一般厂家的产品目录栏一般都是图片+介绍+specs 为多，
FM 产品首页不贴产品介绍，却来了这么一段：
Specifications are often misused, misunderstood, or utilized only to sell a product instead of indicating its actual performance capabilities. "Typical" specifications will not tell you much about the true value of a certain component. Only guaranteed minimum data as specified for all FM ACOUSTICS products, together with carefully controlled listening tests, will provide useful information.
Please observe these distinctions if you make comparisons with other product's data sheet.
As an example of the differences: almost all manufacturers quote rise time and slew rate either with no measurement details at all or at an unrealistic level of 1 W into 8 Ohm or so and are therefore able to quote impressive looking data. At FM ACOUSTICS, we quote rise time at full power -3 dB which is certainly much harder and honest than the good-looking but unrealistic 1 W rating of other manufacturers. Another example is power, where you will see absolutely stratospheric power ratings far away from any reality ('500W' units that have a 50W power supply, ghetto blasters rated at "800W" etc.). Even in 'high end' products - that are generally rated a bit more reasonably - actual differences of up to 300% have been experienced.
Compared with other amplifiers of similar power ratings, FM ACOUSTICS power amplifiers drive speakers effortlessly to higher levels. Actual SPL (Sound Pressure Level) differences of between 2 and 8 dB have been documented. This astounding distortion-free dynamic increase is one of the remarkable characteristics of FM ACOUSTICS' power amplifiers.
However, it must be realized that the traditionally used static measurements can never describe the actual capabilities of an FM ACOUSTICS when it is playing dynamic music signals. Bear in mind such differences when comparing data sheets.
FM米不起，但是由通篇对‘TPY specs’ 的痛扁来看，必有其自家自成一体的变态级 Know how，设计经验以及测试验证 |
