有一天,一位同事问我:一套Hi-Fi里选用哪一种牌子的电源滤波器比较好。我就告诉他:如不嫌贵,日本的古河PRO-168比较好,价格约2600元左右,如果要考虑经济一些的话,贵州产的“争先牌”W-4D也可以,价格在380元左右。 后来,我的这位同事在广州的荣生电器音响店里看到了一款北京清华大学精密仪器系制造工程研究所出的G＆WTW-02D电源滤波净化器,一问价格仅为338元一台。这位同事马上和店主人商量可否放下订金回去试用。店主人很热情,马上同意了。我的朋友拿回去试用后,感觉效果不错,特意向我推荐试用。因为他知道,我一直在用日本的古河168 One day, a colleague asked me: What kind of brand Hi-Fi filter power filter is better. I told him: If not too expensive, Japan’s Furukawa PRO-168 is better, the price is about 2600 yuan, if you want to consider some of the economy, Guizhou produced the “first card” W-4D can also be, the price at 380 yuan . Later, my colleague saw a G & WTW-02D power filter purifier from the Institute of Manufacturing Engineering, Tsinghua University, Beijing on the Rongsheng Electric Audio Store in Guangzhou. The price was only 338 yuan. The colleague immediately discussed with the shop owner can put down the deposit back to try. Owner is very enthusiastic, immediately agreed. My friend took it back to try it out, feeling good, specially recommended to me for a trial. Because he knows, I have been using Furukawa 168 in Japan
