Analog frequency response with signal processing:
–0.46 dB at 10 Hz
–0.16 dB at 20 Hz
–0.37 dB at 20 kHz
–59.26 dB at 50 kHz

This graph shows that the SR7007’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 124.3 watts and 1 percent distortion at 143.2 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 205.1 watts and 1 percent distortion at 225.4 watts.

Response from the multichan- nel input to the speaker output measures –0.15 decibels at 10 hertz, –0.04 dB at 20 Hz, –0.10 dB at 20 kilohertz, and –3.33 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.010 percent at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –76.65 dB left to right and –76.77 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –98.75 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.10 dB at 20 Hz and –0.28 dB at 20 kHz. The center channel measures –0.10 dB at 20 Hz and –0.28 dB at 20 kHz, and the left surround channel measures –0.10 dB at 20 Hz and –0.21 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is –0.02 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 118 Hz and the upper 6-dB down point at 121 Hz.—MJP

Video Test Bench
The Marantz passed all of our standard tests with only one minor hiccup. In the SD tests (480i input), the picture initially flickered off every few seconds. After a minute or so the flickering stopped and did not recur.—TJN

Great review

One other feature available on the top-line model is the "Hybrid PLL Jitter Reducer." This is mentioned in the manual, so I contacted Marantz for more information and a friendly rep explained that it operates on all digital inputs and is only available on the SR7007.

Marantz Stays Competitive

Submitted by htroig on September 15, 2012 - 7:29am.

Thanks for the review of the Marantz. I have liked their products since the late 1970's, but now is when I can afford them.

I have the SR5005 reciver and it is being used as a preamp. What do you recommend as an upgrade for my preamp functionality, the SR5007 reciever or the AV7005 preamp?

Thanks.

Appreciate your Marantz reviews

I haven't heard the SR7007 yet, but I've owned the SR6006 now for the past few months. For music, I find that it sounds better and creates a more stable stereo image than some much more expensive two-channel gear I've previously used. Thanks again.

Lagging behind in Audyssey implementation

Submitted by GFelizardo on September 18, 2012 - 11:20am.

I can't believe Marantz would AGAIN use Audyssey MultiQ XT in a top of the line model. I first used XT in my Onkyo TX-SR805 FIVE YEARS AGO. XT32 is the new standard. My current Marantz AV7005 also has XT - looking at the specs of the new Marantz receivers and preamps, there is NO compelling reason to change, unless I want to pay $3K for the AV8007. Audyssey XT32 is available on Onkyo/Integra receivers and preamps starting at $1100. Why would I pay for a $3000 preamp to get XT32?
I know Audyssey implementation is not the only factor in sound quality, but XT32 is a big jump from plain XT. I would compare it to listening to my old receiver without room correction, to installing my Onkyo 805 with XT.
I'm disappointed that Mark kind of minimized that the SR7007 had only Audyssey MultiQ XT.

how would it cope with B&W cm series 5.1

Submitted by mgida on October 15, 2012 - 3:45pm.

Hi guys,
to be more precise here are the infos:

- B&W set Cm8/Cm1/CmC/Asw10cm
- Room 20x16x8 ft or 6x5x2.4m
- Purpose music/movies 50/50
- Volume capacity usage max 50%.

Would this avr cover my needs which are more
quality oriented than quantity i.e. pureness vs. loudness

I almost went for a Yamaha a2010 or a3010, but the reviews and the matching (warm sound)with B&W has really raised my interest for this AVR.
One more thing, would it be out of question to consider the weaker SR6007??

I would really appreciate your feedback as I am stock in this sea of choices. I definately do not want a bi-amp, at least for the time being.

Many thanks in advance
MG

Video performance on SR5007?

Submitted by pete1 on November 28, 2012 - 12:32pm.

I'd love to have the SR7007 based on Mark's review but my budget only allows the price point of the SR5007. Is the video performance of the SR5007 the same as SR7007? I use an external amp for the front L/C/R channels so amplification is not a concern.

Reviews of Denon AVR-3313CI and Marantz SR-5007

Submitted by mbroyles on January 20, 2013 - 2:29pm.

Are you guys planning to review the Denon AVR-3313CI (MSRP $1,200) and/or the Marantz SR-5007 (MSRP $850)? It would be great to be able to compare these two receivers to the SR-7007 and determine if SR-7007 is worth spending the extra money? These three receivers seems to be of similar pedigree. Thanks.
