Package Contains

  • HIRESFI USB DAC 5122A (micro-USB Socket / RCA Out)
  • Small velour bag

HIRESFI USB DAC 5122A was developed by High-End Audio enthusiasts in the purpose of making an extremely good miniature USB DAC with RCA out.

HIRESFI USB DAC 5122A utilizes the PCM 5122A Digital Analog Converter from Texas Instruments in combination with a fully USB Audio Class compatible USB codec. Having this in the box, this DAC works seamlessly with most operating systems right away - without the need for proprietary drivers or apps. With its premium IC from TI this HIRESFI USB DAC scores with 112dB DNR in the Champions League for HiRes audio DACs. With compressed music or lossless FLAC up to CD or DVD resolution an impressive gain in sound performance can be experienced compared to conventional DACs.

8 x Oversampling Digital Filter in 348kHz: HIRESFI USB DAC 5122A up-samples audio data in real time on the IC to 8 x 48kHz. It utilizes its internal DSP-filters in 348kHz for crystal clear and deep black sounding. Negative influence originating from USB drivers by foreign suppliers or from jitter on the USB Bus is therefore prevented.

HIRESFI USB DAC 5122A offers pleasures of finest sound in studio quality - and pure lust for life.

Not only the electronic components have been selected from the higher and exclusive end. Even the small black box with approximately 50 gramms is made from valuable and stable full aluminium profile. HIRESFI USB DAC 5122A just needs the power from the USB bus. Power is internally processed and regulated by a fully integrated low noise regulator for perfect fit with the DAC IC.

In combination with a decent power amplifier, driven by PC, Notebook, Tablet, MacBook, iPAD, ... HIRESFI USB DAC 5122A will deliver an outstanding sound spectrum.

Typical Applications

Windows, Android, Linux, macOS, ... all plug & play

Volume level and sound is controlled by usual control keys on your computer.

HIRESFI USB DAC5122A is made for applications with streaming and lossless FLAC media up to CD (44.1kHz) and DVD (48kHz) quality. Its USB audio interface is fixed at 48kHz 24Bit and thus only relevant bit-information is passed on to the DAC, which then up-samples audio data internally to 384kHz itself. This way HIRESFI USB DAC5122A shapes an optimized analog output signal with its own, vast high-end algorithms.

Some pretty sensible features have also been addressed with HIRES USB DAC5122A: premium resolution of finest sound details with 112dB signal-noise-ratio, soft-mute at the switching on/off and fully compatible USB audio implementation. All virus-proof audio-features natively available in the operating system can be used right away - without the need for proprietary device drivers.

  1. Deutliche Verbesserung des Klangs (von einem Musiker und mir gehört).
    Das Preis-Leistungsverhältnis ist sehr gut. Die Tonqualität verbessert sich deutlich. Ein Musiker und ich (Hobby Musiker meinerseits) haben einen Vergleich gemacht. Musik in CD Qualität und mp3 gute Qualität auch. Der Hiresfi Dac 5122a wurde mit dem mitgelieferten USB Kabel an den USB 2.0 Ausgang des Rechners verbunden. Darauf der Dac mit qualitativ relativ guten 2 Metern Chinch Kabeln mit der Stereoanlage verbunden. Dann den Rechner und die Stereoanlage gestartet. Die Hauptlautstärke des Rechners auf maximal 85% gesetzt um Verzerrungen zu vermeiden. Zuerst die Musik über Toslink optisches Kabel gehört. Dann über dieselbe Lautstärke die Musik nochmal über den Dac gehört: Gefühlt etwas lauter der Eindruck, der Bassbereich wärmer und voller, die Mitten auch voller und die Höhen feiner. Insgesamt differenzierter in den 3 Frequenzbereichen (Bass, Mitte und Höhen), mehr Details und gefühlt mehr im Raum die Musik, entspannter. Ich bin sehr dankbar mit diesem Dac. Es ist eine große Freude damit Musik und Film zu hören und genießen. Und gebe sehr gerne die volle Punktzahl.
