I know this is a weird comparison, but long story short, I am deciding between these two receivers both of which are in my possession. The return period on the Marantz is in 6 days so I need to decide soon. Marantz is setup with the polk towers. Yamaha is still new in box.
1) The Marantz NR1607 has everything I need for now. It has the latest codecs and I dont see it being obsolete anytime soon. I bought it on amazon for $450. I figured I would throw down another $200 for used amps if I needed more power
2) During my speaker purchase (2 weeks after I already bought the NR1607), I acquired a Yamaha RX-A2060 for an extra $700. This thing looks like a beast. I was planning to sell it for $1000 to make up some of the money I spent on the speakers. Recently I have been reconsidering and might keep the A2060 for myself and return the NR1607. The Marantz had some freezing issues which ruined the moment, but a full reset seemed to have resolved it.
Details: Average sized apartment. 90% music use.
Main: Polk Audio LSiM 705 towers | Center Polk Audio LsiM 706 | Surrounds: Polk Audio LSiM 702fx
Zone 2 - bedroom: Polk Audio LsiM 702 bookshelf
Unused speakers: Energy Take 5.1 version 1 (not the classic system). If I ever decided to do Atmos/DTX:X height with the A2060, I would use these speakers.
