谢谢！

这两者怎么区分？我现在都没完全弄明白。

明白了。谢谢，看来是要买个壳了。

折腾了一晚，由于唱头盖子没有位移，超距多了1.2mm
最后还把唱针的宝石尖搞掉了。。。。。。
衰啊

谢谢楼上二位！

This new RIAA-MC-preamplifier symphono has been developed for highest
demands in analog music reproduction. The electronic design of the clearaudio
symphono is absolutely symmetrical. In order to achieve identical
amplification of each channel from the source to the other components the
symphono provides symmetrical output-terminals (XLR).
Another special feature of this preamplifier is the automatic adjustment to
any kind of connected MC cartridge load, which means, that the maximum
capability is always achieved without additional switches.
The symphono has no power-switch and should moreover be always
connected with mains in order to keep the ideal temperature for electronic
parts inside.

终于弄明白了，这款唱放是自适应阻抗的，所以没有匹配问题，应该是我的超距参数错误，长了1.2mm，造成了循迹错误，呵呵，可惜我的唱头又挂了！
