@Cane:
I'm sorry, but I don't think SONY would agree on that kind of license policy.
The Per Unit License is managed based on Bluetooth MAC address range.
Technically, it's possible, but SONY won't agree on that.
That means we have to buy all the copies of the license for full consecutive Bluetooth address range at a time.
We're continuous tracking the market's need.
LDAC is a good option but for high-resolution streaming above 24/48KHz, which aptX-HD provides,
requires a certain level of good enough RF environment.
Unless otherwise, it will limit the streaming bandwidth, just providing standard quality.
As long as LDAC is getting popular, we'll definitely add LDAC option in the future.
Thanks and Regards,
