Hi @Adikt
I see you’re having fun contemplating next steps and mapping out a future vision of a higher system, etc.
If you have an idea of where you wish to go, personally, I’m not convinced that it matters so much how you get there. In other words, with an end goal in mind, add things as you find them in the SH market.
With that idea or an approach, in mind, here are a few thoughts to share. ( In no particular order).
Now that you have a HiCap, adding a NAC282 pre-amp becomes a viable option.
Honestly, a 282 works fine with a SN ( in power amp mode), as a combo. And it’s a nice step up from SN only. Then take your time and see how you like that. We considered the power amp in our SN3 as maybe the star in that integrated package. ( Maybe a better power amp, than the pre amp section).
A next step might involve swapping the SN for a power amp. The obvious candidate would be a NAP250 DR. Which is another really nice step forward. However, in our case, we decided to shift the power amp into an active speaker “amp packs” instead and thought this was better outcome for SQ. ( Note : there are many benefits to active speakers, affecting the presentation and sound quality. But it’s maybe not for everyone).
Source first is always a good strategy.
Adding a psu to the ND5 XS2 → nDAC will be rewarding. If it’s helpful, there are lots of experiences of this idea shared. The search function is your friend. The key aspect of this option is the money involved as it presents as maybe lower budget and cost effective, (albeit you end up with 3 boxes).
However, if box count is a consideration, can see how a two box solution may be attractive, say NDX2 + XPS DR.
Maybe the key here is the cost of an NDX2 - for you locally - and then calculations for 2 box solutions v 3 box solutions. But, honestly, there not much on SQ to choice between those two options, maybe other than slight nuisances of presentation.
Users - including myself - usually pursue the 3 box option because it gets you to a same similar space for a lot less dollar.
So make a choice based on budgets, box count and your personal preferences here.
For speakers, looking at the PMC active options, maybe pursue the idea suggested by HH, namely finding a SH Twenty5.23i or 24i and then add the active upgrade modules as another step later. (Maybe trading the SN for PMC active modules ). The 23i’s are a more popular model, so maybe more likely to see these on the SH market. The 24i’s are larger, need a larger room and have a reputation for maybe be challenging in some room settings. So, would be more compelled to try 24i’s in my own listening space before deciding on that option.
Having heard previous generations of PMC, yes, the current twenty5 series floor standers are an evolution, more of everything. Once you move over to the active version, the step forward in SQ is compelling.
Another thought, there an argument for swapping all the OC parts - you currently have - for NC option NSC222, which is an attractive option as explained by others, no problem. However, If you are focussed on SQ as a priority, can confirm that ND5 XS2 → nDAC + psu → 282 + HiCap DR beats a 222. So, if considering NC as an option - from where you are - unfortunately 333 + 332 ( both bare, no psu) is the way to go.
Lastly, just to explain, we ran SN3 as pre-amp only, at home, for a short period - with PMC 23i active speakers. This is another pleasing step forward, compared to say SN3 integrated → PMC 23i passive. So, that’s another option, as a step in a planned mapped out progression.
Ideally, you might find a supportive dealer that allows you to explore some or all of these ideas before purchasing anything.
Hope all those thoughts help
Lots of options. Maybe too many ? Good luck.
As always, enjoy the journey.
