Well, I can tell you that I had the same problem and probably worse because I own a BDP-1 which it significantly slower than the BDP-2. I was so frustrated when trying to stream from Tidal, when it worked the sound was fantastic but after a while it would freeze and would take forever to load the next song. All this changed for the better when I added ROON to the Bryston. Everything works great now and it is really quick. Yes, I do understand that this is another subscription on top of Tidal but it is a great option that would allow you to keep the Bryston which in my opinion is a fantastic player.
Hope this helps.
