This graph shows that the SR7008’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 122.5 watts and 1 percent distortion at 148.0 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 195.4 watts and 1 percent distortion at 216.8 watts.

Response from the multichannel input to the speaker output measures –0.06 decibels at 10 hertz, –0.01 dB at 20 Hz, –0.17 dB at 20 kilohertz, and –3.38 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.008 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 –62.97 dB left to right and –62.81 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –102.21 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.03 dB at 20 Hz and –0.21 dB at 20 kHz. The center channel measures –0.02 dB at 20 Hz and –0.19 dB at 20 kHz, and the left surround channel measures –0.02 dB at 20 Hz and –0.24 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.01 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
It’s rare for a product to pass all of our video tests, but the Marantz SR7008 did. Its upconversion quality from 480i and 1080i to 1080p was excellent, as was its performance on direct pass-through of a 1080p source (the clipping and resolution tests).—TJN

Great review! I recently purchased the latest Marantz SR5008, the sr7008 was a little out of my price range but this year the early entry models have both the HDAM and current feedback topology included so I thought it was a bargain. I've been testing my amps capabilities over the last few days and I strongly agree with you Mark about implementing Dynamic EQ and Dynamic volume at its Lowest setting. It just takes the edge off those really high dynamics, but you still get plenty of thump and feel every impact, without having your ears piercingly blown off! (test the scene near the end of Star Trek Into Darkness where Khan, Kirk and Scotty have a fight with 5 or 6 men aboard the ship and you will see what I mean)(Though I listened at -10, 75db, I don't know if you run all your tests there or at Reference)
Anyway, thanks to your reviews of this Receiver and the previous Marantz models that have reviewed, you really helped me pick the perfect Receiver I have been looking for.
Cheers

Amazing for a 27.5 pounds receiver!

- Nine amplifiers (125W)
- Audyssey MultEQ XT32. ...Sub EQ HT. ...LFC
- Fully loaded on the connection side (rear, with 3 HDMI outs)
- Very decent measurements (except for channel separation)
- Nice looking unit (front & rear)
- And it ain't an Onkyo TX-NR818 (the Marantz SR7008 is two grands)

Having the Audyssey XT32 on these units makes them a dream to calibrate. I use my Audyssey Pro Calibration kit to set them up and it gives and outstanding result.

I notice that the 7007 is now almost $1,000 cheaper than the 7008. If you don't need the extra channels that the 7008 provides, can someone tell me what are the big differences between the two? I mean, is XT32 that much better than XT (which I think could be upgraded to XT Pro, whatever that is)? Is there something more that's definitive? Thanks.
