Ultra Low Noise Class A+D Integrated Amplifier with
DAC and Wireless Port

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. 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.
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. The “switched resistor” design is
implemented with FPGA chip. 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.
– Ultra-Linear Class A Module (ULCAM) achieves
audiophile-quality sound with Class-D’s dynamics, speed and efficiency.
Extraordinary result of THD+N lower than 0.0015% and S/N ratio of -130dB for
the preamp stage.
