对，你可以选更好的，这个便宜。当然关键还是要听感好，这个解码器我觉得性价比很高。

比如这种，插到电脑上还需要装驱动，是DSD解码器，当然其他格式也可以。

解码器再接功放或耳放什么的，现在哪还需要什么声卡，多个香炉多给鬼。

我自己在用PC+解码器，软件用FOOBAR，可以播SACD, DSD,ISO，效果比声卡好百倍！

我用功放听大箱，就是用这套方案，而且解码器还可以接数播，CD等音源。 本帖最后由 滚雪球 于 2018-11-15 13:37 编辑

USB接口的解码器不就是USB声卡嘛？

@vtec老师，先问个安~元气否？？
其实是又遇到要请教大师的疑难杂症啦
VOYAGEMPD最近更新了０.１１.０,实在是按捺不住升级的鸡动，再者又想在MACBOOK里安上去试试
没想到做好的U盘怎么地也是不认啊。。。OPTION啊C键啊等都按了，就是没法从U盘启动。。。
求指点~

不经意间VOYAGEMPD的最新版本0.11.0都已经默默更新了，坛里有哪位老师尝过鲜吗？

再给你加一个吧：这个应该是基于树莓派的最高DAC形态，核心芯片是ES9038Q2M,  厂家的说法是吊打7000 RMB 以下的任何DAC，（当然他没看过咱们中国国产的基于9038PRO的DAC）

Allo Katana DAC for Raspberry Pi

The story of the Katana ...

We asked ourselves how it's possible to bring true HIFI sound to the RPi. We wanted a price point that is accessible to everyone, while blowing away any DAC made by anyone under $1000. Let's see if we succeeded.

1. DAC IC
First we chose a very capable IC, the Ess9038q2m. This IC has excellent specs (theoretical THD+N at -120) and the analog stage (output) is left to the designer (more on analog stage below). One extra advantage of the Ess9038q2m is DOP. Of course, we used super caps and everything in audio path is film caps and thin film R.

2. Clocks
Any delta sigma IC is very sensitive to the clocks (jitter). We used the "ultra low jitter clocks from NDK NZ2520SDA. We also made sure that power was filtered by 2 LDOs in series along with a HF filter. Noise tested is in uV. Of course, we also used buffers (that also has its power filtered 3 times ...).

What we achieved is the lowest jitter ever (390fs).

3. Analog Stage
There are two kinds of analog stages: transfos and opamps. A lot of people swear by trans (with good reason), and others chose specific monolithic opamps. Still, the consensus is that transfos are better as far as sound quality (but very expensive and bulky), and that opamps are better as far as THD+N numbers. If opamps are used, the quality of the PSU (opamps need dual rail 15V) is very important.

Still, we felt that opamps CAN be better than transfos.

We concentrated a lot of efforts on this analog stage. You see, monolithic (integrated circuits) opamps suffer from the fact that not enough real estate is available on the silicon die. (Read an excellent article on this here)

So our choice was ultimately to build a discreet opamp (with IV stage we got 6 of them), while feeding it from a DC/DC convertor that has filters on input (+ LDO) and filters on output (+ LDOs), and of a course, a common mode choke (each rail has independent filtering) for a total noise that is lower than 1mV.

However, building an opamp is not a trivial task. What we did is partner with SparkosLabs_com and used his excellent design (thank you Andrew the wizard!). Read one review of those opamps here.

Each board is then hand-trimmed (individually) for DC offset (when board is warm to simulate conditions of a board that been running for at least 45 minutes), and then programmed for THD+N compensation.

So in essence, our Katana DAC is an excellent implementation of the Ess9038q2m in Master Mode (we are the first to do so), with a discreet stage made by 6 opamps running in class A amplification. THD+N numbers (1Khz, 0 dbfs, a weighted) at -112.75!!!

如果PChifi是指的以电脑为核心的Hifi系统的话，感觉没这么复杂吧。。。

PC+一个USB接口的DAC就可以了，后面再接功放/耳放这些就行。

其他基本弯路。

我也有PCM D100，被基于9038PRO的DAC吊打。现在已经打入冷宫了。

现阶段，9038pro或4497为核心的DAC，接出来再走个带前级的功放或前级+后级功放，再接啥都可以了。电脑没啥要求，就是存个文件就行，最方便还是SACD ISO.  

咳，我算馁门子行家，坛子里的波恩咖啡啊胡子啊永飞啊VTEC老师啥的这些才是行家呢，我都是跟着他们的指导在慢慢捣鼓玩儿

这个系列看上去完成度还是很高的，对应htpc的需求应该是绰绰有余

有点意思，换CPU不需要重涂导热硅脂，也就是说CPU上面有定制的模块？这个模块跟散热的热管是一体的？

４路泰坦都有点矿机的意思了啊
大家主要关注的还是如何在烧的路上走得更远更强，是不是音响不是最重要的，能有一台至强无敌无所不能的工作站是每个人发烧的诉求，多说说吧，我先搬个小板凳哈
