Duffinator,
I've been discussing differences between the Denon AVR-3805 and Arcam AVR300 over at avforums.com.
I eventually got chance to take a good listen to both, using my own speakers, and posted the follow report, hope it's useful:
Hi all,
I said that once I’d spent some time reviewing receivers, and hopefully made a purchase, I’d report the details. This is a *very* long mail , but hopefully of use to some people. Details of the kit, and what I auditioned, follow:
My speakers (all designs from Wilmslow Audio):
Front: Nemesis – Scan Speak bass and treble. Excellent treble and crisp, if slightly thin, bass.
Centre: Gemini – Morel bass and treble. Warm, pleasing sound, if a little ‘muddy’. Probably not that well matched to the fronts, but a very pleasant listen.
Surround: Midas – Seas Excel bass and Vifa treble. Good clean crisp sound, treble not quite as good as the Nemesis, and bass obviously weaker due to smaller bass drivers.
Kit tested (and RRPs):
Denon DVD-3910 – 900GBP
Denon AVR-3805 – 1000GBP
Arcam AVR-300 – 1300GBP
Cyrus 8vs – 800GBP
Cyrus CD6 – 600GBP
The street prices of the Denon gear is usually a bit less, I just included the prices to indicate the kind of level of bits I was testing.
Testing:
The dealer set up my speakers on the Denon AVR-3805, and we ran through a few movie tests (DVDs played by the Denon DVD-3910). My overall impression was positive – clear, crisp, good effect of sound moving around you, and it was very engaging.
It produces quite an ‘in your face’ sound, which I felt could get a bit fatiguing, but it certainly impresses.
We then tried CD playback, again using the Denon DVD-3910, with its DAC, rather than that of the receiver.
To be blunt – it was very poor. I’ve previously heard the front speakers on an old stereo amp, and a Pioneer AX10Ai (RRP 3000GBP). Obviously, you couldn’t expect the AVR-3805 to be comparable, but the sound was completely lifeless – poor vocals, harsh treble, and was just generally dull and unengaging.
We then switched over to the Arcam AVR-300, with the Denon DVD-3910 again supplying sound via its DAC.
The improvements were huge, not on a par with the Pioneer, but more than acceptable, if a little restrained.
After some discussion, the dealer suggested I compared a good stereo amp and CD player, and hooked the Cyrus units to my front speakers (using the DAC on the Cyrus CD player).
The difference was staggering, much fuller bass, clearer vocals, and tighter treble. It was unquestionably better in every area (admittedly, no surprise there).
We then replaced the Cyrus stereo amp with the Arcam receiver, and used the Cyrus CD6 instead of the Denon DVD-3910, again using the DAC on the player.
When playing music such as acoustic guitar + female vocals (Carina Round, KT Tunstall, some Rilo Kiley tracks), I felt that the difference between the Arcam and the Cyrus was detectable, but small. For more challenging material – e.g. loud Pearl Jam tracks – the difference was far more noticeable.
Conclusions:
If you are after a surround receiver for movie use only, don’t care about stereo music, and don’t mind (or like) ‘in your face’ sound, the choice is a no-brainer – the Denon AVR-3805, with a price at least 500GBP less than the Arcam, wins hands down.
If you are after a surround receiver that will handle movies, but also live with your music collection it really has to be the Arcam. The price difference is large, but the sound from the Arcam is very acceptable, but, IMHO, the sound from the Denon is not.
The dealer went through several other potential upgrades to improve the sound. He suggested that I could later add a stereo amp, and connect the pre-outs for the front speakers on the receiver to the amp. This would use the receiver to drive the centre and surround speakers, but only act as a processor for the fronts. Thus you’d get better results in stereo, and still get a surround setup. I'm aware that you could probably do this with the Denon receiver too.
He also noted that the DAC in the Arcam is much better than the DAC in the Denon DVD-3910 (and also in the Denon receiver). Thus, a coaxial digital connection from a cheap DVD or CD player would probably get reasonable sound, though would obviously be beaten by the DAC on a decent CD player such as the Cyrus.
I should also mention that all my speakers have split crossovers and can be bi-wired/bi-amped. Whilst we didn’t test either, the general consensus seems to be that bi-amping does yield an improvement, and the Arcam AVR-300 is capable of bi-amping the front speakers, even with a full 5.1 setup.
To sum up, if you can afford it, I think the Arcam AVR-300 is a pretty good starting point, and will allow movie reproduction, will not overly hamper a good CD player, and can be connected to a power amp (via pre-outs) in order to improve sound quality.
There was only one slight problem – the dealer didn’t have any units in stock! (I have placed an order though).
