Using BDA 3.14 as a streamer. Here are my experiences.
1. Yes, the UI is outdated, but it is functional.
2. I do have the BDA 3.14 wired directly to my router. No WiFi.
3. The 'lost connection' happens if I switch the BDA 3.14 off/on and try to use the old browser session. Now, I always start a new session from 'My Bryston' after turning the BDA 3.14 on. And, I need to give the BDA 3.14 time to boot up. No problems with 'lost connection' any more.
4. IP address will change if you have the BDA 3.14 configured for DHCP. You can assign a static IP to remedy this.
5. Even with these limitations, the BDA 3.14 is my best sounding streamer.
