Found an interesting snippet re: MQA (I was contemplating the future of my little music collection and physical media in general – Blu-ray Audio seems to be DOA)

"Two main kinds of filter: Linear Phase and Minimum Phase (a third kind could be everything else in between). Linear maintains the phase relationship between ALL frequencies – this best preserves the timbre of instruments. Minimum Phase screws up the phase relationship and changes the timbre but it eliminates pre-ringing. Since music is all about the relationship between various frequencies then Linear Phase filtering will sound the most natural and if well designed the pre-ringing will not be audible. Minimum phase makes no sense unless you look at waveforms and dislike aesthetically the pre-ringing.
That Bob Stuart is pushing minimum phase basically discredits him and MQA as a gimmick. He is pushing transient response (an engineering concept) over musical timbre (what we actually hear or how our ears work)."
If companies like Sony and Pioneer (I'm talking about the mainstream) want hi-res to be taken seriously, they need to make it available in car audio and elsewhere, and digital streaming services need to update their libraries. The conundrum is that digital platforms evolve so quickly that the electronics are becoming obsolete faster than ever while sales of "mainstream" hi-fi products are shrinking.
I don't subscribe to digital streaming services (or digital file vendors) because I don't want to deal with a limited library of titles. If I buy a disc, I can listen to it anywhere, without an internet connection, and I don't have to keep paying or have it arbitrarily revoked from my library. I can rip the disc to a variety of file formats, lossless, lossy, etc. and play it on any device I want, without restriction.
I had to revisit this decision when I bought a limited-edition CD yesterday – the album is available for $10 on iTunes, but I decided to have the disc shipped for significantly more money. Am I becoming a cranky old man? Yes – but I'll still have the CD, which sounds better than anything Spotify can offer in 2019.
This is what Sony has for high-res car audio (not great – I hope they are doing a better job with OEM systems – would that be Ford?):

Here's Pioneer's list of high res products (starting at $300 for the portable player):
