Acoustic Research AR-M2 Hi-Res Music Player
Despite its slimmer and lighter build, Acoustic Research M20 Portable High Res Music Player is still powerful enough to drive a high end pair of headphones.
For High-End Heaphones
Launched at the Bristol Sound & Vision Show driving a pair of Sennheiser HD800S headphones, the high res music player maintains some of the best features of the existing M2 player at a significantly lower price tag. Acoustic Research M20 delivers 10 to 20 times the power output of hi-res players from the likes of Astell & Kern and Sony, in an effort to deliver better performance with high-end headphones.
The player uses an Android OS with a Qualcomm Snapdragon 400 processor offering Wi-Fi access and web browsing. There's a new DAC, the 32-bit, 384kHz Texas Instruments PCM5242 instead of the PCM1794A found on the more expensive player, but it supports the same hi-res audio formats as its predecessor including PCM and DSD. The ALPS potentiometer volume dial on the top right of the M2 has been removed saving costs via use of the standard volume adjustment buttons instead found on the side.
