That is super helpful. I will abstain from commenting on the brands I am unfamiliar with.
MSB would be a very good choice. It is a very natural sound and the discrete may not be the be all, end all in terms of detail, it is very, very good.
Bricasti would be an A+ Choice. I have spend time with the M3 and M1 SE. I am getting an M21 next when I clear a little inventory. If the jump from M1 SE to M21 is in-line with M3 to M1 SE, it belongs in your considered set at $16K.
One I have spent a lot of time with is the Rockna Wavedream Signature. It lists for $17K with XLRs. It is incredibly detailed and the sound is difficult to describe because it doesn't stand out in any way. I was expecting one to come in on trade but their is a risk that may not happen. I do not have a demo right now.
Finally, I would look at the Playback Designs Dream DAC. Like dCS, this DAC upscales everything but unlike dCS, it is very natural sounding and is not bright. This is definitely starting to drift up in price and lists for $22K though.
As long as you don't need an analog preamp stage all of these are very good options.
