    iBasso D2 Portable Headphone Amplifier & USB DAC in Silver

    • D2 Silver
    • iBasso D2+ Boa Description

      iBasso D2+ Boa portable headphone amplifier and USB fed Digital to Analogue Convertor (DAC) in silver.  Get the maximum from your portable audio listening with the iBasso D2+ Boa.

      This unit is the iBasso D2+ with line out analogue audio connection, meaning it can be used as a standalone USB DAC.  For example you can use the D2+ to stream music from a PC (via USB) and feed powered speakers via the D2+ line out socket.

      You'll never want to listen to your headphones without one again


      Now there's no need to compromise when listening on the move with your iPod or computer.  With the iBasso D2+ Boa you can bypass the noisy headphone output on your iPod or computer and feed your headphones with a crystal clear audio signal.

      The headphone output on many portable devices, such as the Apple iPod and many laptop computers, is noisy and introduces distortion to the audio signal.  With a dedicated DAC and headphone amplifier combination, like the iBasso D2+ Boa, you can bypass the standard headphone jack on your iPod or laptop and enjoy distortion free audio.

       iBasso D2 - TrustedReviews Recommended Award

      "The results I had with full-sized phones and the line-out on an iPod Touch were actually quite amazing"

      "The fact is, once you've got used to listening to a decent pair of headphones through the D2, it's very hard to go back.

      "A great sounding portable headphone amp that doubles as an outboard DAC for PC listening. Try it with the right cans, and you'll never want to listen to your headphones without one out again"

      "The resulting sound from the D2 is beautiful - crisp, controlled and powerful. The D2 deepened and smoothed out the bass, gave vocals a significantly richer, velvety-smooth quality and extended the high-end."

      Additional Information

      What is a DAC?

      A Digital to Analogue Converter takes a pure digital audio feed (in this case from a computer) and converts it into an analogue signal that can be amplified.

      Every computer soundcard with a headphone or line level output has a DAC onboard, but in many cases is very poor quality.  The iBasso D2+ Boa upgrades your portable audio system in one step.

      The iBasso D2+ Boa combines a high quality DAC and headphone amplifier in one unit, giving you the ultimate portable audio setup.


      Why use a headphone amp?

      A headphone amplifier takes a line level signal and allows you to drive headphones with it.  Normally a line level signal would not be powerful enough to drive headphones without amplification.

      You can use a headphone amplifier to drive your headphones from many audio sources, such as CD players and portable audio players like the iPod (dock connector cable required).

      Avoid the iPod Headphone Jack

      With the iBasso D2+ there is no need to restrict yourself to listening through the standard noisy headphone output of your iPod or audio source.

      The dock connector on the humble iPod includes a high quality line level output, meant for connecting the iPod to a HiFi via an iPod dock.  With a simple dock connector audio cable it's possible to feed a portable headphone amplifier with a clean line level audio signal, bypassing the headphone output completely.

      A headphone amplifier like the iBasso D2+ Boa is needed to bring a line output to a level that can drive headphones.
