Suggestion for $10K soup to nuts digital?

Start with Auralic… the Altair G series is exceptional as a Streamer/DAC

Bricasti M1 dac streamer has several Sonic filters, and R2R dac 3 separate linear power supplies , low noise regulation. Sounds excellent ,I would highly recommend a high quality Ethernet cable AQ Diamond is a very good choice 

Anthony at Perrotta consultants. Gives excellent service and good deal especially if you buy a cable from him and power cord AQ Thunder is very good 

check out the reviews , I own Bricasti myself and very very low noise and very natural sounding totally isolated from noise before the M1 dac .and you can probably Get both these $1k cables with the M1 for around your $10 k budget.

Lumin T2 (Used) or the Lumin T3 new! Lumin X1 crazy good and comes with an excellent power supply. Roon Ready. Great price on used one in link.
