NuForce, Inc., has just introduced their new direct-digital integrated amplifier. This new integrated amplifier, named the DDA-100 converts digital audio signals into analog form at the last possible stage to increase performance. The DDA-100’s inherently low distortion and noise floor remain in the digital domain until the PWM power amplifier stage, which provides wider dynamic range as well as increased clarity and detail with lower noise.

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. Few parts results in design simplicity, increase performance and lower cost.

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. A remote control is also included.

The DDA-100 provides an output power of 75 watts-per-channel RMS with peak output of 250 watts-per-channel.

Design features include:

  • 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
  • High-quality, audio-grade parts throughout

The NuForce DDA-100 is available worldwide for a suggested retail price of US $549.00 and will be shipping Aug 1, 2012. Look for more details at:
