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.”
