DA924 input只有AES/EBU 跟同軸
您如果用mac mini要接的話有以下幾種方法
一千以下:
用Mac Mini的光纖轉同軸 (700元解決，PCHome有賣)，音質不知
5千以下:
USB轉同軸DDC方案(要有Mac driver):
M2Teck HiFace
M2Teck HiFace EVO
阿仁做的XMOS USB DDC
6萬以下:
Berkeley Audio Design Alpha USB 非同步介面

新手對這方面不了解請包涵。請教如dac使用Lavry DA924 有辦法接上 mac mini或 Lavry DA924要連接何種訊源?

La Rosita的無線方案真的是比USB的solution要容易出好聲，USB要好聽要花很多心力
我看國外無線DAC的討論是Rostia beta的音質比Mircromega WM10要更令人印象深刻

引述 Rosita 老闆的說法如下
In fact many equipment data sheet show that a lot of machines and other USB DAC type can 24/192 reproduce through an USB connection, Ethernet or Firewire. See advertising ....
WARNING! let us not take for donkeys as the "jitter" ultra low which was supposed to guarantees the quality of a DAC.....
About you to connect your computer to a HD DAC you MUST KEEP in mind the principle that "digital noise floor of your computer" can't be over passed.
24bit/96kHz is a dynamic of 146 dB or a noise level of -146dB !
Computers are unable to, (far from it), work with a lower digital noise that 90dB. that's what looking for people who use measuring instruments based on computer motherboards. The motherboard can not do it because of the noisy power supplies necessary to computers. (High Frequency power supply)
The absolute record is close to (-140dB) and is achieved by using oscilloscopes motherboards specially dedicated. (Eg: LeCroy) We are equipped.
As also distributors of Audiomatica CLIO measurement system, we face the problem regularly. http://www.audiomatica.com/europe.htm
A link RJ45, USB 2.0, FireWire put unfortunately the computer and the DAC at the same ground potential (bonding modes common) and even though the guts of the machine could do digital audio only TRUE WIRELESS happen to reproduce levels of "digital noise" so low because the connection has no physical contact with the computer. It'easy to make a 24bit 192 kHz USB DAC, look..... http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=300591940169&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
We remain very committed to wireless because it is in our opinion, the ONLY current solution to meet at least the -96 dB of the CD! what is already an achievement ...
to the wise ....
friendly yours Dan Bellity

我不知La Rosita的無線方案傳輸方式跟SQUEEZEXBOX的WIFI傳輸有無不同
以前用TOUCH，只要使用微波爐，WIFI就會被中斷，導致BUFFER傳輸不及音樂播放中斷
，有時也會小LGA但不常出現(我也不知是電腦還是軟體問題哪的問題)，用WIFI感覺蠻容易受干擾的
後來我就不用TOUCH當轉盤了，直接買只有USB輸入的QB9，，加個獨立供電USB HUB(這個影響最大好很多)
不同的電腦播放軟體聲音，聲音還是聽的出有些不同，PC端還是有些變數的
但以中階來說，差距還不算天差地遠，不過QB9只有USB輸入的設計我覺得蠻"賤"的
因為讓你完全沒有辦法比較不同數位輸入的差別。
