请教数播对音质有多大提升？

boxerlc

一般的系统，升级三大件回报会比较高。在不怎么折腾的情况下，使用一体机，并用USB连接，是最简便、声价比最高的方式。如果以后想折腾，三大件到达一定档次之后再关注音源方面，音源素质好了，声音的效果会锦上添花。不过数播性能参差不齐，不一定会有明显的提升，据要再具体研究。现阶段建议钱先留着，看后期的需求再花。成本较低的提升音质的办法有一个，就是装个HQPlayer，试试升频的效果。HQPlayer是提升原始信息质量的方式，和数播带来的提升不同。假如用了好的数播，同轴性能极强，可以带飞你的解码，低频质量会提升、结像清晰度和定位也会变好，提升程度取决与数播的强度和后端的潜力。

用耳朵收货

用了几年声韵MX+解码的USB界面接PC听歌

如果你的设备和Roon是USB连接，那就直接在HQPlayer里面打开网络控制，同时把设备设为默认播放设备。之后在Roon里扫描并添加本机的HQPlayer就好了。
如果你是Roon通过网络推送到设备，想要用HQPlayer的话也可以，不过在设备前需要加装一台树梅派做NAA适配器。

HQPlayer Setup

User Guide > Audio > HQPlayer

Roon can stream directly to HQPlayer, whether both applications are running on the same machine or if they're on different machines on your network.

Note: HQPlayer 3.12.0 or higher is required.

Setting Up Roon And HQPlayer

To setup Roon to output to HQPlayer follow these steps:

Step 1: In order to connect to HQPlayer using any address other than localhost or 127.0.0.1, you must enable the "Allow control from network" feature in HQPlayer. This is the globe icon on the far right hand side of the HQPlayer toolbar:

MacWindows
               

Step 2: In Roon, go to Settings/Setup/HQPlayer and click "Add HQPlayer".

Step 3: Enter the network address where HQPlayer is running:

• If HQPlayer is running on the same computer as your Roon Core, leave the default localhost value, then press Add
• If HQPlayer is running on your network but on a different computer, enter the local IP address of that computer, then press Add.
  

Note: You can find out your IP address by following the instructions here -- just make sure to use your local IP address, as opposed to your external/public IP address. The local address will most commonly look like 10.x.x.x, or 192.168.x.x.

• Finally, choose HQPlayer from your Zones menu
  

Notes for Roon/HQPlayer

When controlling HQPlayer from Roon, use the transport controls within Roon. If Roon detects that you've manipulated transport controls from HQPlayer, it will stop the music and release control of HQPlayer.

HQPlayer has multiple options of displaying the play time, “time”, “remain” and “total remain”. You will want to select the first option of "time" in HQPlayer for the playback bar to properly progress in Roon.

An HQPlayer instance can only be controlled by one external piece of software at a time. This is an HQPlayer limitation. If you attempt to initiate control from another piece of software, Roon will lose control of HQPlayer.

HQPlayer filter settings can be adjusted from within HQPlayer. This works best if you first press the "stop" button in HQPlayer, then make the adjustments you want, then proceed in using Roon.

If you're using a device in HQPlayer, make sure that the device is disabled in Roon's audio settings. Both Roon and HQPlayer expect to have exclusive access to the device, and they might conflict if you configure both at the same time.

谢谢指点。。那我还得加个树梅派做NAA适配器

低成本的方式就是买一个树莓派，外壳和SD卡，下载一个dietpi镜像或者raspbian镜像，之后安装naa就好。
进阶的方式就是买Allo家的USBridge或者USBridge Signature。隔离和电源都经过优化。
