Music streamer with no DAC and no storage?


I have an all digital Kii Three audio system (active speakers with DACS and amps) controlled by the Kii Controller fed by a KS Realization USB cable from my Mac PowerBook, with Shunyata Denali and Alpha power cords feeding the speakers.  I am looking for a top-notch streamer without a DAC (already built in to my speakers) and with no storage needed (I only stream from h-res streaming services in 24/44 - 24/192).  I would like to play the streaming services without my Mac computer, but don't need all the functions currently offered in the current all-purpose streamers.  Any ideas?

Lumin products are outstanding and are super easy to use with a great app.  I had the A-1 and recently upgraded to the X-1.  
I have a Simon audio moon mind 2. It has an excellent clock . Which to me is important for digital audio. You can use the WI-FI input or Ethernet. It’s a solid performer with out a dac.
LUMIN U1......I love mine.
SQ jump from McBook Pro was huge......I use AES/EBu to my Chord Dave and its amazing.

@thyname Depending on the DAC, Chromecast can sound as good as Auralic. There isn't an iota of difference on Chord DACs between streamers as they are essentially memory DACs.
