BT 5 has max bandwidth of 2Mbps, which would in theory be enough for “CD quality”, i.e 44.1khz/16 bit raw uncompressed audio, as that’s around 1.4Mbps. In real life conditions it isn’t. AFAIK aptX lossless gets close by doing some compression.
But if you go full audiophile levels and start demanding lossless 192khz 24 bit audio, that’s 10Mbps and not even remotely possible over BT no matter what you’d try.
