Actually this is why most of the hifi heads bought iPhones, 6s had the best DAC that you can buy for a reasonable price (less than 1000 USD). I have converted all my collection to ALAC just to be on the Apple platform and be able to listen to lossless on my phone. I also use a decent entry level hifi headphone (Focal Spark - wired) this is where my hearing still be able to identify differences. The entire setup was not too expensive and it had great performance. Now, if I try to have it with the recent iPhone offerings, it will be certainly more expensive and slightly shittier, and I can just convert my entire collection to mp3s because the system does not support it anyways. On the top of that, I was able to listen to my collection on my proper audio system at home before while right now I am not able to connect the phone to the amplifier anymore. So, to summarize, Apple offers my a way more expensive solution that makes me miss out on many aspects of listening lossless music. It is simply not worth it.
