Music streamer with no DAC and no storage?

@ecat026 also you can play around with the LUMIN mobile app before purchasing a unit. The only thing that won't work is choosing a target device or setting preferences for a device.

We ended deciding to carry LUMIN based on the quality and design of their hardware and software, after trying a few other options.

jeenam70  's suggestion of the Bluesound Node2 is an excellent recommendation.

New they are $399 (were 499, but now that the Node 2i is out they 2's are 100 less)

Also, not only do they seem bulletproof as far as having any issues, they are also kept in house by Roon.  They are Roon certified, and MQA enabled and tested.  And the Roon/Tidal combo is the most organized way, and user friendly way to not only keep track of your Music and Meta data, 

it is also an incredible way to expand your music exposure, because the bio's shared on Roon let you see every artist , your artist has played with.

Bluesound node 2 or 2 i is a great , reasonable price , streamer that connects to a network in less than 30 minutes.

@tatyana69  have been using Bluesound for the past 3 years but while sonically it’s wonderful, it’s been a buggy troublesome experience.  I just had another frustrating 2 days where one of their frequent downloads screwed everything up.
  I tried the Bryston BDA2 as a demo and sonically thought it was a tie with Bluesound.  Does it work well, though?  Have you had difficulties at all?  I’ve been lusting after the bdp3 but it’s really pricey...

Some of you guys recommending Node 2 (used) for his $11,500 active speakers must be smoking something. Streamers do matter. A lot, especially when the rest of the system is top notch. Putting the Node2 to his Kii is like buying a $350 turntable to feed a $11,500 phono stage.

@thyname  Your phono pre / turntable analogy is pretty much what I have done with my Bluesound Node 2.  It's going into a $3500 DAC and coming out some $6500 speakers.  I think it sounds wonderful.  Things don't always have to cost thousands of dollars to work or sound great.
