Onix DAC 25

[Leo Yeh]

去年慕尼黑音響展上首次亮相的Onix DAC 25有了較新的消息，售價約在USD 630，雖然主DAC使用PCM1792 24bit/192KHz DAC chip，也有平衡輸出，但USB部份用上PCM2704，只能到16Bit/48kHz，比較可惜，另就是DAC 25有耳擴功能

這台小弟在某店家聽過,中頻漂亮拿來聽人聲與演歌相當適合,但是高頻不甜低音不勁:(小弟拿搖滾樂聽起來效果並不好,不過定位跟分離度倒有一定水準,建議嗜聽人聲的同好可以嘗試:)

高低音方面、我試過輸出的 op 改成 opa2111kp 會上下各進一大步（好奇一試） 8)

不過另外兩顆（應該是DC-Servo）還是保持原來的opa 2134pa
換2111的話、onix的味道就不見了
