这儿仅仅提供SOUND and Vision杂志评测的部分结果，对每一个机型采用同一标准进行测试，所以之间功率是完全可以比较的。这儿仅列出1KHZ信号，每声道8欧姆的测试结果，其余结果请见该杂志网站。

品牌	标称功率	5声道实测功率	7声道实测功率
Onkyo875	7X140W	5 channels driven(8ohms):141 watts (21.5 dBW)	7 channels driven (8 ohms):128watts(21.1 dBW)
Denon 4308	7x140W	5 channels driven (8 ohms): 126 W (21 dBW)	7 channels driven (8 ohms): 111 W (20.5 dBW)
Pioneer 94TXH	7x 140w	5 channels driven (8 ohms): 84 W* (19.2 dBW)	7 channels driven (8 ohms): 61 W* (17.9 dBW)
Yamaha1800	7x130W	5 channels driven (8 ohms): 103 W (20.1 dBW)	7 channels driven (8 ohms): 55 W (17.4 dBW)
Integra 8.8	7x140W	5 channels driven (8 ohms): 121 W (20.8 dBW)	7 channels driven (8 ohms): 109 W (20.4 dBW)
Marantz 7002	7x110W	5 channels driven (8 ohms):93 watts (19.7dBW)	7channels driven (8 ohms): 83 watts (19.2 dBW)
Onkyo605	7x90W	5 channels driven (8 ohms): 85 W* (19.3 dBW)*	7 channels driven (8 ohms): 80 W* (19 dBW)*
Yamaha863	7X105W	5 channels driven (8 ohms): 45 W (16.5 dBW)	7 channels driven (8 ohms): 41 W (16.1 dBW)

*先锋比较奇怪连续输出122w10秒过后保护电路启动降为61瓦输出.音量也减了三分贝

以后有新的机型，我会陆续更新

如果是真的话,还是安桥厚道.[s:97]

有几款不是平级在比

默雷

雅马哈1800七声道连续输出只有55W?

jbl4312

雅马哈的怎么7声道功率只有5声道的一半？

看数字是没用的,各家的测量方法不一样,看看我前段时间写的这篇文章

安桥好样的

龙崖

安桥实在些。

lemondog325

用过安桥么？安桥水分最大，8欧根本达不到那个功率

标称不能说明问题。

看结果安桥实测和标称的差不多啊[s:61]

这个评测是SOUND and Vision杂志采用同一测试标准进行测试，都采用1KHZ，输入信号每声道8欧姆进行测试的，所以对各家都是公平的。这个表中的测试数据是我个人整理的，只有很少的一部分数据，不过我想也是大家最关心的，顺便说一声：第二栏为标称功率，请仔细看帖。

实际的功率测试结果比说什么拳拳到肉可信的多[s:30]

帖一个863的完全测试结果：（省得有人说测试不专业[s:30] ）

DOLBY DIGITAL PERFORMANCE
All data were obtained from various test DVDs using 16-bit dithered test signals, which set limits on measured distorting and noise performance. Reference input level is -20 dBFS, and reference output is 1 watt into 8 ohms. Volume setting for reference level was -3. All level trims at zero, except for subwoofer-related tests, all speakers were set to "large," subwoofer on. All are worst-case figures where applicable.

Output at clipping (1 kHz into 8/4 ohms)
1 channel driven: 77/111* W (18.9/20.5 dBW)
5 channels driven (8 ohms): 45 W (16.5 dBW)
6 channels driven (8 ohms): 41 W (16.1 dBW)
Distortion at 1 watt (THD+N, 1 kHz)
8/4 ohms: 0.05/0.05%
Noise level (A-wtd): -71.8 dB
Excess noise (with sine tone)
16-bit (EN16): 0.6 dB
Frequency response: 20 Hz to 20 kHz +0, -0.1 dB
* Speaker-impedance setup software-switch at "8-ohm" position. With switch set to "6-ohm," output was limited to about 35 watts (15.4 dBW) in all tests.

MULTICHANNEL PERFORMANCE, ANALOG INPUT
Reference input and output level is 200 mV; volume setting for reference output level was -3.5 dB.

Distortion (THD+N, 1 kHz, 8 ohms): 0.03%
Noise level (A-wtd.): -85.3
Frequency response: <10 Hz to 138 kHz +0, -3 dB

STEREO PERFORMANCE, DIGITAL INPUT
Reference level is -20 dBFS; all level trims at zero. Volume setting for reference level was -3.5.

Output at clipping (1 kHz, 8/4 ohms, both channels driven): 66/97 W* (18.2/19.9 dBW)*
Distortion at reference level: 0.04%
Linearity error (at -90 dBFS): 1.5 dB
Noise level (A-wtd): -76.4 dB
with 96-kHz/24-bit signals: -80.5 dB
Excess noise (with/without sine tone)
16-bit (EN16): 0.35/0.5 dB
quasi-20-bit (EN20): 12.5/10.1 dB
Noise modulation: 3.3 dB
Frequency response: 20 Hz to 20 kHz +0, -0.2 dB
with 96-kHz/24-bit signals: 20 Hz to 43 kHz +0 -3 dB
*Speaker-impedance setup software-switch at "8-ohm" position. With switch set to "6-ohm," output was limited to about 35 watts (15.4 dBW) in all tests.

BASS-MANAGEMENT PERFORMANCE
Measured results obtained with Dolby Digital test signals.

Subwoofer-output frequency response (crossover set to 80 Hz): 24 dB/octave above -6-dB rolloff point of 80 Hz
High-pass-filter frequency response (crossover set to 80 Hz): 12 dB/octave below -3-dB rolloff point of 80 Hz
Maximum unclipped subwoofer output (trim at 0): 6.4v
Subwoofer distortion (from 6-channel, 30-Hz, 0-dBFS signal; subwoofer trim set to 0): 0.04%
Crossover consistency: bass crossover frequency and slope were consistent for all sources and formats
Signal-format consistency: consistent for all applicable formats
Speaker size selection: all channels can be set to "small"
Speaker-distance compensation: available for all main channels.

呵呵,还是安桥够坚,但奇怪的是为什么那么多人说安桥推力不够,功率水份大
863真是太流了,但还是那么多达人推介863呢

希望主流型号都能更新
