“High End Electronics born in Italy”

Unison Research was founded in 1987 by a group of passionate audiophiles led by Giovanni Maria Sacchetti. Born in 1945, Giovanni Maria Sacchetti devoted himself at an early age to the study and design of hi-fi systems, combining his interest in electronics with a passion for music inherited from his father, an expert pianist.

“This amplifier is more than just a nice tube integrated; it is a work of audio art. It’s an amplifier that should be put on a pedestal with a wonderful painting above it.” –  tonepublications.com

Teaching and designing amps for 25 years, Giovanni and his company have thrived and gained recognition as an experienced manufacturer of high performance and high quality amplifiers.

Focusing on hybrid and tube amplifier design, the company based in Italy continues to be a leader in the industry with a worldwide reputation for excellence. Our clients are always charmed and seduced by the beauty of the designs and the lush realism from these amps.

A good friend of mine used to say, “Not all recordings are equal, that’s why God made tube amps.” – positive-feedback.com

By the way, special thanks to Graeme for his caffeine fueled audio rants!
Not only do they have great entertainment value, they’re also spirited and come from the heart.
Maybe not always to everyone’s liking but I truly appreciated them. A great experience!

“Just a quick note to express my appreciation for the dedicated attention I received from the friendly folks of Coup de Foudre, particularly Graeme, and Jennifer. You spared no effort to ensure my complete satisfaction, and that's exactly what I received, complete satisfaction. Although I live 3 hours away from your High End store, it's…”
