如只RCA出聲，咁怎樣接上DAC？

RCA是Analogue傳輸，已經是Analogue就冇需要及冇可能駁去DAC了。

在推出SACD時，因商業利益考慮，SACD player的DSD信号是被限制只能通過HDMI或proprietary cable傳輸，所以經coaxial 或optical fiber是不能播放SACD的DSD的。聽聞有人改机改到coaxial或optical fiber可以播DSD。

SACD players do not output DSD signal to coaxial.

Lumin players (if playing DSD file from network, or upsample CD to DSD) can output DSD signal to SPDIF output via DoP format.  However, even if a DAC supports DSD over USB, only some of them support DoP over coaxial.

怎樣知dac有dop？我正用MF dac M1，ud5005聽sacd only經同軸去M1落Amp有聲，是什麽意思？ ...

Your SACD player could be converting DSD to PCM (probably 88.2kHz) and sending it to coaxial.  Or it can be reading the CD-layer of the SACD disc and therefore sending 16-bit 44.1kHz.

I'm not familiar with your DAC, but typically a DAC has LED or front panel to indicate the PCM sample rate or DSD it's receiving.
