Printed words cannot do justice to these products as they cannot transmit the exhilarating experience of recreating musical events with an FM ACOUSTICS.
The information on these pages, therefore, is of general nature to allow some insight in the philosophy, the technology, applications and results. But only when actually hearing an FM ACOUSTICS will you capture the full meaning of all these words.
Specifications are often misused, misunderstood, or utilized only to sell a product instead of indicating its actual performance capabilities. "Typical" specifications are unable to advise 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.
Just one example of the differences: most manufacturers quote rise time and slew rate either with no measurement details at all or at an unrealistic level of 1 W into an 8 Ohm load 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 impressive-looking but very unrealistic rating at 1W.
Another example is power, where you will see absolutely stratospheric power ratings far away from any reality ('500W' units that have a 100W power supply, ghetto blasters rated at "800W" etc.). Even in 'high end' products actual differences of up to 300% have been experienced.
Compared with other amplifiers of similar power ratings, an FM ACOUSTICS amplifiers drives speakers to higher levels - and effortlessly so. Actual SPL (Sound Pressure Level) differences of between 2 dB and 8 dB have been documented. This astounding distortion-free dynamic increase is one of the exceptional characteristics of FM ACOUSTICS' amplifiers. The result is that an FM ACOUSTICS amplifier that is less powerful on the spec sheet will provide better dynamics than other amplifiers.
It must be realized that the traditionally used static measurements cannot at all describe the actual capabilities of an FM ACOUSTICS when it is playing dynamic music signals.
Many more differences in characteristics and performance are not visible in spec sheets. Bear this in mind when comparing specifications as such matters make all the difference in actual reproduction accuracy.
