Acoustic Research AR-M2

Acoustic Research這個美國音響老品牌,近年重新以DAP出發,他們推出的AR-M2可以說是近期DAP市場上的亮眼新星,AR-M2採用Android作業系統,提供了最直覺化、最便利的操作方式,而且能夠藉由Android系統的高度支援性,透過第三方軟體或其他程式來使用擴充功能,例如Youtube或Spotify等線上影音平台。

AR-M2採用Burr-Brown PCM1794A DAC晶片,最高可支援24bit/192kHz取樣率,DSD128與DXD檔案也都在它支援的範圍內,為了針對44.1kHz與48kHz兩種不同倍率的取樣,AR-M2還加入了一只取樣轉換晶片Cirrus CS8422,並且透過TCXO振盪器來分別處理兩種倍率的取樣格式。放大電路部份佔據了AR-M2電路中相當大的區塊,首先透過兩枚Burr-Brown OPA2134將訊號放大,之後再將訊號送至TI TPA6120A2的耳機放大電路,並且透過了類比的ALPS音控來調節音量,整體的做法非常傳統,也確保了AR-M2的好聲基礎。AR-M2有很出色的驅動能力,它的輸出達到每聲道327mW@32Ω,可以說是DAP中最出色的一款。

AR-M2的聲音非常富有類比味,濃蜜厚實的中頻顯得相當討喜,並且有很好的凝聚力,同時呈現出晶瑩剔透的顆粒感,它的高頻細緻度夠好,而且擁有出色的延伸與解析力,但不會顯得尖銳或刺耳,既表現出了數位流Hi-Res的特質,又擁有類比時代的味道,融合了兩種時代的優點,讓音樂有了良好的詮釋,在目前的DAP市場中顯得更加獨特,不同於他牌產品分別向數位或類比兩個極端靠攏,而是結合了數位與類比的特色,發揮出獨一無二的優質好聲音。
