Marantz AV8003 AV Preamplifier Reviewed

Marantz pulled out all the stops when they made the AV8003 AV preamp. Based on the SR8003 receiver platform they pulled out the amp section and added balanced outputs to allow this piece to handle even ultra high-end theaters. While now replaced by the AV7005 this is still a solid unit and those interested in it can read Brian Kahn's full review here.

marantz_av8003.jpgThe AV8003 signals Marantz's re-emergence into the ultra-competitive AV separates market. At $2,599 the AV8003 is one of the less expensive surround sound processors and is positioned to attract those who are on the verge of buying separates or considering one of today's uber-receivers but who prioritize sound quality over bells and whistles. Utilizing a separate processor and amplifier allows the user to improve the quality of equipment over that which is offered by most receivers. An added benefit is that when the processing technologies change so much that a new processor is needed, you can still keep your amplifier. This, theoretically reduces the cost and waste associated with upgrading your equipment.

The AV8003 is housed in an aesthetically pleasing chassis with rounded corners and a clean front panel that features a large display window above a drop down door. The window is flanked by a pair of large knobs that control input selection and volume. Noticeably absent are the plethora of initials and symbols which are instead discreetly places on top of the front panel. Looking inside one can see the heavy copper plated steel chassis with an enclosed torioidal transformer with all the parts carefully laid out to maximize performance. The AV8003 is feature laden and can even be hooked up to your computer network to stream pictures, audio and video. This three zone processor also features more of the features that one might expect to find in a new surround processor including HDMI 1.3 support, DTS-HD Master Audio, Dolby True HD, HD radio tuner, XM and Sirius ready, Anchor Bay Technologies video scaling and Audyssey room correction. I've left out several features as there are simply too many to list in this article. Trust me, this sucker is packed with technology.

Despite the plethora of features the intent of the AV8003 was not to be a feature showcase but rather provide class beating performance. There are many other products out there with even more features, one only has to look at Marantz's sister company Denon for such products, but features for features sake does not always mean a benefit for the user. With the Marantz AV8003 the designers made many conscious decisions of what to include and what to dump and these decisions were primarily based upon performance. While I has some difficulty setting up the networking aspect of the AV8003, the rest of the setup was straightforward. Marantz has achieved its intent with this piece. The AV8003 performed extremely well with both video and audio. One would most likely have to spend multiples of the AV8003's price in order to obtain significantly better performance.

Competition and Comparison
Be sure to compare Marantz's AV8003 against its competition by reading our reviews for the
Cary Audio Design 11a home theater processor and the Parasound P7 preamplifier.  There is also information available in our AV Preamp section, as well as on our Marantz brand page.

High Points
• The AV8003's audio/video performance rivals units costing several times its price.

The ability to receive network media, HD, XM and Sirius radio all in
one unit is really sweet. Seemingly every receiver would be able to
receive these sources but oddly they don't when the Marantz does.
• The ability to decode every surround sound codec (even the new advanced ones).

Low Points
• The glass fiber rounded front panel pieces feel like inexpensive plastic.
• The AV8003 can only handle seven external sources, not nearly enough for my main theater system.
• Setup of networking capabilities can be complex for the non-IT oriented consumer.


Marantz AV8003 is easy to recommend for one seeking better performance
than what a receiver can offer but who is not yet ready to invest
$10,000 in a single component. The Marantz AV8003 has all the bells and
whistles that today's buyer is conditioned to look for plus the features
necessary to easily integrate it into a complex system. That, coupled
with its solid performance across the board, from stereo to DTS HD
Master Audio make this piece an easy recommendation for anyone who needs
today's feature set but demands superior performance.

networking capabilities are a nice touch and I would like to see them
expanded. As they are now, one can use the Marantz to view family photos
and video stored on a computer and as a music server. Even with all of
these features the AV8003 doesn't forget its main purpose, while
watching movies or listening to music, it has been able to reproduce an
involving and convincing sound field.
