Is it an older amplifier with basic aptX only, not featuring “HD” with at least 24 bit of depth capability at 48 kHz?
When it comes to AAC, with the iPlay 60 mini Pro in use, I can’t tell about the actual AAC depth and frequency maintained while transmitting, unfortunately since it’s not indicated in my headphones app.
LDAC while at 990 kbit and 24 bit still is the only full range – low distortion codec available. Yes, it’s proprietary, for sure. Here’s the comparison I’m relying on:
