If you want Dirac, look for a used Nad 758v for just a few hundred more= no more problem!Hi everyone. I recently bought a Minidsp nanoAVR DL but I only found out when I tried to set it up that the unit does not support 4k or 4k pass through. My problem is that my sources are all 4k and I don't want to just set all my sources to 1080p when I paid extra for all the 4k sources. I told Minidsp about this and they said they don't have any products that support 4k and Dirac live. They suggested using a matrix switcher to split the video signal to have the Minidsp receive a 1080p signal but have my projector receive the original 4k signal from my source. I'm not familiar with matrix switchers so I don't know if this is possible. Has anyone here tried anything like this? Can you recommend any products that would be able to do it?
