Upgrading my blusound streamer

Take a look at the Innous Zen mk3. They have several models at various price points. I’m sure you can find one that meets your needs. 

Yes the Innous will be in line with the quality of the rest of your system. Check the reviews. One of the best!

On the streamer side, SOtM sMS-200 Neo or 200 Ultra seem to be some of the best out there.

I have the sMS-200 Neo, and it's a great unit. I have it hooked up to a Pro-Ject Box S2 Digital DAC, and it works really well. You could use your C47 as a DAC for now and upgrade to another DAC later.

I just got my PS Audio DirectStream DAC with Bridge II. The Bridge II adds the streaming part to that DAC. I've only used a a little bit so can't quite compare yet, but if the difference is minimal, I'm returning it and will keep my current setup.

And Roon of course, highly suggest using Roon if you want to use Tidal, Qobuz and some of your own music files through one system!

Preslisa64 one thing to do is switch to a good SPDIF Coaxial digital cable and don’t use the optical as its limited to 24/96 resolution. To get hires and 24/192 files you need coaxial. 

Naim NDX2 is said to be a really good streamer although expensive. See if you can listen to it somewhere.

Then you have Lumin and Aurender.
