咁係 Fully Balanced 定 Differential Balanced ?

如果無記錯DAC行真正Balance係要每個channel用獨立一粒DAC

先了解咩係Fully Balance，你就會明白，無十個八個係玩唔到Fully Balance，有XLR端子唔等同部機係Fully B ...

又學到野… 多謝分享!
以下2部是同廠的DAC，上圖是全平衡，另一部只RCA輸出

呢部好似$4XXX，如果係咁都算幾抵玩喎。

好多 DAC chip 直出 balanced，用兩粒多數玩 mono block 或并聯，唔關 balanced 事。
全平衡聲音 =兩聲音分開解碼 (即是以兩個單聲道解碼，需要用到兩粒Mono DAC) + 兩聲音分開輸出設計 (兩個平衡單聲道輸出，用上XLR傳輸)
要駛amp的話還要分開連接到兩個一模一樣的Amp。

What will be the advantages for mono block 或并聯 in DAC?
Wilmer, can you explain a bit that if a DAC has both RCA (single-ended) and XLR (real balanced) output, is it always true that XLR is better in all aspects? More complicated situation is that if the we connect a DAC to a pre-amp through XLR but connect a pre-amp to power amp through RCA, can we still enjoy the benefits of "fully balance"?

點解咁樣接粒 DAC chip，如果唔講解電路，等如講返廠家 d 咩增加動態呀、細節呀。。。果 d SALES TALK，但係呢度唔係 DIY 網、大家又冇電子底，講左等如白講。
講明“FULL”、“FULLY”，咁你話點先係正確玩法呢？
你鐘意咪講囉, 我實捧你場喎...
