It is now January 2020. The firmware update doesn't help the HDR issues. Has Klipsch abandoned the future-proof Reference Wireless system? Where are the firmware/hardware replacements to enable the 4K HDR functionality that enthusiasts expect?
I do see the new AXIIM LINK HD WIRELESS TRANSMITTER, but this isn't a replacement for an HDMI wireless receiver. USB audio isn't going to enable home theater wireless audio.
