Inexpensive Streamer for Office System

I don't think the Audio Note UK DAC 0.1x handles any resolution greater than 24 bit 48 kHz so you will need a streamer than can down convert high res material.

I do know that (e.g.) the Eversolo T8 can do this, but do look at the streamer's specs to ensure this capability (I do not believe that the Bluesound Node Nano supports downsampling). 

The T8 has a pretty good clock and if you ever upgraded the DAC the T8 is up to the task. My T8 feeds an Esoteric K-01XDSE.

The Audio Note UK DAC 0.1x was designed to optimize the sound of CDs.  I had an AN UK DAC back in the '90s and it was a great performer, especially considering its price, it actually made CDs sound like music unlike some DACs at many times the price.

Yes,  am aware of the DAC 0.1 x limitations.  Actually was planning on using the coaxial input if possible.  That was why I included the Metrum gear on my list.  If I do end up using the USB input will definitely find a streamer with good clock.  With respect to the downsampling, I was assuming Roon would do that as long as I set it up correctly in the settings.  If I had a bigger budget I was thinking of using the Wattson Audio digital streamer as it is coaxial output only.  In any event, I appreciate both your advice and your warnings!

Coaxial and AES, I use the latter. Only had it for a few weeks, it is in a separate system so no real sound comparisons have been done against my main rig, but what a quality piece of gear; works perfectly, easy to do firmware updates, has their own Wattson app that works very well if one doesn't want Roon endpoint or Qobuz/Tidal connect, or Audirvana etc. And like everything with a wall wort if you want to upgrade it spend as much as you like on an aftermarket power supply. Hard not to recommend it: Let me know if you have any other questions. Check out Han's review if you haven't already: https://www.youtube.com/watch?v=p-HeiVfAz4w

Thanks for your input.  I think the end game will be the Wattson, but not upfront.

op

you need a streamer with a good clock when you DO NOT use usb connection to the dac (usb lets the dac’s clock override, whereas for spdif connections the streamer's clock takes over...)
