Streamers under $1500

I too support the WiiM Pro Plus as  a great, easy to use way to start streaming. I went from an Amazon device to these and really noticed a difference in sound quality. The app is easy to use and quickly links to Amazon, Tidal or Qobuz so I can access about any type of high resolution music that I want. I know they are better units out there but again, for me at least this has been a great way to get started. 

Check out Small Green Computer and their selection of Sonare streamers.  Excellent sound at reasonable prices, IMHO.

I agree with the last several posts.  The Cambridge CXN100 is excellent.  Easy set up and sounds terrific. Whether wifi or ethernet.  I use Qobuz.  

I will have to chime in again. Although I don’t have any direct experience with the Cambridge Audio streaming solution, I did recommend the CA integrated to a friend. He can bluetooth to it and use a hard wired usb from his iPAD. I sold him a pair of B&W 600 series speakers to go along with it. He was so pleased with the sound he ordered a CA CD player to go along with it.  So I think their gear is solid and right up there with the best buck bang solutions in the industry.

Frankly I dont get the Wiim recommendations. I can see it for entry level or secondary systems but that is not what the OP ask for. He already has a purdy solid streaming device and he ask to move up.

I second the Innuos Pulse Mini, this will be a significant upgrade in sound, and has well liked software. But, you will also need a DAC. Watch for good used deals.
