What Marantz Cinema 50 owners say

“I tried Dirac on my Marantz Cinema 50 for the first time this weekend. The improvement over Audyssey Multi EQ was dramatic. Detail and clarity have improved to the extent that I would expect from whole new speakers.”

“The Cinema 50 is definitely not plastic. I have it and also it says on their website spec sheet that it is metal. It is solid and gorgeous especially in silver.”

“It's been the case since day one, only works if eARC is disabled but you lose Atmos -.- really unprofessional and very unhappy so far.”

“I have the NR6100. It’s a great receiver at the price point! I loved it for a while but found myself needing more power with a speaker upgrade. I’m sure you know but without pre-outs that’s not possible”

“Bought a new one (TX-NR6100 practically identical some people refer to yours as the “Costco” variant)and had nothing but issues (HDMI signal appearing the same as your 2nd picture and complete loss of signal) Returned for a replacement and the 2nd one did the exact same.”
