Hi this is my first post here, I work for a home theater store and I need to be able to play my collection of flac files using the receivers we have in the demo room. I only have access to the front panel of the receivers, the ones we have in our studio are pioneer elite, denon, yamaha, and marantz. Would I be able to use my iphone xs max + lightning to usb camera adapter + audioquest dragonfly red + 3.5 mm into the 3.5 mm on the front of the receiver and then switch the input to that and play the flac files from my vox app and have the music sound hi-res?
