基本都是HI-END级别啊
看来Z7的确潜力、挖掘空间很大，还有以前对煲机持不以为然观点导致把Z ...
确实~~而且还有一点，某种意义上Z7是纵向立体声场的“HD800”，HD800夸耀的就是它的声场，但主要是横向大声场，但在立体坐标轴声场上~~旗舰动圈里面，Z7的存在感是最强的，简单的说就是立体坐标轴Z轴方向的声场，具体说就是头顶位置，如果说现场的话，那就是穹顶了~~~还有就是残响的存在感极强~~~

看到你在别的论坛寻找DSD的DAC，看看AK4490EQ是直接的吗？http://audio.teac.com/product/ud-503/，其中对AK4490介绍时提到Not only is native playback with direct processing of 11.2MHz DSD signals possible？

是的~~不过偶现在这只平衡放真的有点买彩票的意思————绝版品，没得试听。。。
Four types of PCM digital filter and two types of DSD filterIn addition to four types of PCM digital filters and an OFF mode, the unit has two types of DSD digital filters, so you can choose the best filter for the input file format and type of music. You can enjoy the subtle sound nuances of different filters without needing to connect different USB DACs.
PCM Filters
FIR SHARP:An FIR filter with a steep roll-off sharply cuts signals outside the audio band.
FIR SLOW:An FIR filter with a slow roll-off gently cuts signals outside the audio band.
SDLY SHARP:A short delay filter with a steep roll-off sharply cuts signals outside the audio band.
SDLY SLOW:A short delay filter with a slow roll-off gently cuts signals outside the audio band.
DSD Filters
CUTOFF50kHz
150kHz
NOTE: When receiving signals at 352.8 kHz or 384 kHz, the digital filter will be disabled during playback regardless of this setting.
好像是提到了PCM/DSD两种滤波器啊？

没用～～因为信号是转过一次了的～～～现在的芯片都是多了个中间过程～～所以实际意义上是芯片级软解
现在实现ＤＳＤ硬解的主要方案还是电阻网络，就是Ｒ２Ｒ，还有一个特殊的就是ＳＯＮＹ Ｚ１ＥＳ上的独立ＤＳＤ解码模块

哦，看来还是SACD推广不利啊
不过索尼自己也用ES9018解DSD……，发挥不了自己制定的1bit解码优势

你是说PHA3么~~~问题是小东西肯定要使用集成度高的芯片啊~~~SACD本来就是半死不活~~除非玩HI-END的那些转盘~~~而且DSD本来就是SACD专利到末期的数字解决方案（也没有版权）~~而且。。。世界上最早的SACD抓轨就是用的初代PS3，，而传输是HYDRAZ这些数字界面使用的IS2传输啊~~
说句实话，建议lz去听听hugo吧，你列的那些会被甩开一条街，加点钱也值了
