Which site is Best for Downloading/Uploading Hi Rez

I was a fan of Bluesound but have soured on it recently due to a lot of technical issues.  They do many updates and many of them are destructive, erasing my playlists and causing my Vault and Node2 to “dissapear”.  My Pulse Mini completely died  after two years of use.  It’s off warranty and the dealer went bust so I am SOL per Bluesound. As to why my other players dissapear occasionally from the OS, I find this totally frustrating since I use Ethernet connections and not WiFi.  The Bluesound app is nothing special, either.  You need playlists to make it work, and as I said earlier, twice Bluesound OS updates have erased my playlists.
  I had gotten into Bluesound because I had wanted to get away from using a Computer, but have found it to have many of the same issues.  When it’s working, it does sound good, but so what—it’s a digital transport it should sound like any other digital transport through my DAC.  It’s internal DAC is nothing special, but at it’s price point that isn’t unreasonable and I only intended to use it as a transport anyway.
  I’ve realized that having my CDs stored in a proprietary system like Bluesound is problematic because if you want to switch to a different player, the stored discs aren’t necessarily portable.  I have gone back to spinning CDs—nothing beats the fun of hitting play and getting music without having to make that call to Tech support—but I am installing a NAS Drive today and hoping to at least archive my collection while figure out the optimal player to use 

@mahler123.
 I feel for you but not quite sure what is happening in your case. I have had many updates to the vault2 over the air and to the Bluos app and have never had one single issue.
Also not sure what you mean by having to have playlists to make it work?
I think I have just one playlist i assembled over time but it has ,nothing to do with making it work.
I just favourite albums from searching and play them or go with new material totally, no playlists involved.

If you want to move your CD collection you just take that back up 2tb usb hard drive you should have made already from day one and regular updated and there is your CD collection.

Ok,

   So It seems that there are quite a few streaming sites available(besides the more well known ones such as Spotify,Tidal,and Deezer).But it seems that the ability to retain certain files to be uploaded/downloaded/stored,on your computer/tablet/iphone/droid/desktop is still non permissable to the average consumer! From what Im seeing,its a copyright infringement.But I am looking for a viable alternative to just Youtube,Googleplay,or iTunes.I get the feeling that these are all compressed..But if I can find the ideal site that I can stream,and rhan keep certain files(move them to an SD card)for personal use,and be a bit closer to cd quality,(or 16 bit/44 khz),I would be more than happy.

The whole concept of streaming music to the masses is just that, stream it , not buy/own it.
There are some options for downloading hires tracks for sure but none of the ones I have seen are what you would term cost effective but that is up to the individual of course.

Fair enough!

               I dont mind all and out "Streaming" per say.Its just that I want to go portable with a headphone amp/dac(or digital audio players),
And I dont know if these devices support direct streaming! Hope so..I have no qualms of plain ol streaming through my cambridge out to my laptop than router,than through my audio gear.But is it "Plug and Play" with other digital devices..?
