How to Shop for an AV Receiver
With such a wide selection of A/V receivers on the market these days, it's difficult to know which model is right for you. Before getting into all of the tech specs and features, its important to first define how you will use this product.
A receiver serves as the “brains and brawn” of your home theater system. Pretty much all of the components in your system will interface with it to some extent and it is the main piece of gear that routes audio and video for you.
This article is a 7 step guide to choosing the right A/V receiver. Why only 7 steps? Because we were tired of the classic 10 step process and wanted to simplify and save everyone time... that and we really couldn't come up with three more.
Step 1: What video connections do you need?
Does your DVD
player or cable/satellite receiver use HDMI?
If so, you'll want to choose a receiver that has HDMI connectivity or you
will have to bypass the receiver and go directly to your TV to get the best
picture quality. Going HDMI also simplifies your connections so the back of your A/V rack doesn't wind up looking like mine pictured to the right :)
Most entry level displays only sport 1 or 2 HDMI inputs so it's usually a better idea to select an HDMI-enabled receiver. Remember HDMI is the only connection method the new high definition players (ie. HD DVD or Blu-ray) are allowed to use to send HD signals (>480p resolution) from the player to your display so don't settle for component video or lower resolution connection schemes. HDMI receivers have come way down in price and can be had as little as $249 so there is almost no excuse NOT to be buying an HDMI enabled receiver today. Although we haven't tested the latest round of Pioneer receivers, they seem to be the market leader in the $350-and-under price category and their new x18-series A/V receivers that debuted at CES 2008 look most impressive.
Step 2: What HDMI functionality do you need?
Not all HDMI receivers are created equally. It wasn't until recently that the latest version of HDMI (ver 1.3a) was supported by any hardware despite it was the "going forward" standard for 1080p Deep Color (12-bit) video and True-HD and DTS HD audio support. Only HDMI 1.3a can support all of the latest formats natively, but it doesn't mean you can't get by on the lower versions, especially if the price savings makes sense. If your display resolution is limited to 1080i then older versions of HDMI will work just fine. If you don't own a high definition DVD player but eventually plan to buy one down the road, make sure the receiver you choose has multi-channel audio support via HDMI so you can have the player send the lossless decoded high resolution PCM audio signal to the receiver for it to provide bass management and proper routing to your speakers. If you think Dolby Digital and DTS sounds good, wait until you hear True HD and DTS-HD on your favorite movie or concert video. If you want the cream of the crop, then get an A/V receiver with HDMI 1.3a Deep Color support and TrueHD and DTS HD audio decoding. These type of receivers start at around $800 and work up from there.
Step 3: Do you require external inputs and preamp outputs?
External multi-channel inputs are used for the purposes of connecting DVD-A and SACD and even some HD DVD and Blu-ray machines to play back high resolution audio. This can be cumbersome as it requires at least 6 RCA level interconnects between the player and receiver.
While most $300 and up receivers today have 7.1 multi-channel inputs, many of them do NOT have preamp outputs. Preamp outputs are a necessity if you plan on pairing your new receiver with a more powerful external amplifier. This is usually a good idea when mating a receiver with low impedance, low efficiency speaker systems. If somewhere down the road you plan on eventually purchasing an external amp for this purpose and you are choosing between two receivers both of which have preamp outputs and inputs and the basic features you need, buy the cheaper receiver. Separate multi-channel amps usually have more power than even the best receivers on the market. Don't assume even a reasonably costly receiver will have preamp outputs. Always check the back panel. We were quite surprised that Denon didn't include this feature on their excellent AVR-2308CI A/V Receiver which retails for $850.
Step 4: Do you need multi zone functionality?
If you plan on routing speakers throughout the house for multi zone audio, you need to make sure the receiver you select has such capabilities. Most receivers in the $500 and up price range offer at least one additional zone of audio. If this is an important feature to you, it's a good idea to choose a model that allows you to use some of the internal amplifiers of the receiver for this functionality. That way if you buy an audiophile power amp to use on your main speakers, you don't have to let the amplifiers in your receiver go to waste. Some of the best multi zone receivers we've tested have been from Denon and Yamaha (model RX-V661 and up). We especially like these because they allow you to reassign at least 4 channels to Zones 2 and 3.
Step 5: How much power do you need?
Are you party animal that likes to crank music at ear bleeding levels to impress your friends and really get everyone moving? If so, you will need a receiver with a hefty power supply - especially if you are running a multi-channel system in a largish room (over 3,000 ft^3). If your speakers are 4-ohm rated and have low sensitivity (<89 dB @ 1 watt), we recommend selecting a more powerful receiver that is rated to handle this. It's usually a safe bet that when buying a THX Ultra2 certified receiver, the power supply is up to the challenge. As a good rule of thumb, if a receiver has some heft to it (40lbs or greater) it will usually be robust enough to pump out some serious power. Onkyo has the lowest priced THX Ultra2 A/V receiver on the market – the TX-SR805 and it has quite a meaty amp section but it lacks some of the bells and whistles of its competitors. If you are looking for a bare bones HDMI-enabled powerhouse, this is a solid recommendation, otherwise expect to pay a little more to get a receiver with better upscaling features and audio streaming.
Bottom line is if you like to listen to music LOUD, don't skimp on power. Alternatively, if it's not in your budget to buy the more powerful receiver, at least choose one with preamp outputs so that down the road you can connect a more powerful external power amplifier. With the price of quality multi-channel amps from the likes of Emotiva (IE. their new XPA-2 and XPA-5 amplifiers) being priced as low as mid level receivers, power has never been more affordable. Be sure to check out our detailed measurements and analysis sections of our A/V Receiver reviews to see just how well they stack up when being put through our vigorous testing procedures.
Step 6: Do you need advanced bass management features?
In most cases the typical 80Hz global crossover setting and one subwoofer output will satisfy more users. However, more advanced users will prefer variable crossover settings per channel group and multiple independent subwoofer outputs. For the more advanced user, we suggest digging deeper to ensure that your receiver of choice truly does provide you the flexibility of connecting more than one subwoofer that has independent level and distance trims and will also give you the option of routing LFE and/or bass from all speakers set to 'Small'. There are several processors on the market that simply parallel out the main subwoofer output which limits your setup options. We have found Denon to be the leader in bass management flexibility but lately Yamaha, Onkyo and Marantz are catching up and offering multiple crossover selection per speaker groups, sub out with main speakers set to 'Large', and multiple subwoofer outputs, etc.

Step 7: Bonus Features - the icing on the cake
Ok you've got all of the core features needed for a good home theater. Now it's time to put the icing on the cake. Let's talk about bonus features.
connecting older 480i equipment such as a Laserdisc player or (gasp) a VCR, you
may want to select a receiver with video processing and upscaling. It's especially convenient to have a receiver
upscale all of your video sources to HDMI.
Keep in mind however that no matter how good the video processing
capabilities are on a receiver, they will frequently do a worse job of scaling
and upconverting than a dedicated HDMI enabled DVD player. Because of this, upscaling features built
into a receiver are mostly useful for older analog video sources. Keep a mindful eye on our HQV test results in our receiver reviews to determine just how well a particular receiver does these duties.
Auto Set-up and Equalization
These systems are usually a mixed blessing and almost never get all of the settings correct. But, the better ones can get you close and certainly all of them are better than not attempting to calibrate your system at all. Some companies such as Yamaha and Pioneer have their own auto setup systems called YPAO and MCAA, respectively. These generally do a good job of setting speaker level and distance, but we've found Audyssey to be a cut above the rest in getting your system to sound its best. Audyssey MultEQ can be found on receivers from Denon and Marantz as well as a handful of high-end processors.
XM Radio and Network Streaming
If you love the convenience of nearly infinite music channels and talk show selections and can stomach the massive amount of audio compression, than you may want to select a receiver with a built in XM tuner. If not, you can always add an outboard tuner in the future for around $100 or so.
Network streaming is really starting to take off in receivers and we really like what Yamaha has done here, especially if you are a MusicCAST owner. Denon has some nifty capabilities here as well and if you want music distributed wirelessly throughout your house, receivers from these guys are some of the top contenders.
Well there you have it. As you can deduce from this article, it all boils down to what level of HDMI connectivity you desire when choosing a receiver. At this point, budget A/V receivers ($250-$500) with basic HDMI splitter/repeater functionality will get you bare bone options, limited power and multi zone features. Stepping up to $900 or more will start getting you receivers with the latest audio decoding, basic video upconversion features and multi-zone audio support. Spending upwards of $1900 will get you those heavy THX Ultra2 certified receivers that will play louder and cleaner in larger listening spaces and have all of the video processing features as well as multi-zone and streaming audio support.
is no need to over-buy based on your needs, it's important to understand what
features you need in order to make your home theater function to your level of
expectations and provide years of hassle-free enjoyment. There are a lot of great choices out there so
take your time, do the research and ALWAYS purchase from an authorized retailer
that offers post sale product support.
Shopping for the best price isn't always the best option but we'll leave
that as a topic for another article.
