Headphoneus Supremus
I was curious and did a comparison just now with my XM2, playing Spotify on iPad (AAC) and Galaxy S9 (LDAC). I was expecting to strain to hear a difference, but to my surprise LDAC was noticeably better. I listen primarily to classical music and played some complex orchestral passages of Shostakovich. With LDAC, I could pick out more detail in the instrumentation, the strings sounded smoother, and the whack of the tympani sounded cleaner and more convincing. Honestly I wasn't expecting to hear such a clear difference.Spotify maxes out at 320Kbps bitrate using Ogg Vorbis format.
Bluetooth AAC maxes out at 250Kbps (?) bitrate.
I was* considering moving to Android in order to try LDAC, but it seems sticking to Spotify won't make a difference at all when using the M3s because of its max bitrate. Am I correct?
I think the logical conclusion is that the Spotify Vorbis encoding is higher quality than what most people give it credit for, and transcoding to 250 AAC degrades the quality. I'm just one data point, and I hope that others who have both iOS and Android devices would also do a comparison.
