Guys- Going in a different direction- I spend most of my time in my car with a High end car system using spotify- Would being able to download the higher resolution from Amazon result in a better sound for the car also- thanks
Fluffers...I’m all about great sounds in my ride which includes a JL Audio 12" sub. I usually play lossless FLAC files from a connected flash drive. But let’s get serious. Road, engine and wind noise is going to negate any benefit provided by high resolution music files. High bit rate MP3 is good enough...just don’t worry about it, crank up the volume and enjoy.
Uber...do you still have your Bluesound equipment?  I’m guessing not or you would have tried it by now.
  I upgraded to the Bryston BDA3 for my main system but there is no Amazon tab as of yet.  I still have my Bluesound equipment (mainly using the Node2 into two HT systems elsewhere in the home) but I am gun shy about doing a BluOS update, and have avoided doing them for months, because doing updates had led to problems in the past).  Maybe I will just wait for Bryston to add Amazon

I've had my Bluesound Node 2 for quite awhile now.  I have done every update, (probably around 6-8 total).  Never had an issue.  None, nada.  Went perfect every time.  Not sure what problem(s) you encountered, but I sure haven't had any...
