It looks like you have settled on what you want to do but, I was in a similar boat to you last year but went in a slightly different direction. I went with a Dac v1 and a nap 200dr and some revel m106’s with the plan to add a “better” pre amp if i feel the need in the future. For the longest time I looked at the 272 and or the uniti series and to be honest and this is the same with any brand (apple, sony whoever), all in ones in the long term are just not worth it, something goes wrong you’ve lost the lot either for repair or at the very worst if out of warranty and can’t be repaired for some reason becomes a giant paperweight. Not to mention your relying apps for control and i certainly dot like that! not at this price point. I personally like to keep things somewhat separate. Just my opinion and mean no disrespect to anybody that have and use these devices.
Personally, that v1 will take some beating and you’ll be spending a lot to do so. I actually think you’ll be surprised how far it can be pushed (despite what some say) even using more revelling amps. Especially being used as a line level source into a nac. And if the speakers are somewhat easy to drive (which they are) a nap 200DR will do just fine, You’re not going to notice a vast difference between the 2 (250dr). I’ve compared both and some will say its night and day but it isn’t, amps aren’t where the major sound differences lay, but! The 250dr will have a larger volume sweat spot and take on even bigger and harder to drive speakers in the future.
In your case, a 200DR or 250DR will give your speakers a very nice lift! It won’t be in the way you’re expecting, you probably won’t notice much difference till the wick is turned up. I feel expectations need to be managed a little. It’s not as if your going from one brand to another the sound is not going to change, Naim’s house sound will still be present your speakers just won’t feel so choked in turn improving sound quality that’s the difference.
I’m not entirely sure what you want to achieve you either want to stream or add more power? you can have both but what do you want to achieve first?
First step either way is add a raspberry pi to your V1, Allo digi sig, mac mini or intel nuc (with audirvana installed) or similar Sorry sounds better than anything I’ve heard up to around 3-4k mark and so much cheaper and more user configurable
In regards to set up
I think if I were in your situation id either look to getting a 202 and 200 (vastly cheaper if bought second hand or you manage to get some good deals at the dealers which im sure they could do ) and using the v1 as lineout source with more connectivity to boot. I’d certainly do this over any uniti series and if you really wont to stop using the pre section of the V1
Or simply add a 200/dr god knows why people think this a bad amp. Seems to be the fashion to just suggest the 250 or just jump over the 200dr. It’s highly underrated, id gives it a good audition before you spend the extra 1600 over it to see what you’re actually going to achieve. Think you’ll be suprised what the V1 can do here in this situation.
Or simply add a Supenait 2 and if your feeling really flush add a hi cap to it for a little more than the nova
A really left field option and you want some serious refinement and control and want to lower the box count right down. Trade in your speakers as well and get some ATC actives using your V1 as a source with some XLR -din leads. job done for the same price as buying the Nova if not a lot cheaper with the trade in
In your case, my top pic would be the supernait, v1, hi cap then if you want to add some legacy componets you can
Sorry for the long reply but just didn’t want to say buy this! its great!
