O-NOORUS D3 PRO Amplifier

The O-Noorus D3 Pro is a powerful integrated amplifier based on numerous audiophile components. Its amplification stage features a TPA3255 chip and a PFFB structure with NJW1194 volume control, while its digital-to-analog conversion stage features an XMOS XU316 USB interface coupled with an AKM AK4493SEQ chip. The D3 Pro is therefore capable of supporting sampling rates up to PCM 32bit 768kHz and DSD512 while maintaining an SNR of 105dB and delivering up to 2x225 under 4 Ohms. This small amplifier can therefore fill a large space with sound from a high-definition source, much to the delight of pure audio enthusiasts. Added to this is a QCC3084 Bluetooth chip for stable reception of aptX Lossless, LDAC, and LC3 codecs. In terms of connectivity, it is not to be underestimated, with two USB-C inputs (USB Audio and USB Host), an HDMI ARC input, two coaxial and optical Toslink SPDIF inputs, an RCA line input/output, and a subwoofer output to top it all off. The D3 therefore offers the possibility of setting up a 2.1-channel home theater system to enjoy your favorite movies in addition to its HiFi functionality.
