My memory of the Marantz amplifier is it’s bit soft sounding in the bass, treble. While still being extremely refined. It’s rich in the midrange, while also being bit thin at times. Overall quite warm sounding. It’s difficult to explain. You need to hear your self. I’d give the Denon 1600NE chance also.
Marantz isn’t so powerful per say. On paper they are. Since they are soft sounding it can rob music drive, punch. This is what I mean with powerful sound. You can crack the volume, but it never really go nowhere.
Still if you get the perfect speakers you can’t go wrong with any Marantz amplifier. Design wise they are beautiful. And many of them are build like tanks. I might give Marantz another chance in the future.
I’d give the it chance if you like the Marantz sound. Many do. They still, and always we’ll be one of the most respected brands on the market.
