Quartorigo – Musical Rhapsody Meets Sublime Style
An astute electronics genius heralding from the unmistakable landscape of Macerata's countryside in Italy; Quartorigo lives by a philosophy that sees superb design the centre-point of refined technical expertise and innovation. Today Quartorigo leads the car audio industry with it's delectable aural solutions, stylistic flow and methodological ingenuity. Constantly redefining the benchmark for tomorrow's car audio and raising the bar to levels many companies simply will never achieve. Such is the Quartorigo way.

Humble Beginnings
A garage, a common passion, a crew of courageous enthusiasts. This is how most great musical adventures commence. However in this instance we're not talking guitars and microphones to arouse souls and blaze, but resistances, transistors, soldering and and most of all the limitless will to create something beautiful. During the eighties the high-end car audio market needed something new. Who'd have thought it would come from here, amongst Macerata's picturesque hills; dreamy car audio products set not only to become benchmarks, but also products able to please music lovers unquestionably.

Desiderio Series – Power Perfection
For the ultimate music aficionado. When Quartorigo set out to develop the Desiderio range of components it didn’t hold back. These amplifiers broke the mould insofar as meticulous quality is concerned, representing the pinnacle of advanced engineering philosophies and materials. Designed to excess by creating a synthesis of technological expertise and aesthetically stunning design; the Desiderio range are not only supreme in their aural output, they're beyond beautiful to behold. They really are the complete package to satisfy all the senses; look, feel and hearing!

Design Ideologies
Music will always be the original soundtrack of our lives. For it’s the true creator of emotions and the incubator of dreams aplenty. It’s an irresistible force which cannot be pushed away, nor can one hide from it; for music is everywhere. It’s as intrinsic to life as is oxygen, and it accompanies us wherever we go.

Music And Culture
When talking Italians you’re talking about a long and prestigious musical tradition which has its foundations firmly rooting in centuries of unique open theatre settings. Thus ratifying the bond between music and culture in a way few other societies are able too. This is where Quartorigo draws its inspiration from. It’s work is aimed at the pursuit of theater sound quality excellence, but inside your vehicle. From a concert hall to your vehicle’s seats, without loosing a single note and allowing you to live out the same emotions. It’s what makes Quartorigo a real conductor seated next to you as you commute.

A No Compromise Piece Of Art
Desiderio is the Italian word for desire and represents every audiphile’s desire to conjugate power and high quality into one amplifier. It is a common misconception that very powerful amplifiers cannot express high-quality. Sure it’s a challenge, but it’s not beyond possibility. With this difficult mission placed in front of the astute Quartorigo engineering team, they got to bringing the concept to fruition.

Passion For Detail
Carefully observing the numerous electrical components and mechanical parts hidden deep inside this unique amplifier will reveal what makes the Desiderio so special. There is a passion for the detail, a dedication to music, a sound refinement, a love for craftsmanship; everything needed to build powerful amplifiers for serious music lovers. The Desiderio really is a mirror that reflects Quartorigo’s philosophies, drive and beliefs. Like a sculpture or a painting is the tangible representation of the artist’s dreams and wishes; the Desiderio is the fulfilling of Quartorigo’s absolute no compromise desire.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Below we expound some of them further.

Dual Mono Power
The Desiderio is made from two completely separated mono amplifiers, laid adjacently inside its unique chassis. The concept is simple; keep everything separate to provide a perfect stage and image and to preserve the sound signal going through the device.

Supplying The Power
The Desiderio has a push-pull power supply with four electric transformers and four MOSFET sections placed for each channel.

Zero Limits
The Desiderio is one of the few car audio amplifiers today to be devoid of any limitations regarding integrated components during its engineering.

Gold Plated Tracks
All Desiderio boards go through a 24 K gold plating process to improve the electrical conductivity of its tracks.

Oversized Everything
The Desiderio uses numerous oversized capacitors on both input and output stage to avoid any difficulty due to heavy loads.

Hand Built Perfection
Every single component in the board of the Desiderio is manually placed and soldered onto said circuit board directly by its creator. It takes eight days to assemble one of these behemoths, during which time no one else is permitted to touch it.

Check And Recheck
Each channel has an individual error checking system that can, in case of failure; deactivate the amplifier in order to prevent damage to the device itself or to other external connected devices.

Every Desiderio is wired to pink noise generator on the input and resistive load, on full load and on the output for 12 hours continuously. Post this test the Desiderio is wired directly to speakers and is set to play music for another 12 hours. In doing this engineers can check the amplifier functions perfectly before shipping.

A Post Script Made By Time
Just to finish all us to leave you with this. Experience is acquired with time and enduring challenges are conquered day after day. Quartorigo systems, like all boutique products; evolve with time but last for life. The company designs and builds it's aural instruments to not only last but prove themselves time after time, list after listen and year after year…
