So can we agree that; If you pay for Apple Music, and your hearing is good enough, And you buy a decent set of HiFi headphones as well as a separate DAC/amplifier (like wot I said). It is possible that you may be able to gain some benefit from Apple’s High Definition Lossless Audio stream ?
Yes, but with the Apple dongle, I found it not better than Dolby Atmos. I don't get Spatial Audio. Lossless sounded ok at the 2nd tier. I just think Dolby Atmos is better. And, with an Apple listening device, add Spatial Audio, and it's even better, with no wires.
