Recommended streamers/servers?

A excellent dac+ streamer board is the Bricasti M3 
retail is $ 6500, give Perrotta consultants a call and ask Him what is his best price is , it has a lot of high quality  for the money 
and many excellent reviews.

When I tried a streamer server years ago, the Auralic sounded better than the Aurender and others. I decided to stop using USB because it just never sounded good, so I bought a very good dac with i2s and Ethernet and went with Roon and sounds better than any configuration before. I don’t like proprietary servers because of many reasons, a couple are: no built in backups, sometimes proprietary OS’s, how are you going to fix an issue if the OS update fails or server can’t boot???
I understand that some of these proprietary servers tweak their USB ports for audio, but since I won’t use usb and no server company has software that compares more favorable than Roon, then why use a proprietary server

I have the sonore ultra rendu via usb to audio gd dac. It is mainly a room player   Excellent sound but have to go to settings section to select an airplay emulation.  Need this for Amazon hd which I added later.  Miss the flexibility of bluos but sonically no interest in changing 

Try to get a used Emm Labs NS1. Best sounding streamer than any Innuos.

5k to stream? Wow! How bout 179 bucks! The Grace Link Digital Radio...check it out....
