Kal Rubinson has posted a review of the Marantz AV7005 surround sound processor ($1499) in his Music in the Round column at Stereophile. His conclusions:
I'm left with a great appreciation of the Marantz AV7005. It did everything I needed of it with great distinction, and it sounded clean and balanced in ways I hadn't heard from a pre-pro or A/V receiver costing less than $2000. All that separated it from high-end pre-pros was a slight forwardness in the sound that was most noticeable with two-channel sources, whether analog or digital—and which some listeners may actually enjoy. It's hard to fault the Marantz AV7005 for sound, appearance, or ergonomics.
