i again went to Japonica in sarat bose road (kolkata), then there shop owner said denon is better than Yamaha from the side of quality and technology but its complex than Yamaha and also they don't have any latest model so they recommend Denon AVR1909 & AVR1908.
they price Denon AVR1908 = Rs.28000 (5.1)
Denon AVR1909 = Rs.42000 (7.1)
In my opinion why should i buy AVR1909 in 42000.
in this money Cambridge Audio 340R 5.1 is also come in 36000.
but its AVR1909 its 7.1 & with true HD.
Buddy
just go by this quotation, in choosing the amplifier...
Prefer Yamaha = For movies only...(atleast 70% movies)
Prefer Cambridge = For Music only...(atleast 70% music)
Prefer Denon = For Balanced System...(50%movies-50%music)
now, when you are talking about the comparison between Cambridge-340R and Denon-1909, so buddy Cambridge-340R is thee strating series of Cambridge, not exactly good, is just a budget system...
where Denon-1909, is nothing but the revised model of Denon-2308...
so if u compare in that way than in any case Denon-1909 takes a lead...
Now coming to Yamaha, if you look at the models like 665 or 765 they are priced @ 45-60K...
So when u r comparing plz look into the technicalities, and the performance..
all these three amplifiers has there own pros and cons...
