看了心寒 我本来去买个5.1声道的名机
看来还是算了
看了,过过隐.
好贴，学习了。

当然！
有些名机工艺似乎也比我好不到哪里去阿
谢谢提供资料

好不到哪去？是什么好！！！！？？？？
好不容易全部看完了，结论只有一个，跳线好比桥，绕过河和上桥，大家自己选择吧！跳线没有什么不好的，非常合理啊！本人做机，跳线就是要使用的。关于焊点和飞线和铜箔的见解，那个简直就神学，不要迷信！
名机 ...

神是可以吹出来的，呻吟可没法吹！
能创造的是神，膜拜的是信徒！！大家好好DIY吧。

外国名机反映出一个PCB设计理念：电路图的电气性能优先！材料够用就好！工作状态调试到位！拥有雄厚实力的厂家不会连做个PCB板的水平都赶不上业余烧友的水平吧？是对放大器内涵的理解和设计理念及东西方文化习惯的差异表现。一句话：用黄金做的坦克价格最昂贵，但是绝对不是廉价钢铁坦克的对手！
楼主应该是专业修理功放的吧？
以前我也是修理功放的，见过很多名器！
什么时候Jungson、Shengya也成名机了？不解。。。。
参观。。。。
我也来凑下热闹
都是些好东东丫!
不管用啥材料，好声技术才算高！
好不容易看完了,很好!很好!
大开眼界
