Network streamer recommendation without a dac/amp (pure streamer), under $4k

No optical, but another lesser known option is the magna mano streamer. If you've got an i2s input on your dac, it's one of the few ways to get that output option (same i2s configuration as ps audio uses). 

Thanks for the thoughts guys. Going to keep thinking about it.

One thing I like about simaudio and bryston is their long warranties, 10 and 5 years respectively.

Lumin and Aries are both around 2 years only. But I feel like they probably make the better streamers. I like the full colour display on the auralic but of course its not that important since im using roon my pc. From what I read a U1 out does the G2.. and a local dealer said they would take a trade of my Aria 948 speakers + $2700 usd for them. Or a straight trade no cash for the U1 mini. I do want to sell my speakers and this might be a good way to do it.

I have the Bryston BDP-2 with upgraded board that I bought used on Agon about 18 months ago for $1400. It's been very reliable and sounds great. I'm using it as a Roon endpoint connected with a wired Ethernet. AES/EBU connection to my Schiit Yggdrasil DAC. 

Jaytor thats what I want to do! :D

May I ask what is the serial number on your unit? I am considering a bdp2 now but I don't know if it has the upgraded board.

The previous owner updated the sound card after purchase. The original board used a white circuit board. You can ask the seller to open the top and tell you the color of the sound card. This sits on top of the motherboard and connects to S/PDIF, etc digital output connectors.
