Warm, punchy, not without subtlty, good bass muscle and heft, excellent soundstaging, good ariness, powerful amp, drives my near-full range, true 4-ohm (moderately-reactive) speakers with aplomb. Small footprint Perhaps will make a good pre/pro.

Not that much treble extension, some timbral smearing, just a touch of abrasiveness or shrillness in the upper mids when turned up but most problematic of all is the bass that will thrust, but not perry.

I will compare to my Luxman receiver whose sonic signature has been permanently wired into my head having bought it in the early 90's, but which recently passed away due to a mysterious illnesses....(a moment of silence, please). Mind you the Lux originally listed at $1,600 - more than twice the 540r v2. I bought the 540 as a stop-gap remedy for music and movies till I could afford separates again - possibly end up using it as a pre/pro, or relegate it to the back seat of my system for movies only in a HT pass-thru or something if that doesn't work out. I bought the factory-refurbished 540 from Audio Advisor for $400. It worked perfectly and I can recommend AA.
The sound is warm, reasonably detailed and punchy, but there is a combination of a slight timbral veiling through the mids, and the bass, which, while dynamic and with plenty of heft, only offers below-average pacing, which is, in the long run, a bit too uninvolving to make this the center-piece of a discerning system - (though, to be fair, expecting to find the anchor for such a system for the going rate of $400 is pretty much a pipe dream, I have to admit). That's the one Achilles' heel of this unit's sound. Punchy and dynamic, yes - in fact when I heard Intrada's new release of Jerry Goldsmith's score to Alien, I know well that the fiercely-plucked strings are designed to catch you off-guard. I knew what was coming - and I still flinched - repeatedly! Definitely superior to the Lux, here. But, full-fledged rthyms challenge it - ask it to cha-cha-cha and it's more likely to chug-chug-chug. This is a strong amp that will play loud without significant compression or solid-state glare or grain. Though a touch of shrillness could be heard when turned up, satisfying levels could be reached without any intrusion, but I mostly preferr the volume down.
Obtw, one British website says the v3 exhibited a bit of hardness with the volume turned up that the v2 didn't have. I have not seen any corroberrating info before or since, and although I can't confirm it myself, I considered it significant. The amp for the v3 was redesigned by Cambridge.

I love the OSD set-up menu, brilliant feature for an amp of this price.
plenty of current, never have problems powering high volumes when needed/wanted.
build quality A+
looks more expensive than it is

remote function is sometimes a tad trivial. sometimes takes several presses of a buttion with the remote pointed directly at the amp for it to recieve the command.

This is a brilliant amp for the money. i have been slowly upgrading every component in my system and decided on this amp. when i first purchased it, it was running through incredibly cheap speakers but i thought i still sounded great. I have since purchased KEF 2way floorstanding speakers and run them bi wired. The clarity is amazing! it is like nothing I have ever owned. i know this is far from hi-end audio but to me it sound brilliant. I have found that letting the amp warm up for say 20mins before listening yields a much better sound. i try to leave it swirched on now when i can as to keep it warmed up so it always sounds its best.

Opens up a whole new dimension in sound! Each individual channel can be easily adjusted.

More than excellent sound quality.

Very fiddly to set up initially, watch out for SACD/DVD-A's with only 4 channels!

Awesome sound experience - bit overwhelming listening to for too long.

Cambridge Audio Azur 540C Version 2 (£269)

an old adage - what's better than one cake? answer two cakes!
and what's better than two channels? - 5.1 channels! which is what the hifi industry would have us believe, and some are trying really hard to convince us!

Having used SACD's in a stereo player up till recently, hoping to gain some 24bit quality on a budget, I was still not convinced, so decided to try for the full monty - ok if i don't like it everything could be returned within x amount of days as is Richer sounds consumer- friendly policy for the adventurous audiophile not wishing/worrying about dropping a clanger and be stuck with something they hate - it works, I am a loyal customer!

The 540C v2 is certainly a big step in the right direction, using a DVD 89 player (£199- handles SACD/DVD-Audio/CD), once you have connected it all up it the playback mode (stereo, 5.1 whatever) needs to be configured on a TV screen, so connection to the TV is essential for setting up. Once done, you need to make sure you feed it with a genuine 5.1 channel disc, as some recordings play only 4 channels with no centre speaker or sub channel (spent half a day working that out! - every wiring configuration you can imagine). I had 4 redundant Heybrook HB2 speakers to hand and now each connected together with Kimber 4TC cable are an integral part of my hifi/surround system, plus a Monitor Audio Bronze centre speaker, the closest match I could find, now I may get a sub, but the bass produced is more than adequate so maybe not.

The sound from this system is absolutely amazing, each channel clearly defined, it brings the music into a new dimension - "Brothers in Arms" like you've never heard it before. The 540C has amazing quality, not quite as good as my Cyrus 2 but it passes with flying colours, I can highly recommend the surround sound as an extension to my hifi system, and another string to its bow is that with aforementioned telly live concerts are an experience - I swear I was sitting on stage with Led Zeppelin during their acoustic set, instead of the back of the auditorium. I still have more films and sounds to experience, so far well impressed!

Looks hi-end. Those with tin-ears will think they've bought something special.
Decent mid-forward sound.

Lack of detail in lower ranges.
Overpriced.

I don't understand the positive reviews. It's a nice-looking, high-end appearing, very average multi-channel receiver. It might actually sound OK with cheap speakers or a low-end sub. But for those looking for a little detail with their low-end, keep searching. Though you won't find a "loudness" button here, it's presence is felt in spirit. Bass is fat, slow, lazy, and sluggish. Sometimes it's not even there at all, incompletely, lacking any sense of rhythm, the worst pacing I've ever heard.

As far as British "mid-forward" sound goes, I guess this is it... mids are pleasant enough and highs avoid being shrill. But then the fat sluggish bass is so over-emphasised... which I could deal with if it were detailed.

And at $699... there are so many far far far better options. This is low-end dressed for the high-end. Weak, not a condender.

The remote control seems to be nice at first, nice to touch. aluminium finish. and heavy. But when used it has a bad reception from the unit. you have to point very well into the amp to get communication. other than this, I love this amp.

I love music. and I love movies. I had a 2.1 stereo system made of a pioneer 30w integrated amp. made 10 years ago. and a pair of B&W 603 s3 speakers + 1 B&W ASW sub. It was Ok buy I wanted surround sound to get out of my mobies, no just stereo. I had the oportunity to listen to NADs, Rotels, Sonys, Yamahas, Pioneers and other pro stuff at studio recordigs. Ths cambridge Audio 450R V2 is great. my B&W sound VERY different from before the azur amp. I can listen detail, smooth mediums and deep bass. It can handle a big room, mine is 8 meters long (26 feets). As both B&W and Cambridge ar known to be both warm, I was worred about my system to be too much warm. But its not, it has detail.
I've been listening to classical and Jazz music and it sound nice, the strings are smooth but have detail at the same time. Jazz sounds good too.
Hardware department is ok with this unit. very solid. It's very cheep to buy.

As I live in Argentina (south america for those of you who dont know), I went to the CA web page and found the CA reps here in Buenos Aires. I mailed them and got a reply very fast. They send me to a dealer near home so I cound play and listen the amp. and so I did. hey where very kind. Custom service is great.

Great sound quality
Power (80 watts x 6 seems very underated)
Good dynamics , Great build quality for price.

Only 6.1 not 7.1 ...not a big deal to me .
Will only run 8ohms
No 12v trigger .
No HDMI upconversion ... (HDCP will pass thru component anyway according to Sony)

I purchased this soley based on written reviews size (only 4 inches tall) and color(silver),not having actually listened to it at all. So when I received it I was impressed with the box and overall build quality for only $699 retail. It really has an overall better sound quality than my previous Denon 2805 ,more dynamics , better capacitors? toroidal transformer? I believe it must be something extra to give something so small a noticable difference in sound. I will be adding an amp or two to this and using it primarily as a pre/pro , but don't let that stop you from just using it as an receiver it has the ability to drive most speakers to high levels in an average size room. For about $500 this is one to audition if you can . Solid remote too, but not programable. Highly recommended.

Lovely Sound Quality. Build Quality Unassuming looks Remote Control

Manual, it is useless.

I had been looking for an AV amp that could also deliver the sound quality that I required. I'm using a pair of Linn Katan's as my primary stereo speakers with a REL subwoofer. I have to say that the two cahnnel sound is fantastic. Sound stage is spot on with lovely musical quality that I had yet to hear from a A/V amp. Hard to believe at this price. I didn't find setting up to be too much of an issue and I agree with the other reviewers, the manual is a waste of paper. Don't understand how they can skip on such an important item. Half the pleasure of owning these products is having the text to read. Maybe I'm different but heh I like reading the technical stuff. My DVD player is an Onkyo SP501. Suits the sound well. I no longer have a seperate CD player as I have found the DVD provides excellent sound quality. I also have a Record deck linked through a NAD phono pre-amp. Again the sound stage is superb. The lack of a dedicated two channel input maybe an issue to some but try it you'll be surprised at just how good the amp handles two channel sound.

Sound quality Build quality Torroidal Looks nice

Worthless manual No way to access information Difficult to set up, esp for music No 2-ch direct-in No OSD (I don't need it, but many might)

Not for newbies, but a solid value for those seeking sound quality and are willing to work a little for it... I bought this as a budget band-aid (my refurb Marantz died) until I could go back to a high-end receiver or separates... but I've become very attached to it based solely on its music performance. But getting there wasn't easy. The manual has exactly ZERO information in it... furthermore, CA has recently disabled their online feedback / forum / email... so you are really on your own to figure out setup, via trial and error... it is very bare-bones (that's good), and yet there are too many DSPs arranged in a confusing manner (that's bad)... also, there is no 2-ch 'Analog Direct In' (a deal-breaker for some), so any 2-channel input necessarily goes thru DSP and engages the sub... the workaround would be to use the fronts of the 5.1 inputs, but that's only if you don't need multi-ch DVDA / SACD... not a problem for me, as I listen to 2-ch sources in DPL2 Music with the center off... otherwise I need the multi-in's for a universal player. Suffice to say if you're willing to experiment, it will deliver quality. It should also be noted that clicks and other issues mentioned in the first couple reviews here have been resolved some time ago... however, there is the lingering issue of digital synch delay at the very beginning of discs -- but apparently this will never go away with the Cirrus chips (widely used by many mfr's)... not a concern to me, all my music inputs are analog. It has never taken me so long to set up an AVR (I do em all the time for friends), but I'm glad I hung in there with this piece... the above might sound like a lot of complaints, but the effort was worth it... it sounds that good!... music is smooth and detailed, somewhat like the Marantz but a little more laid back (I giive Marantz the edge here)... movies have never sounded better... no way to know, but I wouldn't be surprised to learn that better than average Op-Amps reside in the 540. Build quality at this price point is ridiculously good (though it is mfr'd in Malaysia, unlike their 2-ch gear)... torroidal transformer, gold connectors, solid speaker terminals, supplied connector caps, handsome solid remote. I can't comment on video switching, as I hook all sources directly to the TV. I'll likely go back to a Marantz someday, if only for more connections and greater processing power... but -- If you a have modest system, few sources... If you are obsessed with sound quality... If you don't mind rolling up your sleeves and getting dirty... If you have only $650 to spend... You can't do better than this little 540R. This is their first AVR, it's been out a couple years... its successor may be a little more expansive, may offer a little more power... but if that's so, then it will probably cost more too.

Wonderful sound in both home theatre and audio 2 channel music listening. Warm and rich sound. 2 channel sound is warm and efortless, not muted as many other a/v receivers. Style and construction is top notch and very attractive.

The manual does not contain the details and content that one would expect from a quality piece. The markings on the rear connections are difficult to read.

Wow, I thought the only way to get a highly musical A/V Receiver was to either get an NAD or spent more than $1000 for one. Well seeing that I already have the NAD 742 setup in my bedroom I was in the market for something with more power but had to be just as musical as the NAD. The CA 540R really hit the mark. It is a terrific sounding in 2 channel and is such a capable receiver that it is amazing how it stands apart from everything in it's price range. It delivers eveything that I like about my NAD742, just more of it. More warmth, more effortless sound, etc. I have listened more costly examples from Marantz and Denons but they failed to deliver the sound quality. This receiver delivers a warm, clean sound. It appears to drive my Mordant Short 906s floorstands effortlessly without any sloppy bass. I would recommend this to anyone who is concerned with musical quality of their home theatre system. I was soo unimpressed with some of the a/v receivers musical capability that I was prepared to separate the home theatre and 2 channel music requirement into two systems. The CA has proven that it could deliver a high quality sound and home theatre all in one package.

I was looking for the 640A on a Sunday and as I looked through the mid sized box store that had your typical Sony Yamaha junk, I saw the Azur 540r tucked in a corner ready to be liquidated. $590 CDN!! Ok I have zero interst in surround but this was great. I have 2 B&W 601 S2 hooked up and after this thing broke in it sounded better and better. I will have to buy a pre-amp for my B&O Beogram RX which I use ALL the time and yes I buy new records. The amp brings out the best in good speakers and and it is true speaker possition seems to disapear and mucis is fun to listen to again. The controls are sstrait forward and the design respectable. Yes this is better then a $2000 Jap box. Plus easy to hook up and use. Hefty weight sold remote. This system stands out. How many people do we know watch their DVDs on Pro Logic in a $30,000 home theater because they can't figure it out. This is worth every dime, run, don't walk and get one. You will want to get good speakers for this, Brits make the best speakers as do Canadians I would recommend matching speakers for all channels except sub.
