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.

Using Bluetooth and WiFi Audio Receivers and Dongles
NuPrime defined an USB Type-A port to carry S/PDIF data and 5V power for connecting to external wireless audio receiver using just one standard USB cable.
The NuPrime Bluetooth dongle BT-9, D-Stream Audio Primo HD (24-bit/192kHz) and NuPrime WR-100/100D (24-bit/96kHz, co-developed with D-Stream) wireless receivers have a micro USB port that is compatible this specification. This allow a standard off-the-shelf USB-A to micro USB cable to be used for power for the receiver as well as wireless audio data transfer in S/PDIF format.
