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 xed PCM sampling
rate for ultra-low jitter and distortion rates. This classi ed xed sampling rate simpli es system
design that resulted in sound quality that is unprecedented for an integrated amp at this price point.
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 speci cally to complement the IDA-6 ampli er.
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 speci cations have few equals. Just one audition will convince you that the IDA-6’s performance
is unmatched at this price point.
