The H 3.1 MK3 Power Harmonizer

Music reproduction needs of 2 signals, one constant and one modulated.
It is clear that the modulated signal is the one coming from the source, let it be a turntable, a CD player, a streamer or whatever.
The other signal is electricity. Not less important but most neglected because considered as a given one. But it is fed in each single component of the HiFi chain.
Then, if we have the chance to improve the electricity, we do have the chance to improve the output of each single component of the HiFi chain.
Protects Your Hi-Fi chain from voltage spikes and power surges.
Stabilizes the current.
Eliminates the interferences from industrial and home equipment.
Keeps the harmonic richness of the music signal.
Dramatically improves the performances of Your audio and video equipment.
Boosts the emotion of music.
It delivers You the emotion of live music: the whole equipment disappears in the room.
The line of power harmonizers focuses on the electricity: finds cute ways to improve it.Der Power Harmonizer konzentriert sich auf Stromqualität: eine spannende Möglichkeit diese zu verbessern.L'armonizzatore si concentra sulla qualità della corrente: usa soluzioni interessanti per migliorarla.
