ND555
