dac25b 與 dac25a 看背版,差異在25b多了ipon輸入端,不知道還有沒有其他不同的地方?
第二篇貼成25a了,電腦顯示xmos usb晶片,和25a的tensor晶片不同
樓上的優秀，知道我在說啥.......差異我整理一下
各代主要更改USB接收晶片部分
DAC25A 將USB界面由USB1.1提升到USB2.0
DAC25B 加入XMOS模組，其中包括增加iPod輸入
USB接收晶片部分差異：
同軸光纖DA晶片 數位接收晶片
升頻晶片 USB晶片 DAC25 BB PCM1792 Cirrus logic CS8416 BB SRC4192 BB PCM2704 (48k/16bit) DAC25A BB PCM1792 Cirrus logic CS8416 BB SRC4192 TENOR TE7022L (96k/24bit) DAC25B BB PCM1792 Cirrus logic CS8416 BB SRC4192 XMOS (192k/24bit)

Ｏｎｉｘ ＤＡＣ２５Ｂ的使用方式十分簡單，先在前方面板將Ｉｎｐｕｔ切至ＵＳＢ檔位：
http://my-hiend.com/markho/2012-09-2...(1024x683).jpg
在後方將ＵＳＢ輸入街上Ｍａｃ ｍｉｎｉ的ＵＳＢ Ｐｏｒｔ：
http://my-hiend.com/markho/2012-09-2...(1024x683).jpg
在Ｆｉｎｄｅｒ下選擇系統偏好設定裡面的聲音：

進入後在輸出上選擇ＵＳＢ Ａｕｄｉｏ：

接者開啟ｉＴｕｎｅ後就可以聽音樂了：

當然透過ｉＰａｄ進行搖控就不用跑來跑取切換取目了：

Onix的聲音很討喜，溫潤有甜味，好好聽~~~~
漂亮!
話說他的訊號輸出是有經過前級控制還是直出呢?
音控是給耳擴用的~~~~~~~~
跟以前的版本一樣，DAC25B的耳擴部份仍跟DAC的聲音非常一致
推HD800也沒問題，這樣聽也很讚

而且DAC25B的解析也明顯比以前的DAC25A好上一截喔~
想問一下dac25b走同軸或光纖哪個比較建議
最近剛入手當客廳訊源, 前一級是oppo 103d
有推薦數位訊號線和電源線嗎?
一般順序是
Aes 同軸 最後是光纖

還有問題想問一下
從onix國外網站
http://www.onix-hifi.com/?p=3315
DAC25B所使用的dac為 PCM1796
你們藝聲官網
http://www.soundart.com.tw/products_...=121&g2=32&g=2
DAC25B 所使用的dac為 PCM1792
想問一下為什麼會有此差別?
就現有代理商的產品內部看是1792
國外有可能是誤植

感謝站長熱心的回應!!!!
Onix是很超值的選擇.............再次推薦！

cp值不錯能附遙控器就更好啦
這台DAC附遙控可能用不太到
因為前面的音量是耳擴用，原則上人不會離DAC太遠
若是input或是升頻的切換，頻率一般來說不會太高，所以就沒附，反應在更便宜的售價上 (羊毛出在羊身上)
但還是有預留了搖控的空間(前方有IR接收)，若用家有其他Onix器材有附遙控器了，就可以一起用，或是真的很想要，也可加錢買一隻
