Amazon music is pretty much only available on Bluesound and PCs.
The bridge has no capability of local file play, your only hope of music when the network goes down. You will be giving up many functions and streaming services. This is not an upgrade in my view.
I ordered my Directstream Sr. specifically without a bridge.
I moved from Bluesound to a Magna Mano Ultra with i2s output and never looked back. Consequently a homemade Raspberry Pi with PiCorePlayer can include services unavailable on Bluesound.
I had Amazon and Qobuz and kept the latter as it sounds better to me.
A miniDSP SHD Studio, a Pro-Ject Stream Box S2 Ultra and an Allo USBridge Sig all play Qobuz with excellent results, AND are upgrades to a Node.
