这次我超级满意，剩下的就要靠咸菜微调了。

我打算上fe的cerabase配合signature架子。

这个架子实在是太好了。。。

是Polyfusion Audio Model 800？ 我记得此机价位不高的啊， 差不多是1万2千上下吧？

布版的转盘升级到怀念7了？

呵呵，十来万的解码尽管可以去跟这个Model800过过招，他功力可深厚着呢：）

某些方面肯定是不错的
就像当初我说Wadia 7的中频肯定比P70好
但是你问问Bruce P70其它方面怎么样

开心发烧鼠

恭喜一下沈兄。。。

摆位不变，无论器材怎么换，音场永远是出不来的。

如果你想说我是傻子尽管说，但好声音是金钱不一定能买来的。

对的， 我是准备换摆位， 慢慢来。 不过p70硬生生把音场拉宽拉深拉高， 这点我非常吃惊。。。。
