• NuPrime IDA-6 with Bluetooth dongle


    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.

    *Hi-Res bluetooth dongle for wireless streaming is included at extra cost

    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.
