Keep the Bluesound as your steamer. Get a better DAC, tons of options for $2k or less. The first thing you need to determine is what type of DAC implementation you want — R2R, chip (ESS, AKM, Burr Brown, FPGA, etc.), or tube-based.
For under 2k, Denafrips Pontus provides a great value for R2R DACS. That would be my top pick
I also have owned and liked Chord Qutest, Audio Mirror Tubadour III, and MHDT Orchid. Having said that, I recently bought a Denafrips Ares II for my home office and I must say it will stand up to many dacs around 2k. I’m shocked how much DAC you’re getting for $850.
