On the subject of 4K sources, does the talk of a 4K Blu-ray player kind of surprise you? With much of the world going towards streaming, I am seeing 4K Blu-ray is a distinctly risky endeavor for smaller manufacturers. I can picture the Yamahas, Denons, and Integras sourcing out a player from Funai or somebody that makes them cheap. Producing their own would be too expensive.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
