Manni,From what I see here, I can attach all my 4Ks to this unit and bypass the Krell 4k unit. I can have a video wire going to the projector and an audio out wire going into the Krell 707. Is that correct?
One thing we really need to know is how long of a cable run is it to your projector from the Krell? Then we might be able to recommend just a cable that would work without an extender.
Frankly, I'm not sure what that switcher from Krell is really doing.
Barry, before trying a new switcher (like the HDFury), I'd try a new cable. Here are two options:The expensive one from Monoprice that promises 8K compatibility: https://www.monoprice.com/product?p_id=38625The value option for 4K HDR: https://www.monoprice.com/product?p_id=15427I've tested the value option at a shorter length and it worked. Frankly, I'm not sure what that switcher from Krell is really doing. How much did it cost?
$1,000
