NAS 接駁 DAC 加唔加 DDC 好？

師兄，個 source 唔得，乜 DDC 都救唔返。你的諗法同你的要求在南轅北轍呢。你想行個路係呢到大把師兄都 ...

即係咁，當有人問買邊隻 CD 機好聲時，你話砌部電腦會樣樣都好 D，咁我唔係話你唔啱，不過買底板上機殼裝 OS (仲要係 command based 既 Linux) 摸 setup 然後再返大陸訂 LPS，並不是每個人都會選既路，呢 D 玩意可能我個仔會啱玩多 D！

至於個 source 唔得，乜 DDC 都救唔返呢句，我有點保留，兩條路唔同，會有不同既問題，用從新開始去學習，搜購，等/催貨和落手落腳既時間去接份 freelance job, 可能已經夠錢買部 Weiss INT204 了，係咪會一定衰聲？  I am not so sure.

其實無興趣 DIY 完全無問題，各人喜好不同。祝師兄早日攪掂，輕鬆聽音樂。

我也弄不清楚，我還以為我在頂樓提出的問題是很明確的，但卻和突然 DIY 拉上了關係！

現在看來現重新開 thread 問 DDC，和寫明不考慮 MDP 了！

Ching,

From the system block diagram in your first post, it is quite clear that using USB input will go thru the XMOS chip. As you know, using DDC, it means you will use another chip (may be XMOS may be other brand) that does similar thing as the USB part in YuLong just there is one more step in converting signal to SPDIF vice versa.

Whether this will be better sound or not, it's very personal. IMO, if just play 44.1, using SPDIF not 100% loss compare to using USB directly, given the above audio experience that I have, I would say, if you find one DDC which in your point of view sounds exactly what you want, then go and buy it.

Further elaborate what my audio experience about SPDIF is that, it may sounds more analog and musical (for 44.1 only). If you gonna play high-res / DSD, sure go for USB.

Right now I am using DAP as digital transport, using a 3.5mm to RCA coaxial cable to connect with D200.  Playing hi-res PCM file is not a problem, easy and straight forward.  The only drawback is unable to play DSD files through SPDIF connections.  

I have not heard them at a fair AB compare, so I can't be sure whether USB will sound better.  

I do not expect the XMOS will outperform the ES9016 at chipset level, but it is meaningless to compare two chips solution like that, as execution is a big variable. By observation, audiophile DAC will have better (more experience) SPDIF execution then USB solutions, I'll be surprised if Yulong is the other way round.  Yulong is experienced in Sabra chipset, his previous product DA8 using ES9018 was a big hit in US HeadFi, too bad Hong Kong tends to under rated PRC products and the product got zero coverage here.

Yes, finding the right DDC solution is the key, that's why I started this thread here, and I hope I can explore this option before turn to other solution.

You are damn right! YuLong should get more spotlight.

Again, I think you shall go out and try some DDC to find one you like, probably you can bring your NAS and DAC (both are not too large) and try to plug them and try in shop if they allow.

Just go try in the showrooms/shops. The int204 (by 方浪?) or ifi (by Avantgarde) products shall be good choice (I have not tried).

c hing, in fact, the main purpose of DDC is by-passing the lousy USB input component in some DACs, with the help of coaxial input.  It re-clocks and converts the usb signal to spdif format.   

So please don't expect DDC will making up, nor polishing a lot the original signal.

Great, this is the right channel that I am looking forward to.

I am interested in the ifi products as well, so you have used three ifi products in the chain, care to share with us more detail?  what is the total cost for the three at retail?  Can I get good result from using ifi power along?

Schiit has announced a new product product called Wyrd, it share some similarity with ifi proudcts, I don't have any updated beyond reports from T.H.E. Show,  if you have experienced with ifi product, maybe you have more insight on this one and can share with us.

Wyrd cleans up USB power with an ultra-low-noise linear power supply (no switchers here) and repeats it with a precision crystal oscillator-controlled interface. We're not going to make any claims about sonics, but it'll definitely stop USB noise and power problems in their tracks. Some people say Wyrd makes everything sound better. We don't know how it can possibly do so, so we're going to stay Swiss on the subject. Wyrd will ship in June for $99.
