The NuPrime IDA-6 Integrated Amplifier

Class A+D Integrated Amplifier with DAC

The NuPrime IDA-6 consists of an integrated amplifier and digital-to-analog converter that decode PCM 384 and DoP64 with the convenience of wireless audio in a small, handsomely designed home stereo component. NuPrime's Single End Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology. The IDA-6's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believed.

Class A+D Integrated Amplifier with DAC

IDA-6 utilized a design technique that allows it to perform PCM 384 and DoP64 decoding that measured up to the performance of high-end DAC. A SRC (Sampling Rate Converter) FPGA IC chip up samples the input signal to gigahertz range before it is down sampled to a fixed PCM sampling rate for ultra-low jitter and distortion rates. This classified fixed sampling rate simplifies system design that resulted in sound quality that is unprecedented for an integrated amp at this price point.

With all stages in one chassis, the IDA-6 avails itself of the shortest possible signal paths in order to facilitate low levels of noise and distortion for a black-velvet background to music. 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.

The NuPrime amp circuit improves on traditional class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 500kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. In addition, a new low noise switching power supply is designed specifically to complement the IDA-6 amplifier.

The IDA-6's frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights. The IDA-6's features and specifications have few equals. Just one audition will convince you that the IDA-6’s performance is unmatched at this price point.
