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

Why. Not build your own machine for several reasons much higher parts quality 
such as a a Jcat Femto clock usb card, a Jcat net card, SS hard drives 
a external Linear power supply .fanless heatpipe case like Synology or other cases. Mojo Audio build hot rod - best name brand parts  to whatever you require
it could cost up to $4k . Ben at Mojo Audio  knows Digital very well his quality 
and sonics with dacs, and servers is very well known in the industry and have won many show awards. We have dissected several name brand streamers even at $4-5 grand + and average at best parts .I don’t see dual Femto clocks in  other
products at this price or parts quality even close .like Sparkos
Descreet opamps ,Vishay naked resistors.Mojo Audio without question build great Linear power supplies in all their products, no switch mode power supplies. look up Belleson Super regulators ,the best out there .a seperate linesr power supply is critical to get the best sound and isolates the bower supply from the sensitive digital section. Like seperates ,you can put more quality in it.
in my dac alone there is 9 Belleson regulators, very $$ In the powersupply ,plus Mundorf 4 pole capacitors. Made in USA 45 day return policy on mojo design    ,5 year warranty and modular,updatable  .apples to apples ,no dealer mark up,all the money is going into the build. Who else out there  offers this ? Nobody I know of .check them out .
Just James, Here's a suggestion. Keep the Metrum Ambre. There is an SD card  inside with Roon on it that can be changed to an SD card with one of many streaming programs or services.Take $3299.99 and buy a Sonnet Morpheus DAC. You will be blown away! This is the engineer/owner of Metrum's new company. (Cees Ruetenburg) A continuation of his R2R technology. Same I2S connection as Ambre. Then sell the Onyx and pocket the cash!
Me...I'm on the cheap side of things. If I was looking for something which is a pure streamer, I would probably go with a Zen Mini and add the power supply. Darko loved it......

For under $3.5k?  Easy, just get Node 2i for $500 and enjoy the $3k you save. Seriously. You need good user interface and functionality, such as ability to integrate with streaming services, external disk, user interface to play your selections. Like @rbstehno said, this is just a specialized computer. $3.5 is more than you'd pay for the newest full-featured MacBook Pro!
