Pioneer Elite SC-07 A/V Receiver Review

[admin]

The Pioneer SC-07 A/V receiver is armed with all of the latest decoding and processing, making it a capable product for next generation high definition audio and video. Although the SC-07 didn't fare well on the bench when tested with 4-ohm loads, it proved to hold up quite well on real world 4-ohm speaker systems driving musical content instead of continuous test tones and only gave up some of its composure as the volume levels were increased. I found MCACC to be quite a useful tool and ease of setup and operation of the SC-07 were strong points in a sea of overly complex A/V receivers. If you're a Pioneer fan, you will probably be quite satisfied with this receiver from a performance and operational standpoint. Although it isn't class leading, it can serve well in an upscale home theater system if used within its design limits.

The SC-07 was a bit limited in crossover options with the following increments: 50, 80, 100, 150, 200Hz.

Ive never understood why their upper level avrs lack more control over this?

Driving 4-ohm loads was an entirely different story. The SC-07 simply fell apart when running full bandwidth (20Hz to 20kHz) continuous power measurements. As I tested at frequencies above 5kHz with only 1 channel driven, the internal cooling fan would instantly come on right before the receiver would go into gross distortion and shut down at levels above 100 watts. With two-channels driven, I was able to squeeze out a clean 150wpc at less than 0.5% THD. Anything higher would again run the amps into gross distortion and shut off the receiver. I was a bit perplexed in how the receiver managed to better cope with 2 channels driven over 1 and could only surmise that it had something to do with symmetrical load balancing on the power supply. How this receiver was awarded the THX Ultra2 rating was a bit perplexing to me.

I beleive ive read a couple of articles that stated class d measuements would be skewed if interpruted the same way as tradtional class a/b is there any truth to that. (iirc it had to do with harmonic vs inharmoic dist) Its does seem strange that the ULTRA2 rating was acheived>

Although the SC-07 didn't fare well on the bench when tested with 4-ohm loads, it proved to hold up quite well on real world 4-ohm speaker systems driving musical content instead of continuous test tones and only gave up some of its composure as the volume levels were increased. As a result, I'd cautiously recommend using this receiver with highly efficient 4-ohm speakers.

Would you recommend it for use with 4ohm speakers?

The SC-07 has DLNA media client with FLAC support for those wishing to stream music from a PC or other Internet source.

Did you get a chance to compare this version to the one on the 94?

Disappointing. The VSX-94TXH seems to be a better overall receiver that this one is, and it was cheaper.

Without a precondition filter, I could not accurately do an FFT distortion analysis for the reasons stated in my review. The inability of this receiver to drive a 4 ohm load continuously at full bandwidth is independent of this issue and a result of one or all three reasons I stated in the review.

THX doesn't do full bandwidth continuous power tests.

THX certification for amplifiers only guarantees that amplifier voltage and current are sufficient to play any and all program material through a THX Certified speaker (capable of 105dB peaks, minimum 3.2 ohm nominal impedance, minimum 89dB sensitivity) to 105dB peaks in a 3,000 cubic foot room (for Ultra2).

What about upgradeability?

I recently tried a Pioneer Elite DV-58AV SACD/DVD-A player, which needed a firmware update. I called customer support and they said I had to SHIP the unit to Pioneer for the firmware!!!

For a freaking simple firmware?

Oppo had the same issues (some music tracks skipping) and they fixed it with a firmware you can just download on the website.

But Pioneer requires the unit to be shipped?

I have no respect for Pioneer.

I just purchased this receiver to replace the TWO Integra 8.9's I had to return due to defects.
They were to replace my old Denon 4806.

I bought it at Best Buy for $1,799.99.

It's a gorgeous piece of equipment, but not as heavy as the Denon or the Integra's. Do "ICE" amps weigh less?

I was disappointed to find out that you cannot upconvert hdmi signals to 1080p, but that didn't stop me from buying it. I felt that at this price point, it was a great deal.

I have it connected to the Axiom Epic 80 4ohm home theatre speakers and so far it does just fine.
The front speakers are bi-amped and sound great. I've noticed different sounds in soundtracks I never heard before with my old Denon.

I haven't really cranked it way up yet, but at moderate to high levels I did not notice any clipping or anything else unusual. I'm going to test it later at some higher levels to see how it does.

What would be the best method to test this receivers amp at higher loads? Settings, duration, levels, content...etc?

If it does not perform as it should, I'll just return it.

Incidently, the Integra did not do well with the 4 ohm load at all, that is the one that actually played surround sound. One of the reviews I read about the 8.9 is that it cuts wattage from 140 to 60 for 4ohm loads to protect the circuit.
Pretty lame "feature", especially since they make no mention of it in any of their literature.

ONE more thing please, do you guys have any recommendations, besides Integra or Onkyo, should I return this unit? I'd really like to have something made to drive 4 ohm loads and that does video upscaling.

Thanks!

If you're happy with its performance, why change it? Bench tests are usually much harder than real world test conditions.

The current protection circuit on the Integra tripped during ACD test which isn't a very realistic test anyways. That is a really good receiver as well and in real world should deliver decent power output.

If you don't feel the Pio amp is straining and you like it, I wouldn't fix something that isn't broken.

Currently there are NO products on the market that I know of that can take 1080p from component video and pass it thru HDMI as 1080p. So that comment in my review also applies to the Yamaha RX-Z7 and $7500 Denon AVP Pre/Pro!

Gene,

I own the sc-05 (sc-07's sister) but would like to get the best sound from it given that I do not have the ear or currently have the technical ability to tweak it like yourself. You mentioned an omnidirectional mic with a long nose to potentailly acheive more accurate calibration. Could you recommend one?

I just finished the Pioneer calibration using my old Denon 4806 microphone and the results were quite different. I don't know if they're better or not, just different. The prominent difference between using the cheap little plastic Pioneer mic and the Denon mic, were levels. With the Pioneer mic, most of the speaker levels were set between -3.0 and -5.0. The Denon set most of the levels around 0.0. Does this mean that the Denon mic is not as sensitive?Distances were all within a couple of inches of one another. Both settings sound fine and I don't think the use of a better mic, unless your talking professional grade stuff, will make much of a difference.

I must say that after playing a little bit of Mr. & Mrs. Smith at fairly high levels, the Pioneer didn't blink and the sound was great. I had to adjust the center speaker down a little. It was just too bright and loud. Both setups set the center to "Large", but I think it needs to be set to small. I haven't figured out how to do that yet.

For the most part, I'm very satisfied with the Pioneer so far. Besides, I'm over the high end stuff. Six months to a year from now, most of it will be obsolete anyway...lol.

Mics are calibrated for specific applications, you can't just use Denon mic on a Pio AVR and expect it to be properly calibrated.[quote=TABCON;498329]I just finished the Pioneer calibration using my old Denon 4806 microphone and the results were quite different.
