德国tw-acusitc可说是近几年来迅速窜红起来的品牌,其最大特色就是那迷人碳纤维本体的黑胶唱盘,精细一丝不苟的德国工艺让许多黑胶迷乖乖掏钱买单,现在除了唱盘与唱臂外,tw-acusitc新推出了一台旗舰的唱头放大器Raven Phono RPS100.其采电源分离设计,对极为敏感的黑胶系统来说,解决了电源上会产生的干扰,不但为好声打下了基础,还避免了许多问题.
RPS100采用两极放大与主动式EQ线路,其中使用了真空管放大,包括两只12AX7及两只6922,动差式的电源供应采用了高品质的MKP电容,为了确保让噪音达到最小,使用了非常精密稳定的DC直流供应(DC heater supply),在动圈极(Moving Coil stage)部份,使用了高品质的输入变压器.
Raven Phono RPS 100拥有三组用家可以自行设定参数的输入,前面板的按纽与萤幕可以非常方便的进行切换与设定,包括MM或是MC、阻抗匹配、EQ曲线,共有RIAA, EMI, DECCA, MERCURY, COLUMBIA等五种,还有正反相设定、萤幕显示开关等等.
