Interesting that JRiver is not working out for you. I'm not a fan of Itunes in general, but one thing I do like is all my purchased songs populate to my iphone and ipad. Aside from that I have no use for itunes anymore.
Okay...I ripped a multi-ch SACD this morning into JRiver. Prior to that I created a playlist titled Hi Res Multi-ch...soon after I ripped it...I migrated the files to the newly created playlist.
With the Marantz source set on Media player, multi-ch (with the hdmi connection)...the files playback fine....in multi-ch....via wifi.
Now that I've hooked up the external drive the laptop is not easy to move near the system to connect via the USB...I will be moving the laptop over near the system permanently when the laptop is taken out of service for my biz. I'll try the USB connection then and see if I get multi-channel via USB.
