How did the testing/ comparisons go?
Went about as well as one could possibly expect. From a sound quality perspective the Wiim is every bit as good as the bluesound. I prefer being able to use Amazon app to stream natively over blueOS although Blueos is a great UI software for what it is. The only issues I have with Wiim is the amazon app can have latency issues with it where I hit next/pause/play and there is a lag. Also after a short period of time when I stop streaming then open my phone and start again it will lose pairing with wiim pro device. Then when I try to reconnect it will spin and say error. So just a few minor quibbles.
I'm consiering buying 2 more wiim pros with how cheap they are and how well they perform. Next up I'm going to test Bluesound node and Wiim pro through a DDC and then into my Dac via I2S to see if there are any SQ improvement comparisons.
