The NuPrime IDA-8 consists of an ultra-low-noise integrated amplifier and digital-to-analog converter that decodes USB PCM 384 and... DSD 256 with the convenience of wireless audio in a small, handsomely designed home stereo component. NuPrime's new Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology in a milieu of un-measurable noise. The IDA-8's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to be believed. With all stages in one chassis, the IDA-8 avails itself of the shortest possible signal paths in order to facilitate vanishingly low levels of noise and distortion for a black-velvet background to music. The listener's initial reaction might very well be "I can't believe my ears!" The IDA-8's low noise floor is further complimented by an innovative volume control based on a thin-film resistor design that positions a single resistor in the signal path for each volume setting. Volume changes occur in 99 precise 0.5dB increments for each input's individually adjustable volume level. Precise level matching is a breeze, as is the user's ability to make comparisons of music sources. Innovative FeaturesUltra-Linear Class A Module (ULCAM) achieves audiophile-quality sound with Class-D's dynamics, speed and efficiency State-of-the-art DAC supporting USB PCM 384 and DSD256, that is also capable of decoding DoP formats via coaxial and optical inputs THD+N lower than 0.005% with a -130dB S/N ratio NuPrime SRC IC chip provides FPGA processing with ultra-low jitter and distortion NuPrime vibration-free isolation feet (patent pending*) Analog line-out (Sub Out), with 3X the standard output power, provides impressive lows and a wide sound stage specifically designed for subwoofers Four digital inputs and one stereo input for complete system read more
