I also wanted eARC for simple, one remote control of TV with best possible sound over my 2 channel stereo. Naim Uniti Nova had handshake problems, but my dealer said in his experience this had been seen in a relatively small number of units he sold. Presently the Naim is at warranty repair to hopefully fix the issue. NAD M33 has had no problems with HDMI, but I'm not pleased with its sonics for my music listening (with AudioVector R3 Arrete). So next I'm going to try an AVM CS 5.3. With it's tube front end, I hope the AVM will be my solution to both HDMI eARC connectivity and engaging music listening.
TV audio into DAC via eARC or better
My HiFi system is also in my main living room which has my largest TV for movies. Currently running optical audio out of my Sony TV into my Schiit Yggy. It's ok but something is missing for sure. Xfinity 4K box is HDMI only. Apple TV is HDMI only. I would think the highest possibly resolution would involve eARC.
I noticed the Lumin P1 has an eARC HDMI port. Looks like it can also switch video sources but my preference is to keep video quality going straight to the TV.
I know my compressed version of Batman on Netflix from my Xfinity box isn't going to be great but I need something better!
Thoughts? Thank you!
