Marantz has hit a home run with the Slim Line home theater systems and I highly recommend this product.

Summary: I have been playing with stereo equipment since the early 70's but it has been about 20 years since I purchased a Kenwood system that still works to this day but would not fit into the new home theater cabinet my wife and I recently purchased so I went in search of a low profile system and...
Summary: I purchased this receiver as the heart of my surround sound system. It effectively powers all of my speakers and was EASY to set up, The auto setup takes you through calibration of the speakers and hook ups for your other components (Xbox, PS3, etc.
Summary: Bought this model on closeout, the new 1604 adds 4k upscaling and another HDMI, which weren't worth the price increase to me. The amp sounds great, dont let the "50W" power output fool you, it is plenty for my home theater system.
Summary: This receiver is truly amazing. It was incredibly easy to hook up. Literally just a few moments after opening the box, I had it connected to my system. I have loved the ongoing utility and performance of this unit. It has 6 HDMI ports, SIX!

Summary: Purchased the NR1603 three years ago to replace an eight year old Onkyo receiver that didn't support HDMI. Set up was plug and play, very easy, took about 90 minutes. It is being used to drive a small Energy 5.1 set of surround speakers with sub-woofer. Perfect for our small TV room.
Summary: I use my NR 1603 with Polk tower speakers, rear speakers, center speaker, and subwoofer. I've also got it connected to a router via Cat-5 Ethernet. HDMI inputs include Samsung Smart Blu-ray player, cable box, and a desktop PC. Output via HDMI is to a Samsung Smart TV.
For single room installations this is hard to beat

Summary: Pros: Love the low profile - after years of giant A/V boxes this is a refreshing change that looks great and more importantly frees up some much needed room in my cabinet. It's also not quite as deep as my old Onkyo. It sounds great.
Summary: I've owned the for some time now and I'd like to compare this Marantz receiver to my Sony. (Edit: 5/29/13 - This Marantz receiver has recently dropped in price. It used to be $250 more than the Sony STRDN1030.
