Try plugging your office system into your computer to start. (I assume you have a computer in your office.) If you have a laptop or desktop, you should have at least USB out. The MacBook 3.5mm connection doubles as optical out. And a windows desktop may have USB, optical, and coax outputs. You may have options.
I recommend trying the free trials for Tidal, Qobuz, and Amazon high res. By the time you've exhausted the free trials, Spotify may have released it's CD quality tier. Spotify was far superior in its user interface when I ran my experiment. I currently use Qobuz for it's sound quality, but I'll be switching back to Spotify as soon as that CD quality tier launches. I used Spotify for about a 5-year period. The curated and rotating playlists, ability to discover new music, content layout, and access to content makes it the best. I find that Qobuz routinely lacks content I want to hear and doesn't help me to find the content I'd like to discover.
Also, there's a social media element to Spotify. When you want to share songs with friends and family and you send them a link, the recipient is most likely to have Spotify account.
