Audiophilia is a niche within a niche. I’d be surprised if it were worth more than a small fraction of Apple’s iWatch replacement band business. RoonLabs knows that, and seem to be content being the big fish in that pond.
Yes and no - show me the way to the next Ravenna-powered playback device. Or to the sane uPnP setup. Now, if we look at the current state of the CE field (and that includes in-vehicle), what you’re describing hasn’t happened, and much the contrary, seems to be going in the exact opposite direction: you have devices that support all the damn protocols (even if that means running on questionably sane software platforms, yes, I’m looking at you, Audio Pro). As long as it’s relatively cheap to do so, I’d love to hear why a sane manufacturer wouldn’t do just that if they aren’t subjected to strong-arm tactics.
