(CD9SE内部赏析)
这台CD9SE在之前的2020年度推荐器材发文中被选中就是因为厂家把该花的钱都花在了刀刃上,从整体到细节都很用心。CD机要出好声,关键在哪几方面?
*扎实的电源储备(使用两只变压器加滤波电容阵)
*稳定的转盘机构(采用几乎绝迹的飞利浦pro2转盘)
*重视模拟信号放大(采用4支6H30超级管做放大)
*强大的D/A转换性能(24Bit DAC双单声道线路架构:采用四路24bit数模转换芯片以单声道模式运行,配合双主时钟系统工作,一只处理44.1kHz/88.2kHz/176.4kHz取样率的数字信号,另一只处理48kHz/96kHz/192kHz取样率的数字信号,同时还进行时基校正,并提供升频功能。)
*与时俱进的数播解决方案(USB线连接笔记本轻松组建高素质数播系统)
此机适宜人群
手头CD收藏一大把,又想兼顾一下本地数字文件播放的烧友。小毛体验下来,既方便又有素质。同时,如果您想在系统里加入胆环节,让系统增添些模拟味的也相当适合。因为系统里加胆CD的排异风险比加胆前级低得多。
