NuForce Introduces DDA-100 – Digital Integrated Amplifier

NuForce has introduced the DDA-100, a direct-digital integrated amplifier. The new design converts the digital audio signal into analog form at the last possible stage—the PWM amplifier output—giving listeners the same level of performance as far much more expensive audio gear. The DDA-100’s inherently low distortion and noise floor remain in the digital domain from beginning to end, resulting in a wide dynamic range and clarity. By virtue of an advanced adaptation of Class-D design, NuForce claims digital music files are converted directly to analog sound within the final amplifier stage. No DAC- no jitter.
The DDA-100 doesn’t 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.

DDA-100 is designed as a digital-only product for today, and tomorrow’s digital playback components. It accepts four digital sources via one USB, one coaxial and two optical inputs that provide exceptional flexibility for your home audio and A/V needs. And with the included remote control, you can control inputs and volume from the comfort of your listening chair.

Along with its convenience and an innovative design, the DDA-100 will drive your loudspeakers via a robust 75-Watt RMS and 250-watt peak capability per channel for superb dynamics and transparency.

» 96kHz 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

The NuForce DDA-100 costs $549 and will be available shortly.
