@grateful_dad one thing to consider is that in your $5000 price range (and even above) it’s unlikely you will get a DAC with a built in preamp that will be better than a dedicated preamp. I would focus on a DAC first and not worry too much about the built in preamp. You have few choices, and just to name a few…
Benchmark DAC3 L or HGC (even has analog input)
PS Audio Direct Stream Digital DSD (a bargain now that a new model is anticipated)
Bricasti M3
You can get PS Audio and Bricasti with a built in network player that would eliminate the need for your Bluesound if you use Roon
