要隻DDC同clock都support SD64, DSD128 + DXD clock rates先得

In this way, you can fully utilize the features of Mytek with lowest jitter and interference.

會唔會將 SACD ISO 轉為 AIFF 去解決呢
咁玩已經唔係玩DSD，建議你用notebook直入Mytek聽DSD同經clock聽PCM，聽下有乜分別。
Mytek最大嘅賣點係可解DSD，唔玩DSD有啲晒咗部Mytek，但資源係一個問題，
一係自己用部PS3厚機自己rip，一係去買(http://bluecoastrecords.com/formats/dsd)。

The problem is Mytek usb input does not support external clock in signal {:1_247:}
so I said use external clock in my system is so 雞勒{:1_255:}

MACBOOK AIR > USB > M2TECH > COAXIAL > DAC > RCA > 前級 > RCA > 後級
M2TECH 另外再駁多條線去 原子鐘
我咁樣駁法可以解決呢個問題 {:1_332:}

可以，玩PCM上到192khz都無問題
只係M2tech hiface唔support DSD64，DSD128，
當播DSD時可以用usb直入Mytek

都可以好似丁蟹兄咁玩，不過會唔會比用SBT加Sotm入Mytek加external clock好就要試下

我買呢部二手
個位師兄就係 加Sotm入Mytek加external clock好
我覺得效果OK

下面嘅文章就係一直我好confuse嘅問題，到底加一個比Mytek internal clock嘅更precise 嘅external clock真係會比用usb入Mytek行async好?

It depends. A good SPDIF interface can be better than a poor USB audio interface. A decent Asynchronous USB interface should be superior compared with the best SPDIF interfaces.
The SPDIF doesn't have a clock line, the clock has to be recovered from the data. Some devices are very successful in doing it, but the question is why lose the clock at first place. Jitter specifications for SPDIF interfaces are sometimes telling you half of the story. Jitter occurs at the transmitting and the receiving end of the cable. A USB to SPDIF interface may have a very low jitter on the output BNC connector, but you need to take into account the jitter caused by the cable, and the jitter of the SPDIF input of the DAC. Of course you can experiment with cables and you can try to find devices that work together well over a SPDIF connection.
SPDIF is limited to 192kHHz sampling rate and 20 (some say 24) bit resolution. TOSLINK or optical SPDIF specification is limited to 96 kHz, some devices can do 192khz.
Asynchronous USB is a technologically more advanced way of moving audio streams. Asynchronous means that the DAC is controlling the computer and it can ask for data when it needs them. This makes it possible for the DAC to use very precise clocks. If the computer is ahead or behind, or as usually happens all over the place with its clocks, the DAC can control it and put some order in the delivery of data. True asynchronous USB interfaces have ZERO jitter. In plain language they don't cause errors in the timing of the audio stream.
DACS that use asynchronous interfaces don't have to worry about correcting the interface timing. DACs that use SPDIF have to be very good at reducing jitter. Asynchronous USB is a smart way of connecting audio devices.
It is easier for asynchronous interfaces to be bit-perfect - they utilize two-way communication with the computer. If there is an error, the DAC can request the broken data package again and again until it gets it right. This is impossible with SPDIF.
Asynchronous USB interfaces are not sensitive to the quality of the USB cable. You don't have to go through trials and errors to match the USB output of the computer with the cable and the asynchronous USB input of the DAC.
Finally USB interfaces are not limited to 24bit/192 kHz. There are several devices that can do 32bit/384 kHz and beyond. Is this practical? Yes, if you want to do advanced upsampling, DSP processing like the best recording studios, digital crossovers or simply to listen to the 2L DXD studio master files in their native format.
