These two models are quite alike, but there are still some differences. I had a chance to compare Marantz NR1608 vs Marantz NR1609 and I would like to make a short comparison that will help you choose the right receiver.
These models have powerful codecs that can play almost all audio and video files. However, NR1609 have better codecs that can assure higher compatibility. Both models support the 4K video standard at 60 Hz assuring the absence of motion blur. HDR and HLG technologies make colors vivid and pure. Both models also support the Alexa voice control technology.
Both models support Wi-Fi and Bluetooth connection, which is also necessary for the HEOS technology and AirPlay. Marantz also has an AVR remote application that is used instead of a remote controller. This application is available for iOS and Android. If we compare the ports, we will see the difference - NR1069 has a phono input and two audio-only ports, while NR1068 has only 1 audio-only port and no phono input at all. The audio calibration is performed by the Audyssey technology (the microphone is included). The Audyssey includes several subsystems, like MuliEQ, Dynamic EQ, etc. Everything can be tweaked easily via an application with the user-friendly UI.
These two models look almost the same. The first thing you notice is that how slim they are. Both have a simple LCD display, two knobs on both sides, an on/off button, buttons to select the source and input ports (USB, HDMI, Phones and setup mic). The buttons are quite wide so you will not press something accidentally. The remote controller is ergonomic. It has everything you need to control the receiver. Comparing Marantz NR1608 vs NR1609 in terms of size, we will see another difference – (NR1069 is 14.5) 14.8x17.3x4.1 inches. Their weight is 18.3 pounds.
