The increasing complexity of performance data makes it more and more difficult for the customer to recognize whether this is the real capacity output that actually arrives at the loudspeaker. Especially for low-budget amplifiers, dubious performance results are presented in order to boost the sale of products from Far East. Such deceivers are distributed almost exclusively through the Internet in large auction houses, where in many cases no staff with expertise can be found. There are numerous threads in Hi-Fi forums where performances and quality characteristics of power amplifiers are discussed, however, without reaching a clear conclusion. Different, usually not precisely defined measuring methods, frequently lead to comparing "apples with oranges". This page will provide clarity when it comes to the evaluation of power amplifiers.

Performance measurement results under exactly the same measurement conditions create the basis for comparability of power amplifiers. We plan to implement additional sound-influencing characteristics of amplifiers in the future. This includes the dampening factor which is frequently considered important, or others like amplitude response. We highly encourage critics and suggestions for further improvement.
