    Following in a long tradition of audio excellence, the NuPrime IDA-8 combines the substance and warmth of an Ultra-Linear Class A Module (ULCAM) in the preamp stage with the extraordinary speed of NuPrime’s proprietary Class-D power for a spacious, transparent, dynamic and luxuriously textured soundstage. The IDA-8’s exemplary distortion numbers (THD+N=0.005% and SNR=-130dB) account for the unit’s peerless clarity. With the inclusion of a DAC that decodes USB PCM 384 and DSD256 in addition to a 100Wx2@8Ohm (180Wx2@4 Ohm) power amp in a 8.5” wide chassis, the NuPrime IDA-8 is truly a technological milestone

    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.


    By utilizing discrete components in NuPrime’s ULCAM circuit, the signal can be fine tuned to reduce noise and provide maximum power.


    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 600kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. In addition, NuPrime’s SRC IC chip provides FPGA processing for ultra-low jitter and distortion rates. Completing the ensemble is NuPrime's new linear power supply with its high-efficiency toroidal transformer for reduced high-frequency noise and strengthened low-frequency performance. The damping effect of the NuPrime isolation feet (patent pending) absorbs and cancels vibrations that degrade audio performance. The overall result is unprecedented transient speed and an almost shocking level of dynamic impact.


    The IDA-8 achieves Total Harmonic Distortion + Noise (THD+N) levels of less than 0.005% while achieving a system efficiency of up to 93%. The IDA-8's frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights .


    The IDA-8's features and specifications have few equals. Just one audition will convince you that the IDA-8’s performance and sophisticated styling are rarely duplicated at any price point.

    Um aparelho que é tb DAC 32 bits e dsd64(sacd), dsd128(2xhd) e dsd256(4xhd)


    A minha dúvida é se ele pode ser controlado por um ipad e se pode virar tb um music server.

    Pela ilustração parece que sim

    por esse preço e a economia que pode trazer tenho que saber mais sobre ele.

    economizo aparelhos e cabos, deve ser algo fantástico.

    É um aparelho impressionante! Entrega 22 Bits de resolução efetiva, algo impensável há 10 anos, o que o torna um dos melhores dacs da atualidade neste quesito.
