Jundac Six

Jundac Six USB NOS DAC

The Jundac 6 is a non-oversampling USB digital to analog converter. Each stage is carefully tuned for the most accurate musicality.

The realisation

On the Jundac 6, the digital stages are reduced to their simplest form. High frequency digital circuits induce electrical, electromagnetic and vibratory disturbances. This electromagnetic pollution ends up sooner or later tainting the sound rendering with unpleasant and artificial colorations. Each function that can be simplified or even eliminated reduces these disturbances.

The design of the Jundac 6 is focused on sound rendering and only on sound rendering quality. For this reason you will find only a very small number of functions and inputs.

The analog stages are the opposite, more opulent, with a comfortable surface area reserved for power supplies followed by class-A, open-loop transistor stages (feedback free). These circuits incorporate innovations such as a split-current power supply and techniques inspired by our Junilight and Juniwave harmonization products.

All these subtleties of realization provide a fleshy sound with natural contours.


The aluminum frame combines soft and hard materials to fight against any form of (sound) degradation induced by mechanical vibration. It rests on a wooden stand (no feet or spikes).

La note du concepteur

Designing a converter for dematerialized music is not an easy task!
If the computer allows to read audio beyond the 16-bit 44.1KHz CD format, it is also the most unsuitable equipment to reproduce music because of its noisy design: microprocessor running at several giga hertz, multiple quartz, chipsets, switching power supply...
There is no more electrically, electromagnetically and vibrationally polluting source than modern computers. If it is easy to get sound from them, it is much more difficult to get quality music from them!
Many discerning audiophiles did not see in this media a serious competitor to a good CD playback. I was one of them and I agree with their disappointment! (smile)

It took four to five years of prototyping, studying almost all technical solutions and a good dose of intuition to go from "correct" to "good", to finally reach a realistic listening.

The Jundac 6 was designed for my personal needs, sober, simple and especially Musical. The only thing that mattered was the sound; there were no marketing constraints. This enthusiasm was shared, so much so that a few copies of the Jundac 6 were sold before it was even in the Junilabs catalog!

To benefit from the qualities of Jundac 6 you will need a computer; the use of the Junilabs Audio player is not necessary but highly recommended.

Whatever equipment you use, don't neglect good sound rendering practices, such as the quality of audio and USB cords, the quality of power cords, the management of vibrations on which the equipment rests, and acoustics adapted to your listening room.
