Inexpensive Streamer for Office System

+1 Wiim Ultra but add a Teddy Pardo external LPS, all in for under $1K. That's all you need.

Check out Bluesound.  I have the N130 and it is an impressive little box that comes with some impressive features for the price.

i am quite familiar with the audio note dacs having had a couple

the 0.1x is an older model, from 2004-5 iirc - i suggest for these older units it is best to not use the antiquated usb input, use a modern streamer with a solid clock circuit instead... so for this application, if sonic purity is a priority, my suggestion is to use an auralic unit (aries, aries mini, aries g1 and so on)... they are relatively inexpensive now as the company is no more, but the lightning ds app is open source and works just fine, the units are built very well, a couple notches above the mass market cheapies... the femto level clocks in these units are superior to those in the cheapies as such as the node, wiim and so on and linear power supplies are already built in or integrated into the setups

just my 2 cents having been around p quortrup’s dacs extensively 

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!
