Wireless Digital Integrated Amplifier


  • 176.4 kHz input sampling rate.
  • 3GB/s over-sampling rate for smoother, more natural reproduction.
  • An on-chip clock reference signal for synchronizing incoming digital audio data -Data re-clocking results in ultra low jitter performance.
  • 100% linear frequency and phase response (+/- 0.1dB from 20 to 20kHz)
  • THD+N = 0.07%
  • Signal-to-noise ratio > 95dB A-weighted.
  • High-quality, audio-grade parts throughout.




The NuForce DDA-120 integrated power amplifier accepts analog, digital and Bluetooth audio inputs from computers, consumer entertainment and streaming devices without the complexity of an audio/video receiver.

Technology & Craft

Futuristic Design

The DDA-120 does not require the typical DAC stage found in most of today’s digital audio products. Rather, its PWM power amplifier stage is modulated directly by the incoming signal, and the digital-to-analog conversion takes place at the speaker outputs . In effect, the PWM power amplifier stage operates as a power DAC.

This effectively eliminates the DAC-related problems that have plagued serious listeners in the past Fewer parts result in a more direct signal path, resulting in benefits passed along to you: exquisite sound at an affordable price that delivers more digital audio “bang” for your buck.

Designed for the Future

The DDA-120 accepts a full compliment of sources -. One RCA analog, four digital via one USB, one coaxial, two optical inputs, and one expansion slot for NuForce’s BTR-01 Bluetooth receiver dongle Taken together, the numerous inputs provide truly unprecedented flexibility for your home audio and A / V needs. Moreover, with the included remote control you can easily select all inputs and adjust volume from the comfort of your listening chair.

In addition to all the above, the innovative DDA-120 will effortlessly drive your loudspeakers with superb dynamics and transparency via a robust 50Wrms / 250Wpeak power capability per channel.

If you’re seeking a moderately priced integrated amplifier that represents state-of-the-art design and offers true high-end audio quality, features and convenience … all backed by solid performance … the DDA-120 is clearly the ideal choice.

Featured in Sound & Vision’s New Gear section: “Wishing for Wireless: Adding Bluetooth streaming capability – with aptX support – is a simple matter of plugging the included BTR1 receiver into an expansion slot on the back of the amp.” "
The DDA120 was a superb audiophile-quality integrated amplifier, reproducing high-quality stereo recordings with excellent fidelity, but it was also an outstanding everyday amp for watching broadcast TV or the occasional movie. "
It sounds good enough, it has the features, and it looks good. Its compact exterior makes it easy to position, and it can easily be hidden away in a bookshelf. Not a bad buy, actually. A strong 4 out of 6 stars. "
The bass response is bigger and more voluptuous than you would think, the mids are alive and dynamic, and the treble has just the right amount of energy and detail. "
無論外觀、推力還是聲音,都遠超出預期的好。,DDA-120標示50W一點也沒有灌水,確實能帶來豐富的細節與足夠的動態,就算比較難推的Megan VIII,一樣也能發讓人滿意的聲音,表現完全超越體型,甚至價格的標準。 "
“The DDA120 is a perfect DAC and amplifier, because it is featured with five inputs, Bluetooth function and a powerful amp in a compact chassis.” "
Optoma NuForce DDA120 并不只是好看和好听而已,而且其接口丰富功能多样,让 DDA120 能完全融入到家庭娱乐之中,你可以有很多种使用他的方式。而蓝芽功能也十分实用,除了简便联机外,音质也是可圈可点,让 DDA120 全面性更提升,是实用性和性价比都很高的居家音响产品。 "
“Here a compact amplifier that is able to make great music with talent. It is relatively powerful and shows a very good performance and great control.” "
"The NuForce DDA120 is a versatile device with a few strong features. This product is extremely flexible and has a very energetic sound.“ "
自從Optoma入主NuForce之後,產品造型開始走向極簡風格,這台DDA120就是最好的例子。外殼使用鋁合金打造,表面施以噴砂處理,通常在高價音響器材上才能見到這種質感,沒想到定價不高的DDA120做工也如此用心…. "
