优秀的放大器极少对它所放大的声音产生甚至是很细微的改变。这种被称为没有“个性”或是音色透明的放大器,不会单独强调中频或低频或高频,也不会扭曲声场和减小动态的表现;同时它能够驱动大部分扬声器,而且不会改变音箱本身的音质特点;同时,放大器在工作时不会在电压及电流驱动方面有局限性。上述这些特点已成为几十年来Hi-end放大器追求的共同目标。但要做到完全满足这些要求无疑是相当困难的。曾经有许多的音响厂家,包括本文介绍的主角音乐传真都曾利用“渲染”这一手段来对声音进行“美化”。
An excellent amplifier rarely makes even minute changes to the sound it amplifies. This amplifier, known as “personalityless” or timbre, does not emphasize IF or LF or HF alone, nor does it distort the sound field and reduce dynamic performance; it also drives most loudspeakers and does not Change the sound quality of the speaker itself; the same time, the amplifier will not work in the voltage and current drive limitations. These features have been the common goal pursued by Hi-end amplifiers for decades. However, it is undoubtedly quite difficult to meet these requirements completely. There have been many audio manufacturers, including the lead music faxes described in this article, that used “rendering” to “beautify” sound.
