CARYCAD-300SEI自推出至今已逾十多年历史,每年都被美国发烧天书《Stereophile》评为年度A级产品,可说是Cary产品中最具典范之一。而时至今日,Cary厂方还在不停地对CAD-300SEI作出改良,令其力臻完美。光是300B真空管也更换过不小牌子(包括CETRON、KR、WESTERN ELECTRIC西电……)功率也由原来的11瓦×2提升到现在的15瓦×2。一台胆机好声与否,关键在于其所运用的线路及重要零部件(特别是输入输出变压器的绕制),CAD-300SEI就是运用了最简单最直接的单端放大线路及全机使用发烧补品零件(Kimber电容、Dala电阻、WBT插座……),机内所有连线都使用Kimber银线全人手搭棚焊制。而置于机身后方用铁壳屏蔽的两个输出变压器均是厂方特别设计的,其空气间隙容量超大(比正常大一倍)采用高质漆包线及固蜡方法绕制,故此它的输出效率极高。电源滤波采用两支容量高达1200MFD的优质滤波电容(这可能是CAD-300SEI可达15瓦×2的秘密所在)。一般胆机只特出中频部分的声间而Cary CAD-300SEI在中高低各频段都很均匀(音色饱满、 华美、艳丽之余有不食人间烟火之感。
1.使用单端式放大线路,全机使用多种发烧补品零件(Kimber KAP电容、Dala电阻、SCR苏伦电容等),全人手搭棚焊制
2.输出变压器设计其空气间隙容量超大(比正常大一倍)采用高质漆包线及固腊方法绕制,故此它的输出效率高达15W*2
3.使用胆管:6SN7*3(前置及驱动)、300B*2(强放)
4.特有耳机输出,可通过开关选择耳机输出或喇叭输出
5.美国发烧天书《Stereophile》高度评价,连续多年荣获年度A级产品
