ADL A1 Portable Headphone Amplifier

Some digital enthusiasts require small, portable DACs and headphone amps because they’re always on the move from location to location. Others need flexibility with their digital gear, especially the ability to insert a headphone amp into virtually any system and achieve impressive sonic performance. The new ADL A1 headphone amplifier/ DAC is designed for both of these digital enthusiasts—even if they’re the same person!

The new ADL A1 is a high-resolution portable headphone amplifier and DAC that can be used with Android devices such as ADL’s own X1 and iDevices. The A1 is also DSD-capable when used with either Mac or PC. The high-resolution sound that can be achieved through the A1 makes it perfect for portable audio enthusiasts who use the highest quality headphones to delve deeply into a recording. It’s also ideal for those who want to run DSD 2X on either a laptop or a desktop.
