I had a Marantz once. Probably 10 years ago. The most horrific customer experience I've had with any electronic device. Refuse to ever buy Marantz again because of that experience. Didn't even bother to look and see what they have.
Go with Denon, then.
Why? I already have the Anthem. Noisy fan and all..... But hopefully, the cooling fan I have ordered will resolve that issue.
