個人音樂喜好很廣.Jazz, hip pop and trip pop (lounge/chill out music)
音效方面則喜歡,動態大,解析度高,細節多,清澈及明亮。雖然也喜歡甜美及暖味但我想只有管機辦得到。
目前考慮 CEC DA53, Musicland MD10 and Yulong DAC PRO with PCM1794. 不知各位大大推薦哪一個。如有其他選擇請介紹,預算在20000以下。謝謝

Q: Between optical and coaxial, which connection is going to give the better sound quality, and why?
A: " Better" is relative. In a harsh environment, optical may have advantages. By "harsh" I mean:
-Cable runs over 10ft
-Cable runs in close proximity to video and power cords emanating RF noise
In most cases, the above conditions would result in negligible impacts on the signal quality since the signal being transmitted (PCM or bitstream) is sampled at low frequencies (44-48KHz) and thus are more immune to noise impairments.
However, using optical cables can minimize the potential of the above mentioned problems and thus may help to reduce common mode noise. The only negative about using optical cables is the connection is not always as secure as a coax one, and can sometimes be compromised easily by moving components frequently. In addition, optical cables are usually more expensive than coax ones.
Bottom Line: Using optical cables for your digital connections may help minimize susceptibility of coupling RF noise into the line and reduce loss for long runs (10 feet or more). However, optical cables tend to be more costly and sensitive to abrupt external forces, which may potentially weaken the connection over time. In any event, either connection method should yield excellent and comparable results in most cases.
wayneker 寫:是的,我想聽聽看。但還是要先找一台DAC 來聽聽看。給點意見!
大陸做的如何?

wayneker 寫:聽說Citypulse DA2.03e 用 PCM1794.而且把USB2.0的訊號直接傳送到DAC晶片不用(USB to SPDIF -PC-link ).
我現在越來越糊塗了。我NB 只有toslink, USB2.0, firewire400 and firewire800, 沒有同軸。本想用toslink但現在才知道Toslink頻寬可能不夠。照理講,USB的頻寬應該比toslink高好幾倍.
所以應該找一台有USB的DAC? 不知道在哪看到, USB只能處理到16bit.
真是之越多煩越多。解救解救我吧.
wayneker 寫:我大部分的訊號是16bit/44.1 from my NB. 但我有一台SACD有toslink and coax. 所以你是說我根本不用擔心?
所以在upsampling/ oversampling, 根本沒差?
