I got said review of SR 6004 today and I did some research of Marantz's amps. I posted yesterday:
"SR6004 won a 900 - 1300 euros receiver test in Finnish hi-fi magazine Hifimaailma (issue 7/2009).
The competition that got whipped consisted of Denon AVR-2310, NAD T 747, Onkyo TX-NR807, Pioneer VSX-LX52 and Yamaha RX-V1900."
The 6004 really shined in analog inputs
in source/pure direct
mode. S/N-ratio averaged 6 dB better in Marantz than in it's rivals, which is quite big difference. Difference betwenn Onkyo 807 and SR 6004 was 9dB, which is almost double the sound pressure (=10 dB difference doubles the sound pressure). The reviewer said that Marantz 6004 sounds a lot like their 2-channel amplifiers, so the stereo output is really nice for an av-receiver.
So a tip for Marantz owners: accoding to the review it's highly recommended to use analog inputs in every source where it's possible.
Digital input produce slightly more harsh and metallic sound in highs according to reviewer's taste.
The overall sound in both digital and analog inputs is highly controlled (bass control and extension was one of the best in review), clear and lively but not being fatiguing at all or too "in to your face". Reviewer really liked the sound of the amp (so does Legis
). Marantz had best upconverter for analog video signals.SR 6004 power ratings according to the review
8 ohms stereo RMS/dynamic: 130/150 watts.
8 ohms 5-channel RMS/dynamic: 94/98 watts.
Power ratings go in accodance with last 03 series' power ratings, although they are slighly lower in new 04 series... The reason for this difference can also be in the used measuring technique.
I also researched SR 5003 and SR 6003 amps a little. According to these reviews (SR 6003
and SR 5003
) of SR 5003 and 6003 one can see that both amps have nearly identical power output. Ergo: SR 5003 and 6003 use same/nearly same amplifiers.
Power rating of 5003:
2 channels driven continuosly into 8-ohm loads:
0.1% distortion at 153.1 watts
1 percent distortion at 171.3 watts.
Five channels driven continuously into 8-ohm loads:
0.1% distortion at 103.8 watts
1% distortion at 118.0 watts
Power rating of 6003:
8 ohm stereo: 130 watts of rated power. (THD% was not mentioned)
8 ohm 5-channel: 111 watts of rated power.
(These power ratings were taken from the websites mentioned in the last paragraph)
I highly suspect that also new SR 5004 and SR 6004 are very likely almost identical in respect of power output and sound quality, just like the older series is. 5004 and 6004 weight the same and inside of the amps look identical. Marantz's website also shows that they are nearly identical when you compare the two model with each other. http://www.marantz.com/
Where the 5004 and 6004 differ is that 5004 misses usb-post, couple digital inputs, one HDMI input and outputs and has different front panel.
If someone can compare 5004 and 6004 side by side, it would be really nice. I hope that some website puts the 5004 to test bench soon.
Sorry for long post EDIT:
Oh, and short summary of the rest of the amps' sound (best to worst, review used emphasis 50% on sound, 25% on video and 25% on features):
1) Marantz - read above
2) Onkyo: Sound was too laid back and not so interesting to listen to. Bass control was average but it lacked power at the lowest frequencies. Sound did not have much room. Good overall both in analog and digital inputs.
3) Pioneer: VSX-LX52: Had the clearest highs in the group, but sounded bit hard. Some records can sound fatiguing. Rhytmic response was good but bass lacked little oo the "emancipation". Best sound in digital input but loses to Marantz in analog inputs. Worst converters for analog video signals of the test.
4) Denon AVR-2310: Too bright and "clinical". bright recording sound really tight-bright and fatiguing. Stereo-image undefinied. Bass lacked power at the lowest octaves. Weak cotrol.
5) Yamaha RX-V1900: Fresh and bright sound, maybe little too bright. Brightness "fakes revealingness", amp is not too revealing after all. Weak stereo-imaging.
6) Nad T 747: Best streo-imaging in the group. Little harsh sound in highs.
What I deducted from the review, the list would go like this if the measured attribute were only sound quality (sorry for little confusion):
1) Marantz & Pioneer (Marantz is better when it's in it's best = analog input and source/pure direct mode, Pioneer is better in digital inputs)
5) Denon (!)
This is in many case much dependable of the reviewers taste though... Subjective listening test are not absolute thruth.Edit2
: And by the way, I read from user's manual that both sr5004 and sr6004 consume max. 650 watts of power
. If 6004 were to produce 70 watts more power (10 watts per channel) than 5004, this would also show in the power consumption. For the comparison sr5003 and sr6003 have max. power consumption of 600 watts, 50 watts lower than the new series
. This would indicate that the new series is little more powerful than the the old series... I doubt that the extra 50 watts are converted to heat(, meaning that the new series would be less energy efficient than the old series).
Again, sry for x-tra long post...
