“凯风一号”(KF-1)为福建凯风电子设备厂于1999年研制的立体声高保真音频功率放大器。在设计上力求简洁、用料至上的原则,独特的电路设计使该机音色清亮、醇厚、具有独特韵味,很有人情味。‘凯风一号”一经推出,其优美的音色、精湛的工艺便受到全国广大发烧友的青睐。设计人员并未停止对“凯风一号”产品的研究,而是征求众多发烧友意见,进一步完善电路及机器工艺,做了如下改进:
“Kai Feng One” (KF-1) for Fujian Kai Feng Electronic Equipment Factory in 1999 developed a stereo high-fidelity audio power amplifier. In the design of the principle of simplicity, material-oriented, unique circuit design to make the machine sound clear, mellow, with a unique charm, very humane. After the launch of ’Kai Fung One,’ its beautiful sound and superb craftsmanship are favored by the enthusiasts in the country.Designers did not stop the research on the “Kai Feng One” product, but solicited opinions from many enthusiasts to further improve Circuit and machine technology, made the following improvements:
