Dac+Amp recommendation for streaming-only system


A couple years ago I bought supremely good speakers (Zu Audio Definition MK IV). I was supposed to replace my old amp and DAC at the same time, but life got in the way and moving countries a couple of times + having a kid put a dent in the plan. Now I finally have the time to get back to this.

I know absolutely nothing about hifi and brands etc, so here's my question:
What devices (amp and DAC, or if such a thing exists, something that has both) should I be looking at for a great streaming music experience? Basically the system needs to play either Spotify or Tidal and do it well. Nothing else is needed (well, I'll hook up my tv to it too, but that's it). Budget around 5k.

For the reference:
- My current system is Plinius 9200 + MHDT Havana Balanced + Argon2 streamer.

The Plinius is a good amplifier, but super impractical (especially love the "too quiet - WAY TOO LOUD" binary remote) so now would be a good time to replace it. However, if nothing better has materialized in my price range I can live with it. MHDT Havana, which was popular at the time, was a good match for my old speakers, but just sounds sloppy and lazy on the better speakers. Also, it's super old so something wayyyyy better must be out there. Argon2 doesn't do anything except provide an optical Spotify stream for the DAC.

- I prefer something "musical" which to me is neutral or slightly warm, dynamic, precise and not harsh. Daily music played on the system goes from super-well produced (metal, old-school rock) to produced-by-pressing-record-and-hoping-for-the-best (northern soul, punk) so terribly recorded music should still sound palatable.

- As I said, I know pretty much nothing about hifi. I just listen a lot of music, so I bought the bits and pieces after auditioning them (the Plinius test especially was fun, as a local store supplied half-a-dozen amps for comparison). Unfortunately I don't live near a good hifi-store right now, so testing is a bit more difficult and would be grateful for some tips on where to start with all this.

Thanks for the responses!

First of all, Bluesound Node seems perfect. I'll definitely get one of those.

On the amp+dac front I'm contemplating between two options.

First option would be to get a combination like a First Watt amplifier and a remote-controlled DAC (maybe Benchmark DAC3, I did some reading and apparently those sound pretty much perfectly neutral & I assume you kinda want a neutral source with these kind of amps). My logic here is that this combination would keep things fairly practical, while providing great sound.

Then there's the lower powered one-box solution. I'm not too keen on Lyngdorf because I actually own their room correction unit and know from experience it doesn't do much with my current listening room & speakers. However, I noticed that Devialet 120 gathered rave reviews 2 years ago but was replaced with a newer product recently. Side effect of this is that hifi-stores that ship to my area are basically giving away used 120s, could get one for almost nothing. It's not exactly super low power device, but a step down and also likely a very practical solution.

Currently I'm leaning towards the second option, mostly because it's closer to a "hit play on your cell phone and start listening" ideal. And with rest of the family using the set (at least sometimes) this is worth considering. Any thoughts on if I'm making some kind of a mistake here?

 
Depends on if you like the Devialet sound character as opposed to being heavily swayed by its obvious convenience factor. Choose what truly sounds best and most involving emotionally.

You may also want to consider the Auralic Polaris DAC,preamp,amp, and streamer one box solution.  I've owned their Altair DAC,preamp, streamer for about six months now and I'm very pleased with its performance.  Very easy to use and setup.
