I'm also thinking same question. I already bought Marantz PM7000N, but I have return policy in place which is not surpassed. Local dealer just dropped Hegel H90 price from 1500 to 1200 euros so the difference between the prices of the amplifiers is non existential.
Which one would you choose? I have KEF R3's.
I like the features and GUI in Marantz more, but in A/B testing I was leaning towards Hegel. BUT, was the tiny difference I could hear (or did I just imagined, that's a good question also..) really worth to not take features like wi-fi and bluetooth. I don't know.
