Had the Denon 2808 and just replaced it with the Cambridge Audio 551R which is actually cheaper in Australia than the Denon 3312 the 'natural' 2808 replacement. This is my mini review posted elsewhere:
I had to replace my Denon 2808 and sweated profusely over the replacement as my budget is very tight, sub $1,500. Preference is for great audio and musicallity rather than the biggest boom for the buck.
My system comprises:
TV:Sharp Aquus 52"
DVD: Sony BDB S380 [a cheapie, but goodie]
Mains: Krix Neuphonics 1.1
Surround: Wharfdale Diamond 9 [relatively cheap, but OK]
Centre: Wharfdale 9 CM
When it came to considering replacement receiver I looked at in order of preference:
a. Emotiva UMC-1 + XPA-5
b. Arcam 360
c. Cambridge Audio 551R
d. Denon AVR 3212
e. Onkyo TX-NR1009
Now when it came to preferred system the Emotiva made my mind salivate, but it was just too expensive. The Denon 2808 just didn't do justice to the system when I replaced KEF Codas with the Wharfdales, it sounded flat, like it just didn't have enough grunt, and when I had it benched recently the LS said it only put out 40w per channel all channels driven, which he said was typical of most Japanese spec Amps and receivers. So I scratched the Denon 3312 off the list.
But onto the replacement, I was very keen too on the Arcam but cash would not go that far. Auditioned the Cambridge hooked to the Neuphonix at a LS and was reasonably impressed with its ability to sort bass; mid range and high range in battle scenes and its musicality when played with music CD. Went to audition the Onkyo vs Cambridge but the LS couldn't demo, so I had to listen discreetly with each hooked up to Paradigm monitors plus a variety of Yamaha receivers, A2010 and some separates.
Reviews played a part with much being written about the Denon which were predictable for guys who evaluate AV on bells and whistles, Onkyo fairly similar but underwhelming, and Arcam which received rave reviews, but I could not find anything on the Cambridge Audio 551's, except one Chinese magazine where it was a recommended buy, and I don't read Chinese. The Cambridge is rated [conservatively] at 60w per channel all channels driven into 8 ohms.
Finally, budget ruled and I chose the Cambridge Audio. I was pleasantly surprised how easy it was to set up compared to the Denon 2808. The written manual is not as good as it should be, but with a little bit of guessing, all was well. The On Screen Menu was easy, the best I have seen. Simple & Billiant. The automatic setup was easy; though be prepared to be blown out of the room by the loudest white noise test you will ever hear. Speaker phase is checked also and after reversing the polarity on the centres it was off to listening and viewing.
Wow! I put in Master and Commander and the first battle scene was just a revelation. The power of the whole scene was amazing, the Wharfdales have sufficient grunt to vibrate our listening sofa, and yet the bass was extremely clean in comparison to the Denon 2808, yet that was not the best, it was the mid/high where the splintering wood could be heard raining down on the deck in absolute detail. I just sat amazed through the whole film with a revelation of the video clarity, the detail was superb, but it was the sound, the sound: Musical! The Cambridge Audio does everything musically!
These are only first impressions, but so far I have no regrets of a listening audition vs reviews, the Cambridge Audio 551R is a superb AV receiver especially at the price. I know it is subjective, but the Krix/Cambridge vs Paradigm/Yamaha is no contest, the Krix/Cambridge wins hands down and much cheaper. There is also the future prospect of bi-amping the Krix as I am only running 5.1. and that alternative is just a button on the menu plus cables, and its functional....can't wait.
Hope this ok for a first review, as you can see I am impressed.
