I have a Yamaha BD-A1040, and I can tell you, trying to stream any video from it is a painful and terrible experience. And the internal DAC? Nope, all my CD play goes digital cable out to my PS Audio DAC>2 channel pre. For me, it’s basically a transport, and the rare DVD or BlueRay disc use, but again, that is almost never used anymore. Not with the options available by streaming devices and services.
I have a Yamaha AV receiver which drives all my HT 5.1 sound, including my Yamaha DVD/BlueRay via an HDMI to the AV receiver. All my music is 2 channel and separate (amp, pre, and sources), the pre-amp has a pass-through for the front main speakers when in HT mode for watching TV and movies.
Pretty simple really. My Roku is connected to the TV via one of its HDMI ports, then sound from the TV to the AV receiver via another HDMI (ARC) port (I don’t need an optical cable for sound from the TV). So, all video streaming is done by my Roku (or Samsung smart TV) and sound fed to my AV receiver via the ARC HDMI. My DVD/BlueRay connects to the AV receiver via HDMI for 5.1 playback. And again, for music use, connects to my DAC via digital cable. Again, many video and music/radio streaming options with the Roku, including Tidal, although I don’t use Tidal through the Roku, but can.
Bottom line, I doubt anyone will be too happy streaming through a DVD/BlueRay player available today. Some say Oppo’s are better in that respect, but not made anymore, so non-upgradable for various existing and new services. That is a technology that has been surpassed by a Roku, Fire Stick, or similar, is a much better experience, and has updatable OS software via internet connection. These players/streamers like my Yamaha haven’t had an update in months if not years, and cannot come close to the performance of the alternatives available.
I don’t have cable, I switched to streaming my TV (or by antenna for air reception). It’s the future, and a future I doubt any of the DVD/BlueRay players can or will try to compete with going forward.
