Summary: Airplay is a gem, but ALAC encoded files delivered via PMS (Playstation Media Sever) do not play. Needed to configure PMS to transcode to ALAC files. I contacted Marantz and they said they don't support any specific DLNA servers and they don't know what the Japanese engineers use to test with. I did find another servers for purchase that can interface with this.
Summary: The first one ordered was bad out of box, no power. The Amazon return/refund process was a hassle but in the end Amazon returned all my out of pocket expenses. Must add the Amazon rep I had was world class and her follow up a WOW experience. The second NR1604 receiver orderded is good. I like the smaller profile, current features and does not run real hot during normal use.
Love the form factor - just wish that I liked Audyssey better

Summary: I had the privilege to also audition the Marantz NR1504 , and I wrote a pretty long review for it. The two models share the same chassis (which is an outstanding form factor) and a lot of the same features, and my impressions of several things are the same, so I'll try to be more concise and focus on the differences in this review (but I encourage you to check out the longer review if you're interested).
Summary: In my mind the whole draw of this line of receiver is the size of the unit. It is just a little thicker than your average game console. The front corners are rounded back and they added round silver feet to the bottom of the unit that are slightly smaller than a beer can in circumference. It sort of reminds me of a VCR. If you are space limited this is what you are looking for. The two knobs on the front are for input selection and volume.
Summary: I'm not really an audiophile. I bought this for the large number of HDMI ports, smaller vertical size and good reviews. It was easy to set up and the onscreen configuration was straight forward. The only negative to date was that an update from Marantz via the Web wiped out my ID/Password on SirusXM .. but that happens with my Sony TV updates. Frustrating, but sadly expected these days. I would definitely recommend this product.
Annoying Drawbacks But Still An Exceptional A/V Receiver. Marantz NR1604: A Critical Review.

Summary: What a beautiful system. Absolutely Elegant in form and performance, however, for some unknown reason lack standard features that even budget brands have. *** The 1604 vs. the 1504 *** The NR1604 is identical to the NR1504 in performance with the notable exception that it has: + 7.1 Channels + 100-Watts per channel + 4K Resolution (or 2x HD) picture upgrade. Like the "1504" you have: multiple analog ports.
Solid choice for smaller systems or high efficiency speakers

Summary: Marantz has long been known to produce excellent quality audio gear at reasonable prices. Same for Denon. The two merged in 2002 and their product offerings often share technologies--probably a good thing. This receiver is relatively low power at 50W into 8Ohms. That is plenty of power to drive higher efficiency speakers in a moderately sized rooms. The NR 1604 uses discrete output circuitry, Analog Devices DSP, while maintaining a "slim-line" body.
Sony vs Yamaha vs marantz... Close but the nod goes to sony

Summary: Tonight I am presented with the ultmiate first world problem -- trying to rank 3 state-of-the-art AV Receivers. I already reviewed and compared the Sony to the Yamaha and it really wasn't close either in terms of sound or useability -- Sony was far better -- but then again, the Yamaha I reviewed was a step down in price than the Sony. I had a Marantz Slim Line that was close to 5 years old, I think?
Summary: Works as advertised. Great sound quality. But now the drawback: This applies not only to the Marantz 1604 but most electronic devices. Therefore still 4 stars for Marantz. From the male engineer perspective, this equipment is relative easy to set up and does a wonderfull job. From the (mostly) Female point of view, this equipment (and most equipment) is a desaster. I made a test to ask my wife to set up and install the equipment.
Summary: Marantz has a winner with this unit. I have it running in 5.1 mode and the spare outputs feed speakers in another room. I often will listen to internet radio on the secondary speakers while the kids are watching a movie. Surround quality is quite nice. The automated setup did not work too well with my room. I manually tweaked the speaker distances and volumes to get the right sound.
