Yamaha does the whole 'audio input over the top of HDMI' too, has done for quite a long time. The whole issue with Onkyo / Pioneer Corp + Integra is that they may not be around in a few years time. They are laying of 50% of their management and 30% of all staff globally. They haven't turned a profit in half a decade and are indicating that they're dropping consumer / home audio in favour of OEM car and 'branding opportunities'. Somewhat akin to Monster's approach.
This industry is not getting cheaper and cheaper, we're simply convincing ourselves that we have to push the cheapest option to customers. #makesonosgreatagain
