Description
 
Goes Anywhere • Stacks Easily • Rechargeable Li-Ion Battery • Digital Inputs For iDevices or PCs • Superb Sound • Perfect with ADL H118s
ADL – Alpha Design Labs – creates innovative, smart-looking components for computer-based systems as well as personal and portable electronics. Tokyo-based ADL by Furutech™ aims high using the best materials and innovative design for an expanding line of Japanese-designed precision products including the superb sounding 24/192 ADL X1 Headphone Amp.
Headphone listening is an intimate sonic experience and most enthusiasts employ headphone amplifiers and a good pair of headphones much like ADL H118. Headphone amplifiers determine the quality of sound in hand with the headphones so both must be technically capable and offer fine sound as well.
The X1 is small, discrete but highly specified with inputs supporting iOS digital at up to 16/48 via APPLE MFI certified USB cable for iPod, iPhone and iPad devices. The X1 also runs 24/192 SPDIF with high resolution files from MAC and PC via USB output. There’s an analog line-level 4-pin 3.5mm input and a 4-pin 3.5mm output for headphones in the 12~600 ohm range. The 4-pin input supports 3.5mm Remote and Mic Earphones. The 3.5mm TOSLINK optical output delivers SPDIF up to 24/192. There’s a convenient GND TRRS switch making it easy to change from one 4-pin set of ‘phones to another. No drivers are needed with Mac computers while a single standard driver is available for Windows computers.
