- #16 [beeos], 19-09-29 11:53我用 Pi + reclocker I2S 出
- #15 [Ck2007], 19-08-31 08:39Iso regen 當然好！
價格有點貴、本身套系統沒有明顯噪音；爬文揾到ifi idefender3.0, 幾百蚊可試下.

- #12 [wklie], 19-07-23 12:52#11: Native DSD processing needs to be disabled, especially for low end CPU.
It refers to a completely different thing from "native DSD" people normally associate with USB DAC. This option has no relation to DoP vs native DSD.

- #10 [Ck2007], 19-07-23 00:51Nuc j3455 未開s-d modular只轉dsd256時只得0.7x, 播幾十秒就會卡住繼繼續續.
3x已開s-d modular已換另一部腦；我無用hqplayer, 只係部r2r dac隨便揀model試下.
- #9 [wklie], 19-07-23 00:073x is a good enough processing speed if you are not using HQPlayer. But the jump from 0.7x to 3x is more than I expected for enabling Parallelize Sigma Delta Modulator. Is this the same J3455 NUC with the same Roon+HQPlayer configuration / signal path?
Normally people who use HQPlayer rely on HQPlayer to upsample instead of Roon. Either you use Roon to upsample without involving HQPlayer, or let Roon send bitperfect audio to HQPlayer to upsample.

- #6 [cashotline], 19-07-20 09:56usb消耗大量cpu資源並非理想輸入方式，師兄可以考慮FireWire會有驚喜
- #5 [ck2007], 19-07-20 09:21試咗一排, 本來想行Linux Core 都唔可以直出USB行Native DSD! 爬文及請教其他師兄, Linux play native DSD 都要更新ALSA driver包括Roon Rock.
Roon 直出USB DAC都係Win10行ASIO driver係最簡單.
自己用緊部DIY Soekris DAM1021行Combo384 Amanero USB interface 所有format Upsampling 去 DSD256 輸出DAC正常. 目前用一部舊NUC(J3455cpu)試, 只做upsampling未加Filter, processing power 已到0.7x 下一部考慮電腦Hardware. - #4 [chariot], 19-07-05 23:23要睇你部DAC食邊種format最好聲。
Roon 可以軟解MQA同升頻，轉DSD。

- #2 [chariot], 19-07-05 20:15先講你用乜DAC.
- #1 [Ck2007], 19-07-05 20:08請教用緊Roon師兄；我考慮用Roon主要係音源提升、但唔知有無理解錯！
因睇國仁介紹Roon可以播放時解mqa和轉dsd輸出DAC.
買PC装Roon server用usb接我部dac可直解dsd就可以有大音質提升？
包括mqa audio file?
Thanks - 返回 ...
Roon
同一個種wav file, nas＞Roon(轉DSD)＞poly+mojo比直接由poly內sd card+mojo出好！連貫性、密度、純正. 這些帶來提升了音樂感聽得更投入.
所以非常推薦朋友用Roon
