iFi Audio xCAN is a high power portable dual mono balanced headphone amp, with bluetooth input. Connect xCAN by 2.5mm or 3.5mm included cables, or wirelessly to your phone via bluetooth apt-x for Android or AAC for iphones.
The bluetooth input works better than customers expect, since iFi uses the bluetooth chip only to receive the signal. The signal is taken off the chip and fed to a high end internal dac (digital - analog convertor), providing great clarity and dynamics. This signal then runs through the xCAN's high power headphone amp. Bluetooth to the phone, with your earphones or headphones plugged into the xCAN, can provide a great sound quality upgrade.
You can connect earphones or full size headphones to the 3.5mm output. If you have a special balanced cable, you can connect to the dual mono 2.5mm balanced headphone ouput for even more output and immproved stereo separation.
