I've just purchased my first 7.1 receiver, after a couple of weeks researching info about the features of several models (to meet wich meet my requirements), and after hearing Yamaha, Marantz and Denon (at 3 different stores), I decided without doubt for the Denon, the sound was better than in the others (of course that in different places, with different speakers, wich makes difficult to be absolutely sure about this topic), the features was closest to my needs, and, in my country Marantz is overpriced.
I was unsure about the Denon 2308 vs. Denon 1910, the first is older, but includs a Phono input (important for me), the second have the latest technologys like DTS HD, Dolby True HD, and Dolby Pro Logic IIz, and includes also four HDMI inputs instead of two.
My final decision was for the 2308, I bough it yesterday!
Of course, my advise is that you should try the Receivers by yourserf, and look for comprehensive info about wich features fullfill your expectations, if the one that have all the features you wants, also sounds good enough, this is for you!
