The PREMIUM PREAMPLIFIER redefines the state of the art.
It's extraordinary quality reaches the standard that will remain intact over time.

Like any product Harmunia is made entirely by hand in our workshops in Florence.

The PREMIUM PREAMPLIFIER has great presence, definition, transparency, concreteness, bandwidth and resolving power, all combined in a sound environment of a purity and naturalness disarming.
The grain and electronic artifacts are simply absent. The result can be defined to listen, without any exaggeration, disturbing.

The impact of low, their depth and control are startling, while music ebbs and flows with a dynamic that is rarely found outside the concert halls.

Normally the distance between live music and music reproduced immediately obvious to listening, even in the presence of quality appliances. On the contrary, the PREMIUM PREAMPLIFIER returns - with a level of quality that surprises the listener - the intentions and the will of the musician performer regarding timbre, dynamic, expressive sound.
What emerges from a background completely "black" is the soul of the live sound as we perceive the conductor or performer.
Only a direct listening allows you to fully appreciate the performance of our equipment.

The aesthetic is in line with the traditional look HARMUNIA, all centered on simplicity and quality of performance.

Knobs Billet, the attenuator gain to 45 steps in configuration LADDER, frame Preamplifier electrolytic copper 2mm thick for RFI shielding to the top, to ensure a low resonance, improved electrical ground to the preamplifier.

The Premium Preamplifier circuitry uses a tube triode single-ended class A without counterforce and mounted on breadboard special resonant 10hertz.
The output transformers built to specification, doubly shielded with copper and mu-metal, muted internally and also mounted on resonance with 10 Hertz.

Is fully wired flush.
It has the power to completely separate valves, with polypropylene capacitors in oil bath, also damped with innovative technical solutions acquired through years of testing.

The valve rectifier was also mounted on a base that has a very low resonance realized with a technique to "sandwich" (formed by copper and damping material) and installed on special media.

Components used have excellent performance thanks to the materials they contain, like resistors tantalum, the
wiring for the signal are silver ultra litz 5n, while those of the power supply are copper litz UP-OCC 6n and all contacts are made of copper, silver and copper / gold in the absence of nickel.

These technical features of our creation. But, as for the music, the description and words can only provide information, data, important information, but not a decisive choice.
it is only with the listening experience that you can grasp the quality of a sound that manages to revive and return to the listener the deepest emotions hidden in a recording.
Like music, the quality of Harmunia PREMIUM PREAMPLIFIER to be truly appreciated applies to be heard.
Is an amazing experience.
