Is there really a Bluetooth lossless option now? As far as I'm aware it is not possible to use Bluetooth for lossless audio at CD quality, i.e., 44.1KHz/16bit.
The Apt-X Lossless and Apt-X HD BT standards are very good, but unless there has been some recent developments I'm not aware of they still cannot handle full CD quality audio. The best lossless compression algorithms reduce the 1.4mbps CD stream down to about 300-900kbps range, and I think Apx-X HD throughput is still at around 576kbps max. I read that they can run lossless much of the time, and then switch to lossy only when the dynamics of the music require it.
If you know of a new BT lossless standard please send a link as I'd like to learn more.
