Product Description

Acoustic Research AR-M20 portable high res music player is a slimmer and lighter alternative to the AR-M2, and is powerful enough to drive a high end pair of hi-fi headphones, as well as lighter weight on ear headphones and earphones.

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.

Premium Components

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.

Key Features

- Rich detailed hi-fi sound from premium Burr-Brown hi-res DAC
- Variable Native Sample Rate with Dual Crystal Oscillators
- Real Touch of Hi-Fi Sound with Linear Power Supply
- Plays Hi-Res Audio Files (FLAC/ALAC/WAV/AIFF/DSD/DXD)
- Internal Memory, Micro SDXC card, or Micro USB memory
- Built-in Wi-Fi Support
- Supports 3rd Party Music Streaming or download APPs
