NuForce-DDA-100-amp-2-shot.jpgNuForce recently introduced a direct-digital integrated amplifier that the company claims marks a new juncture in digital sound. The new design converts the digital audio signal into analog form at the last possible stage--the PWM amplifier output-- allegedly giving listeners the same level of performance as far much more expensive audio gear.

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.

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 flexibility for your home audio and A/V needs.

The DDA-100 will drive your loudspeakers via  75-Watt RMS and 250-watt peak capability 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 currently available worldwide for a suggested retail price of US $549.00.
