NuPrime IDA-6


Class A+D Integrated Amplifier with DAC and Wireless Port

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.

SKU: NP-IDA-6 Category:


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. Such design and the resulting sound quality is unprecedented for an integrated amp at this price point. With all stages in one chassis and the shortest possible signal paths, the IDA-6 therefore exhibits low levels of noise and distortion for a black-velvet background to music.

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, while most competing class-D amps switch at 400kHz 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.
