Hi, I'm buying a Denon receiver that I will use for two months for a film project, then pass on to my girlfriend who will use it for a basic two-channel music and movie system and eventually add 5.1 speakers. I need very clean, flat, accurate sound. The Denon AVR-2105 seem like a good choice. But I'm wondering if the AVR-1905 would work just as well? What about the AVR-1705? On the other end, is there any really compelling reason to go for the AVR-2805? It is a bit out of my price range and would rather put the money towards better speakers anyway. Finally, I am pretty sure I want a Denon, but am open to compelling reasons to consider something else. One dealer recommended Yamaha RX-V657 for example, but another dealer said that the Denon's have true amplifier circuitry, whereas the Yamaha and other lower-end brands have their amps in IC's. Any thoughts or suggestions greatly appreciated. Need to make a decision ASAP. FWIW, the receiver will get matched up with a Denon DVD-1710, and a pair of either Paradigm Titan, Mini Monitors or Monitor 3, or B&W DM 303, DM 601 S3 or 602 S3 (open to speaker suggestions too !) Many thanks.
