Comparing streamer/DACs between $5-10k


I’m looking for a DAC/Streamer single unit, willing to spend up to $7-8k & not opposed to something like a recent model/demo/open box unit.  The only streamer/DAC experience I’ve had so far with my gear connected is with an Aurender A200 on demo from a dealer. Said dealer says it’s the “benchmark” at this general price point.  IDK,  It sounds great, but what would I likely hear differently with the following units?
 

-Meitner MA3

-HiFi Rose 150b

-Lumin T3 or P1

-Bricasti

First, A big thank you to everyone for chiming in  on this purchase decision.  I now have a great combo of streamer (HiFi Rose 250A) + DAC (Denafrips venus2, 12th anniversary.).  Total cost to me was $4780.  I started with a strong consideration for a Aurender A200($6300+ tax). So glad I went with the combo of separates I did.  Sound quality I’m already enjoying from the Denafrips blows away the Aurender.  Not even close.  Even when I add the fancy cables (Cardas HS USB, AQ Ethernet) I’m well below what I would’ve paid alone for the A200 (without cables).  
 

*Another massive pleasant surprise is that the HiFi Rose app is brilliant!  Better than Conductor in every way with the exception that it doesn’t fade out of tracks you’re playing..
