Upgrading the preamp really boils down to 3 key areas: 升级前置真正归结为三个主要领域:
1) power supplies 1)电源 2) component selection 2)组件选择 3) grounding issues 3)接地问题
These are not really clearly seperate issues as there is some crossover between the subjects and also involve external psu's of various designs. 这些都不是真正独立的问题显然是有一些与主题和外部电源还涉及不同设计的交叉。 However the gains that can be gotten from these areas are all large and can transform a humble little 32.5 into a total giant killer of a preamp that can stomp naims finest products. 不过 , 可以从这些地区都是不义之财大 , 能够转化成共1前置 , 可以单块naims最好的产品巨人杀手32.5个谦虚一点。
POWER SUPPLIES to a large extent boil down to the quality of the regulator used and monolithic regs such as the lm317 are NOT up to scratch. 电源供应系统 , 在很大程度上归结如lm317对所使用的调节器和单片regs质量不达到标准。 See PSU page for more on thisl 查看更多关于电源页thisl COMPONENTSs. COMPONENTSs。 The quality of the capacitors is by far the dominant factor in preamps and to cut a long story short, the electrolytics (ie all the caps in a standard Naimpreamp) should be replaced, ultimately with film caps. 该电容器质量是迄今为止在前置放大器的主导因素 , 减少长话短说,在电解电容(即在所有的标准Naimpreamp帽)应改为最终与电影帽。 Resistors and transistors have only a minor affect on the sound. 电阻器和晶体管对声音只是一个很小的影响。 EARTHING is nice as it is cheap to do and simple and reaps big rewards in terms of musical accessibility. 接地是好的 , 因为它是便宜和简单的做和普及方面的音乐方面获得巨大的回报。 Everything becomes bigger, bolder more realistic and textured. 一切都变得更大,更大胆更现实和质感。
