In the $15k plus category, keep an eye on Nagra. Their successor to the Nagra Classic DAC will include streaming capability. Koch of Playback is on their digital design team. The analog stage is designed by the Nagra brain trust. Beautiful form factor if that matters to you and it will have that slightly warm and musical DSD sound if that appeals to you. I use their tube DAC which doesn’t have streaming and is quite a bit more expensive.
If the insightful and meaty analog quality of an MSB is also of interest, consider totaldac as well. It’s sold direct without dealer markup. If you configure it properly (PM me if you’re interested - the website is confusing to say the least), it’s killer and quite a bit cheaper than MSB even at the highest levels. Built in Roon endpoint is an option. But even their entry model is quite good. I have one.
