HT Labs Measures

Two channels driven continuously into 8-ohm loads:
0.1% distortion at 127.9 watts
1% distortion at 153.2 watts

Five channels driven continuously into 8-ohm loads:
0.1% distortion at 75.9 watts
1% distortion at 92.0 watts

Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 71.3 watts
1% distortion at 83.4 watts

Analog frequency response in Pure Direct mode:
–0.14 dB at 10 Hz
–0.04 dB at 20 Hz
–0.08 dB at 20 kHz
–2.80 dB at 50 kHz

Analog frequency response with signal processing:
–0.44 dB at 10 Hz
–0.15 dB at 20 Hz
–0.43 dB at 20 kHz
–59.42 dB at 50 kHz

This graph shows that the SR6006’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 127.9 watts and 1 percent distortion at 153.2 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 156.8 watts and 1 percent distortion at 195.8 watts.

Response from the multichannel input to the speaker output measures –0.13 decibels at 10 hertz, –0.03 dB at 20 Hz, –0.07 dB at 20 kilohertz, and –2.87 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.005 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 –76.85 dB left to right and –76.78 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –110.24 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.10 dB at 20 Hz and –0.27 dB at 20 kHz. The center channel measures –0.09 dB at 20 Hz and –0.15 dB at 20 kHz, and the left surround channel measures –0.09 dB at 20 Hz and –0.10 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
In most respects, the Marantz SR6006 appears to be a near-clone of the Denon AVR-3312CI we reviewed last month—not surprising because the two brands are owned by the same parent company (D&M Holdings) and sell for comparable prices. The Marantz therefore turned in results identical to the Denon on our video bench tests, which are run HDMI in to HDMI out. It excelled in particular on the 2:2 deinterlacing tests—tests that have tripped up many of the AVRs we’ve tested. As with the Denon, the Marantz failed only the chroma resolution test, which indicated a major red rolloff on the highest horizontal resolution burst (only blue lines remained visible on the burst). However, this should not degrade most real-world program material

As with the Denon, the only snag was in accessing the somewhat confusing menus for setting up the video-output resolution and the way this is presented in the (CD-ROM) manual. The latter describes the setup procedure for four pages before it tells you how to access the setup menu itself. (Hint: You have to access the Input Setup submenu to set the output resolution, and it’s set separately for each input. —TJN

I do wish that HTM would be a little more current with its reviews. The SR6006 is being replaced next month by the SR6007. BTW, the Denon 3312 they reviewed a week ago is being replaced by the 3313 this month or next.

Last year I was also looking at AVRs and read a HTM review of an Onkyo...looked interesting so I checked it out on-line...I think I had to go to Onkyo's web site archieves to find the manufactures specs on it.

Same issue with TVs...

Come on guys, use your publishing clout to get review subjects as the come out, not when they are end-of-lifed.

I will never buy a Marantz ever ever again. Disregard all reviews other than this one. If given one I would not take it. Mine is the SR 6006. It is a massive pile of crap. You have been warned. Oh by the way, this is the second I have owned. The first broke within a week. Then I exchanged it thinking it was just a fluke.. I was wrong. I should have gotten something else.

I bought an SR8001 paid about $2K from a reputable dealer dealer. I did a lot of research but not enough. I believe in "you get what you pay for" I was proven wrong!!!

I would expect this to last for about 10 years or better. I guess I should have bought a McIntosh.

I bought the unit in 2006 and it worked great until about 2010. I don't abuse my equipment. The idiot light next to the power button started flashing. I did a little homework and checked the forums and found out I was not alone. I brought the unit into the dealer.... and what they did I don't know but it cost me $160. I brought it home and it worked for about a week and the unit started doing the same thing. I have lost all faith in Marantz and don't recommend anyone buy their products. It is like playing Russian Roulette. You don't know what you are going to get.

I have been looking for a new premium receiver and looked at this one and found there are issues with the power supplies.I looked in the forums. I will not roll the dice with Marantz again. I don't know about you but I work hard for my money.

Anyone have any suggestions?
