Product Description

ADL X1 Portable Headphone  Amplifier for i-device with USB DAC

Headphone listening is an intimate sonic experience and most enthusiasts employ headphone amplifiers and a good pair of ‘phones– like the ADL H118! The headphone amplifier determines the quality of sound in hand with the headphones.

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, iPad devices. The X1 also runs 24/192 SPDIF with high-resolution files from PC via the PC’s 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 USB source signal 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.

    I had been looking for a portable audio amp/DAC that accessed the digital files on my iPods rather than simply amplifying the music from their onboard DACs. When I was looking around I also became interested in a small headphone amp/DAC such as a Dragonfly for use with my laptops. On the heels of that I felt it would be great if I could that same DAC as an interface between my computer and home stereo. I thought all this was too much to ask from a single device until I stumbled on ADL’s X1. It covers all those bases and does a remarkable job of each. It drives all my headphones, from efficient in ear monitors to my power hungry over ear HDs. This is a fantastic and flexible headphone amp/DAC, you should try it!
