I'm not sure if you meant to say this.
If you can use English, please use English.
1. RS250 is network streamer and DAC. You can use DAC in RS250 if you want. If you don't want, use USB OUT.
2. RS250 is capable of full decoding. However, if an external DAC is used, it cannot be fully decoded and sent to an external DAC according to MQA rules.
3. I don't understand Chinese, sorry.
想請問一下RS250 係純steamer 配搭本身沒有MQA support 嘅其他牌子DAC使用都可以直接full decode Level 3 MQA? 定係好似roon咁淨係解到Level 2至24bits 96KHz?
