Roma Triode


Design and technology

Listening to a Diesis Audio speaker with a directly-heated triode is a unique experience, born from an immense passion for experiencing music as a real event. We work to eliminate the artifacts and colorations of traditional loudspeakers and achieve the highest purity of sound emission, making the listening of any piece a pure emotion.

In addition to innovative techniques, simplicity and the absolute quality of the transducers and materials used guarantee a precious quality that stems mainly from prolonged listening and refinement sessions that have been continuously carried out for years of experience.

The study of the various materials that the delicate musical signal passes through before propagating a note in the air allows us to tune each speaker to transmit an extraordinary passion in every situation, giving “life” to everything presented to the listener.

Roma Triode, the latest extraordinary achievement, incorporates all of this and goes even further, the result of 3 years of work to embed in it a DNA of pure magic, assisted by the world’s most prestigious single-ended triode amplifications. It was custom-tailored to capture every subtle nuance and detail whispered by these marvelous amplifications. Each element of the design has been dissected, tested, and tuned by ear, compared with the best passive components. We have finally chosen to create even the most insignificant element, and the correct direction of each component was identified after careful and critical listening.

Roma Triode has been refined in the last year with the prestigious Japanese Kondo Amplifications. Ongaku preamplifier G70 and fully Kondo-wired. The emotional expression of these wonderful objects for music reproduction is enhanced by the ease with which the speakers allow themselves to be traversed, evoking vibrations of pure emotion, achieving such synergy and magic that cannot be described in words.
