I recently tried playing MCH FLAC directly on my Denon X7200WA and it failed (both from USB and Server).
I was trying to establish whether the Denon would play quad from FLAC. Fail. It will if I use a media player.
I tried to play files from an HD on my last years Marantz model and it wouldn’t accept NTFS, only FAT. My new Denon will accept NTFS via the HEOS configuration. However, it won’t play multi-channel files like my OPPO but will play DTS-CD multi-channel files.
