Hi All,
I'm a Marantz NA-7004 owner.. For those who wanted to know.. This unit play gapless via UPnP and USB using it's own remote only. It doesnt play gapless using D&M apps..
I have tested using jriver DLNA, Mezzmo and foobar DLNA... It's weird as other manufacturer can do gapless using their apps remote. in Marantz case, you cannot use the units remote and apps remote at the same time.
