Just be sure to forward the HDMI issues to Meridian with the HDMI device chain and cabling clearly stated.

Also about "Hi-Speed" HDMI cables, not all manufacturers test every HDMI cable shipped, it's economics involved unfortunately.

Changing an integral part of the HDMI chain as the HDMI switch and keeping your old cables does not mean that the old cables will work automatically, you can hope they will but there is no guarantee if they are on the threshold.

@Rolski, the issue with changing channels on a TV-box losing audiolock after the UHD722 compared to the HD621 should really be forwarded officially to Meridian, I think you are on to something that could be done to smooth how things work the sync and audiolock. Maybe the HD621 kept it sinked or padded things differently when the a TV-box abruptly cut the LPCM stream when changing channels.
