Beginning with last year's models, Denon and Marantz are clones of each other for the most part ... 7005 <==> 3311CI with some subtle differences between models, although as noted, the Marantz model generally costs more. Although you won't be able demo Audyssey there, Best Buy/Magnolia stores offer both Denon and Marantz so you can demo both to determine if you prefer one over the other. So when comparing models, compare whether they have the same version of Audyssey at least. Really depends more on your requirements/budget and which model meets those requirements. If your budget can afford a 7005, you can likely get the 4311CI with the more advanced version of Audyssey MultEQ XT32 for roughly the same price. Also there are great deals to be had on last year's models from both mfr's.
