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.

You can solve the Teac and Lumin's need for a wired connection with a $20 WiFi extender or if he is on Comcast they have their own extenders.  I have owned both units and prefer the Teac.
I had problems using the TEAC with a wireless client. I ended up running a wire to it. 
Worked fine for me since November 2018 with either a TP Link extender and now an Xfinity Xpod. 
When I had a Lumin the control app for Android devices did not work well at all.  I understand that it works well with Apple devices.
Lumin will requre a wired connection or a WiFi extender.

as for one box solutions:

Cambridge Audio has two streamer/dacs in your price range.
