English translated High Fidelity review of Lumin X2: https://highfidelity.pl/@main-1573&lang=en Note: X2 is discrete Sigma Delta, not R-2R

"bit-perfect" is clearly NOT true for conventional digital volume for the purpose of playing with replay gain (not talking about the original files - which is misleading), and can easily be proven. If you use Roon, it has a signal path that clearly turns from Lossless to something that means...

That's a HTTP disconnection by the radio server. If is somewhat similar to the case when you're downloading a large file over a long time, it suddenly disconnects before you can finish the download. If you can find different URLS for the radio station you use, you may try the "Custom URL"...
