I mean “yep, you can set SBC to work at way higher bitrate and perceived quality”, but I don’t actually agree with this topic title - LDAC forced to work at 909 kbps (16/44.1) still transmits about 66% of the data vs. uncompressed raw PCM (wav), and I’ve seen no evidence that SBC-XQ should be expected to sound better at 551.2 kbps or whatever is supposed to be achievable on most devices today.
You could argue SBC-XQ is practically better if you can show both are transparent and then SBC wins… on connection stability and power consumption maybe. But you can’t say SBC would “sound” better, since both are using similar non-psychoacoustic encoding principles, the one allocating higher bitrates should sound better, if there’s any difference in sound.
