DAC Streamer Recommendation


A client of mine purchased a home in Colorado which included for free two mid 1970's Klipschorn K-Horns in perfect shape.  I am helping him assemble a system for the K-Horns.   I have purchased for him so far a Luxman L590aii amp and a VPI Prime Scout turntable with a Dynavector MC cartridge.  Although vinyl will be his prime source, he would also like to have the capability to stream hi-rez digital from Amazon. If the budget is $2000 for a streamer DAC, new or used, what should I look at?

I am a vinyl and SACD guy so I know nothing of this product.  Thanks for your help.

The Lumin D2 is a good recommendation.  Also check out the TEAC NT-505, which is what I ended up getting after considering both, mostly because I got a good deal on the TEAC.  
Bluesound if you want to stream many different services.
Aurender, if you want to stream only High Def services-Qobuz and Tidal.

Do the Teac NT505 and the Lumin D2 both have wireless capability? The preamp features on the TEAC would not be used since he will have an integrated amp.  Does everyone use Roon software to run these things?
The teac only has a wired connection. You can use the Lumin, esoteric, or teac apps or bubbleupnp (Android)
If the primary source is vinyl and streaming is secondary I would simply go with a Node2i and use the BluOS app and onboard DAC. Connect it with RCA to the integrated. After he gets used to it try some separate DACs if he isn't satisfied.
