I really wanted to use the Ultra Amp as an AVR so that I could have wireless surrounds but the minimum 70ms audio delay makes it IMO unusable for TV/Movies. Has anyone found a solution? I've been trying to find a device that can introduce video delay but so far I've struggled. Maybe someone is aware of a future fix from WiiM. I understand the need to the delay to sync multi room audio but for video I'd honestly be with the ability to set a very low delay for the fronts and have the surrounds slightly lag. That of course would probably mean needing the ability to have a wired center. Did WiiM introduce 5.1 just for music? That wouldn't really make sense as I don't think anyone wants or needs multi room surround.

Thanks

Zack
