Looking for best streamer without DAC under $3500


I currently run Metrum Ambre with Metrum Onyx and really enjoy it, but am looking to upgrade to a better streamer that has spotify among other aps. Currently looking at Lumin U1 mini, Auralic, etc.

Curious what others think

I was using the Auralic Aries G1 and then G2 with a Hugo TT2 and they were both great. I found it a bigger improvement than the mscaler. I have since upgraded to the dCS Bartok which I find better than the my old setup by a large margain. Also maybe look for a used dcs network bridge. 
Looks like everyone has forgotten the request of this post.
Apart from the Mytek Brooklyn mentioned, nothing above comes close to the iFi Audio PRO iDSD, a true "Swiss-Army knife" unit that sounds incredible. I put it up against many DACs listed above in a Pepsi-Challenge...well under your $3500 budget. Has a tube stage that can be bypassed, streams, wi-fi etc....but apart from all it sound incredible.
I own two as I have an ATC system in my office and a McIntosh system in my living room / main listening area.
We use and recommend Lumin network streamers. Besides being very high quality, the hardware and software is designed and built like a real high-end consumer electronics (CE) product similar to most other audio hardware people buy.
