I'd agree. We may this Apple Music and iTunes/Music app support purchasing and direct download of HD music (over 992kbps bit rates in Apple Lossless or FLAC when the Apple over-hear 'Pro' headphones debut later this year. Also considering the HomePod does support HD music.
Currently, lossless CD quality music at 16/44.1 is supported through Airplay. Wouldn't really call it HD music unless it's beyond CD or DVD quality (16/48 KHz)
While Sony has LDAC (992Kbps bit rate over Bluetooth - supported since Bluetooth 2.0+EDR) as a better alternative to AptX-HD (55x kbps bit rate), we need to know which iPhone hardware model supports streaming at larger bit rates and is it 24/44.1 bits. Sure my ears (47) may not hear anything at 12/15hz (or is it kilohertz I'm not sure ... think Teenbuzz test LMAO) Some music with great speakers ... you can just feel extremely low bass (bass bins).
Unfortunately Bluetooth doesn't even come close to what WiFi can deliver straight from iOS 13. Current 3rd party iOS app can deliver 1 bit 22.5 MHz streaming or DSD512 (or 45,158.4 kbps audio stream, much bigger than 992 kbps offered by LDAC)
This is why I'm praying for Apple to do three things:
1. iTunes & Apple Music (download/streaming respectively) for music!
2. iPhone's (since Apple iPhone 7 onward) to support up to 44.1Hz and over 1500kbps (please)
3. HomePod line of speakers - a Soundbar, a dedicated Bass woofer (8-12" cone size), and smaller dedicated tweeters!
(ability to pair these into a 5.1 channel setup)
This could allow Apple to get into the car audio market too as a nice benefit ... after all they do make 'consumer electronics' not just computers.
1.) Currently only Apple and Spotify are the only streaming services that don't offer lossless CD quality, let alone DSD streaming which none of the streaming services on the market actually offer. From Apple's POV, music streaming isn't as profitable as iPhone itself so I don't see them switching to lossless in any foreseeable future.
2.) Bluetooth needs to get to around 7000 kbps bandwidth (overhead is accounted) with enough range to support true hi-res 24/192 lossless stream. 1500 kbps might support some 24/44.1 tracks, but some of those tracks can exceed that based on how much information the song contains, and that 24/44.1 uncompressed is actually 2117 kbps.
3.) Competition here is fierce, but I do hope Apple makes a concept of that for a modern living room look
As for car audio, Apple has to prove that they can compete against the likes of Bowers and Wilkins, Bose, JBL Premium, KEF and Meridian Audio for car audio. Tough market to get into to be honest.
