@kota1 - "Why would I want to BUY multiple sources, dacs, and preamps today that will be boat anchors within five years?"
What hi-end manufacturers are you seeing divorcing themselves from 2 channel audio that this is going to be the case?
(This is a more appropriate thread to continue this topic so I moved my reply.)
The answer is Sound United, as they were just acquired by Medical Supplier Masimo, Harmon Kardon was acquired by Samsung, and the "high end " industry is being replaced by mobile headphone listeners and home theater, by far.
Atmos is backward compatible with headphones, cars, TV’s, and every variation of speaker setup you want want, from soundbars, a pair of speakers, five speakers, seven speakers, sixteen, etc. Atmos is being streamed online in video and audio, live TV broadcasts, in movie theaters and live performances. Don’t get me started on gaming and VR but you can look it up.
Do you remember what the iphone did to the blackberry? When apple adopted spatial audio it changed the music industry forever, I am not investing $$$ into what I perceive as an audio version of the blackberry.
Next question?
