Marantz AV7005 Introduction

av7005.jpgA few weeks ago I joined the Audioholics forum and not much later I wrote a review for the Marantz AV7005 A/V processor, along with other some other equipment. When they approached me to rewrite my review for their website, I immediately said yes. So, here it is; my first official review! I sincerely hope you like it.

The AV7005 A/V processor and MM7055 Power Amplifier are Marantz’s new flagship products. I preordered them to replace my SR6003 AV Surround Receiver. As such, this review is focused quite a bit on comparing these units. If you already own Marantz products and are contemplating upgrading, this review is for you. I’ve also tried very hard to write this review from a consumer perspective. Trying to make up for a lack of hardware analysis frequently found in Audioholics reviews, I’ve concentrated on usability issues instead.

Every respectable home theater manufacturer seems to offer a Pre/Pro – multi channel amplifier combination nowadays. Marantz has had the AV8003 / MM8003 combination for quite some time now. Though respectable performing units, they are perhaps a bit too expensive for most of us and quite frankly, the AV8003 has become outdated.

av7005back.jpgMarantz seems to head into a new direction with their new A/V processor and power amplifiers. Allow me to make a bold statement: perhaps much like Emotiva is already doing (with a lower price tag). Having a Pre/Pro and a separate power amplifier offers a lot more than just better sound quality and a higher energy bill. It allows for a modular set up of your home theater. Just add speakers and MM7055 (5 channels) or MM7025 (2 channels) amps when your budget allows for it. Keep your multi channel power amplifiers and swap out your outdated A/V processor for a new one, whenever that new HDMI 1.7BS ultra high speed Holographic projection becomes a must have. So what exactly are the main differences between the AV7005 and AV8003? At first glance the AV7005’s updated “port view” design stands out, previously found only with their Reference Series products. Also, the AV7005 is a fully packed Internet connectivity unit and offers HDMI 1.4a 3D in/outputs. The AV7005 sports HDAM (Hyper-Dynamic Amplifier Module) discrete circuits and Current Feedback technologies which wasn’t found on their more costly AV8003 predecessor. There are some similarities between these units however. The AV7005 is packed with some of the same high-grade components of the AV8003 such as the same chassis (but steel instead of copper plated), and Marantz’s proprietary power transformer.

Sad clueless

I have found some details of your speakers.

The manufacturer classifies them as 6 ohm nominal which means absolutely nothing.

Here is a picture of your speakers.



From the design approach, those speakers have to be four ohm and I would bet less in places. That type of design layout is also associated very often with highly adverse phase angles.

That is not the type of speaker most receivers will drive well. I think you are very lucky the Integra does, at least for now. Personally I would be looking to provide robust external amplification, or you may well have to look for a new receiver sooner rather than later.

I bet your problem was that the Marantz could not drive that load, which does not surprise me.

I would measure the impedance curve and phase angles of those speakers.
My friend you are guessing which is sad. You have found an old picture of my old setup from 2005 without a clue as to the build or quality of my speakers. If you read my original post I stated my speakers are modified .Personally having built new crossovers for them with German mundorf parts and installing ceramic L-Pads which varies their total resistance. Having their sound pressure level tested and frequency responce by an independant source . I can tell you they **** on most manufactured speakers in the 10,000 dollar range. They out perform most B&W ‘s in all ab testing. My Old Gold Sony STRVA-3333ES Receiver played for 30,000 hours and is still going ,realy only using all its preouts since 2006.I only retired it to have more digital and net connections, so if what you say is correct it should have died years ago. I could go in to depth talking about sound stages but I get the feeling it would be a waste of time falling on deaf ears . As I originally stated everyone is entitled to an opinion and if you havn’t heard better than your Marantz that's just the way life goes. Dont threaten something you obviously have no clue about .Or as they say never judge a book by its cover.

Old pic , lots of changes since that time.

G'day,
That's a very old pic of the system back in 2005. Its been upgraded , tweeked and changed alot since then.The center speaker has been elevated to the ceiling , apart from being rewired with pure silver 99.9999 conductors from crosssover to drivers and down to amp,crossover modified like all other seven speakers with mundorf caps.Its ceiling mount is reinforced with 3 feet square by 2 inch thick MDF board above the plaster(this cuts down unwanted bass),above the ceiling.All my main speakers have ceramic L-Pads installed on their rears for tweeters and bass to vary their responce according to room accoustics, this by the way changes their nominal resistance my calculation makes them closer to 8 ohms rather than 6 ohms now. All my interconnects and speaker wiring have been changed since 2005. The front towers have come forwood about 1 foot also than that old pic and sound diffusers behind the towers have been improved internally and changed color. The large power amps sit ontop shelf with the Integra processor replacing the Gold sony AVR these days. Sorry guys I know what i listen to, I build the stuff..The extra $1000 I just spent was well worth it. cheers.

He was talking about the AV7005, that is a prepro, not an AVR.

So it is. I can't see how a pre/pro would do what he is talking about.

Mine and yours work perfectly.
