I have a McIntosh MX123 and am able to configure the Rose as a component, so I don’t see why you wouldn’t be able to. I have my analog outs going to the MX123 and my HDMI out connection going directly to the TV to ensure I get the highest resolution and audio quality (though I started having an issue with the video out with a recent update, so I’m hunting that down now. I didn’t think you would have this issue if you were using the HDMI out for video and audio playback through the Anthem).
Can the 105 be integrated into the AVM 90 from Anthem as a component?
