The take away from the discussion is that we can get hires lossless audio easiest with an India credit card, Apple Music, iPhone or iPad, a DAC like btr5, and any suitable headphone. Bluetooth headphones introduces lossy.
However, human hearing can't access the extra information that 24bit depth provides with the lossless format. 16bits, CD quality, is the maximum. We loose the inaudible 8bits. So any set up providing 16bit/44.1kHz at 1441kbps (wired, because hard for Bluetooth, although claimed for by LDAC at 960kbps) or almost the same, 16bit/44.1khz compressed to give lossy files with 320kbps bitrates, like mp3 or ogg vorbis (easily handled with aptx HD transfer rates) should work. So Spotify Premium subscription with Spotify Connect devices can give almost CD quality even if there is a wireless connection involved. Just avoid Android. Maybe by Sept 8, with Android 14, we may get exclusive use of the mixer, which means no compulsory use of the 48kHz resampling.
