NuForce DiaTM

Digital Input Amplifier

The NuForce Dia accepts audio input from your favorite consumer electronics products via its optical or coaxial digital input and converts the signal to high-quality audio using its 24bit/192kHz D/A converter. Dia's high-performance 24W stereo power amplifier drives powerful, crystal-clear sound through your existing speakers for ultimate audio performance from your:

  • Wide screen and high-definition TVs
  • Satellite receivers and set-top boxes
  • Gaming consoles
  • Blu-Ray/DVD/CD players
  • Media streaming devices like Airport Express and Apple TV

We recommend the award winning DDA-100 for users who need more inputs and bigger power.

By performing high-quality digital-to-analog conversion separately, Dia adds a new level of realism and exquisite detail to virtually every component you may already own—without any additional receivers or peripherals.

For example, by connecting your flatscreen TV's digital audio output to Dia driving your pair of high-quality speakers (including an optional subwoofer), you can get high-performance stereo sound without having to set up a home-theater receiver.

You also can connect any wireless media streaming devices such as Airport Express and Apple TV to Dia and a pair of speakers to form a compact, high-performance wireless system that fills the room with sound.

Whatever component you want to plug in for exquisite audiophile-quality sound—without the bulky receiver—Dia translates the digital audio signal to analog sound via high-quality 24-bit D/A converters that operate exclusively at the data's native sample rate for maximum clarity and detail.1

1The maximum sample rate currently supported is 24-bit/192kHz.

"[4 Mice Rating!]...the Dia is a real winner...Sonically, the Dia was my favorite of the bunch, demonstrating the impact of the design changes introduced since the Icon-2. And as with the Icon-2, there are some great full-size integrated amplifiers in this price range, but few (if any) will have a built-in DAC, and none will have such a tiny footprint on your desk..."“When used with popular,
