Introduction
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. 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. 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.
