DESIGN NAME: Divaldi Amp
PRIMARY FUNCTION: Headphone amplifier
INSPIRATION: Our first designs were developed in the 80’s, mainly systems designed to play music in clubs, followed by individual AV systems and stage lighting. After over 30 years of experience we have decided to immerse our visions and experiences into something physical and mass but in the same time something that would have its own soul. That’s how the idea to develop high-end devices, which would invisibly connect a human with technology emerged
UNIQUE PROPERTIES / PROJECT DESCRIPTION: AMP – is a small device, embodiment of all dreams, that its designers wanted to create for many years. It is a miniature monument of Polish engineering and artistic thought, contained in an extraordinary, beautiful, minimalistic form.
AMP – is a successful attempt of integrating a genuine headphone amplifier and a phono MM preamplifier in a very modest and small body. What’s even more remarkable, this has been achieved while maintaining dual mono construction.
OPERATION / FLOW / INTERACTION: Easy to use, designed to listen to music through a headphones and mainly from gramophones.
PROJECT DURATION AND LOCATION: The project started in 2015 in Krakow Poland and finished in March 2017
FITS BEST INTO CATEGORY: Digital and Electronic Device Design

RESEARCH ABSTRACT: In 2010 first projects were brought to life in Burgund series, it consisted: an amplifier, preamplifier, loudspeaker and gramophone, mainly developed by Waldemar Łuczkoś. The devices have been featured on many occasions with audiophiles and the at the Audio Show, rising recognition for its acoustic qualities and rare, turntable design featuring two arms. After this first success, we have set the main goal for further development: to combine best sound quality with modern, exclusive and professional performance. Today we are proudly presenting our first devices, which we will systematically develop.
CHALLENGE: The hardest part of design was to find the best electronic components.
