手上有个DECCA的唱头,型号应该是GOLD,针尖没了,且针杆歪斜。之前看到过台湾的烧友说过曾寄回给DECCA的J.WRIGHT先生维修保养,但不知如何联系,该怎样进行。请教坛上各位前辈,指教一下,不胜感激!

曾看到台湾一位大烧“聲音的無上幻覺”的博客(或个人网页,需翻墙):http://tgb.newcloudproxy.biz/bro ... WxlZS5odG1s&b=5
所以想最好还是寄回原厂恢复,才能听到比较真正的DECCA头声音。


关于这个唱头一些网上的介绍:
Other cartridges (both moving coil and moving magnet) have styli mounted on the long end of a thin tube (cantilever) which works like a lopsided "see-saw." The short end of the cantilever attaches to either a coil of wire or a magnet. At the fulcrum point, a flexible "rubbery" sleeve functions as a pivot, allowing the stylus/cantilever assembly to respond to the "wiggles" in the LP groove. Because the front section of the cantilever, which holds the stylus, is much longer than the rear section that is attached to the coil or magnet, a large movement of the stylus is transformed to a smaller movement at the coil or magnet, possibly causing cantilever-design cartridges to sound dynamically compressed and lacking in transient attack. London Decca's engineers advise that this problem with dynamics and transients is compounded by the cantilever's "rubbery" fulcrum point which tends to absorb a significant amount of the stylus-generated motion before it can reach the coil/magnet electrical generator assembly. Also, a smearing of the sound is said to occur, which many folks refer to as "cantilever haze."

The Super Gold has no long cantilever and no "rubbery" fulcrum point to absorb, dissipate and smear the vital musical energy. Instead, the stylus is attached directly to a magnetically active metal support just a few microns thick (armature) which passes through the center of the main generating coil positioned only about 1 millimeter above the stylus! The stylus motion is not inverted or "transformed" to a smaller value, as in long cantilever designs. Flowing from this immediate positive-direct scanning of the groove is a breathtaking, lifelike quality. The listener tends to feel that the performing artists are actually in the same room, with a startling, palpable presence.

The Super Gold uses line-contact, polished, grain-oriented diamond stylus similar to the Jubilee's, mated to less costly generator coils and housing. If you have never heard the $2875 London Decca Jubilee, you may well think the Super Gold is the world's best cartridge! Subjectively, it offers 90% of Jubilee's unrivaled musical realism.

Hifi World Review of London Decca Super Gold

"Sound was glorious, with superb image placement, powerful bass and detail retrieval of the highest order... the finest cartridge I've heard in my 40 years in the industry."

   你这个型号及它家的旗舰(参考)我都在用,是在台湾"小高音响"买的(此头的台湾代理),不知是傀佬做工的原因或者路上的野蛮邮寄,你这款唱头不是有这样问题就是有那样的问题,代理不厌其烦前后给我换了三次,直到我满意为止。后来还没忘向我介绍,这唱头除了声音好,还有一个最大的好处就是使用成本超低,如果你的唱头某一天用坏了,邮来给我们寄回原厂,花不了几百块钱,厂家负责维修。
   我不知你的唱头是通过什么渠道购买的,不妨跟他们联系一下试试,我敢肯定有惊喜,音响这方面,从我接触过的商家来说,天朝甚至于香港,都应该好好向台湾人学习。
