It looks like no according to their specifications.
When reading the manual for the AV7005, it looks like it will stream FLAC over the network. It seems strange the UD5005 does not. Both say they are DLNA 1.5 devices.
I know there is a lot of love here for the Oppo-93, but does anyone own the Marantz? Anyone have any thoughts on this model vs the Oppo?
I was considering an AV7005/MM7055 setup at some point in the near future.
