do you have denon avr-790? please pm me the price if you have it.
Q. What is the difference between the three-digit models (e.g. AVR 790) and the four-digit models (e.g. AVR 1910)?
A: Essentially, NOTHING. Denon puts out two parallel receiver lineups, with four-digit and three-digit model numbers. The four-digit models are generally sold by high end stereo shops and custom installers, and the three-digit models are the "consumer" version sold in retail outlets like Circuit City and Fry's.
However, there is ZERO difference in terms of power, specs, sound quality, build quality, etc. between the two lines. Denon has been doing this for years, it is exactly analagous to the Yamaha HTR and RX-V parallel receiver lines.
There will usually be one or two minor differences to differentiate the three-digit and four-digit models. There is typically a slight cosmetic difference between the two lines, and different remotes.
In the specific case of the 1910 vs. 790, the only differences (besides the cosmetics) is:
1. the 1910 has A/B speaker switching, whereas the 790 only has "A" front speakers
2. the 1910 adds a "room to room" remote control jack for wired control from Zone 2
In all other respects, the 1910 and 790 are IDENTICAL.
