The drive noise is in normal operation quietly, in quiet passages perceptible does not really bother me, but louder under the annoying menus a BluRay / DVD. (It's time that it has turned out in these devices, the technology could be long on the mechanics do without, even though then the last cult by the wayside => eg USB stick, SD card ...)
The remote control is better and clearer than the AV7005 at almost the same division, but does not have key lighting. Due to the different color of the keys I think they intuitively often upside down. Since I am increasingly farsighted, my label is too small. The buttons for the (AV) or Setup Menu (BD) and return are arranged exactly the opposite on both remotes, incorrect operation guarantees which of course is only important if you own more Marantz devices.
SACD's sound excellent, the player plays without cheap showmanship at a high level. This is hardly surprising, since the output is done via HDMI and thus lossy D / A conversion externally, in my case, to be done in the preamplifier.
Since then I have only seen 4 Ice Age in 3D, which was also blameless in quiet scenes the picture is a little tiring with a clear signal depth, the colors have subtle contrasts, here I am also satisfied. For high-motion scenes sometimes bothers me not quite the quiet end of the scene, but I have seen here in home cinema has never really what Convincing from a disc. The cinema can be better.
Annoyed me a sticker on the top of which adhesive has changed the surface. The impression can neither alcohol nor with WD-40 and also not remove with glass cleaner. Ever bother me when unpacking the cheap-looking stickers to provide information what the unit can do. It's like advertising showcase in Hong Kong, but does not fit into a valued instrument.
Since now nothing works without a network, integrated WLAN would be useful. So I had to buy a wireless Ethernet adapter, but only in accordance with the I plug in to update where I see the need.
Stream pictures or music is too cumbersome on the UD5007, which can eg Apple TV or the OPPO BDP 103 much more comfortable with significantly less format limitations. My music is about 98% in lossless format (* .m4a / MPEG4) on the hard drive. The Marantz UD 5007 can only handle MP3, a DLNA server vorrausgesetzt on the hard disk.
Conclusion: If you just want to play discs, get a good unit, its display can be turned off.
