$1000 (used ok) Streamer Dac recommendation please

Best deal I found for quality streaming for around a grand is the ProJect Stream Box S2 Ultra combined with the Pro-Ject Pre Box S2 Digital (DAC/Pre).  These need to be found pre-owned to be under a grand, otherwise they would cost about $1400 new.  I use these in my office system with great results. Best of luck in your search.

Chromecast Audio, cheap and easy pair with a MHDT DAC

agree with fuzztone that bluesound node (current or 2i) is a very good starter streamer/dac - streamer is quite good, dac is decent, but can certainly be bettered in terms of sound quality

others to consider used are innuos zen mini and auralic aries mini, both excellent values for the money for one box streamer+dac, cambridge makes a decent one too

Lindemann Limetree Network - Tidal connect, Spotify Connect, Deezer, Qobuz, High Res Audio, Bluetooth, Roon ready, Internet radio and podcast, USB for thumb drives, HDD and even lets you use a CD-ROM drive as a CD player through the USB input. Oh, WLAN & LAN and a headphone output.

Very well built, small form factor,, the reviews on the company site will describe it better than I can:

I have one and it’s brilliant for the price (around $1500 AUSD)

Best deal is the ProJect Stream Box S2 Ultra combined with the Pro-Ject Pre Box S2 Digital (DAC/Pre). 

Managed to find a used Pro-Ject Stream Box Ultra 2 for $530 in October incl postage.
