The Twin Pulse isobaric system patented by Andrea Ricci opens up a new scenario in headphone playback. For the first time the dual drive isobaric technique is applied to a full size headphone to obtain a motor unit with an exceptional performance package in terms of acceleration and drive motion control during the sound transient. The Twin Pulse offers playback linearity calibrated on isophonic Fletcher-Munson curves (of equal sensitivity to the human ear) and can therefore be used as a reference tool to verify the timbre reliability of a recording. Twin Pulse doesn’t interpret sound but reproduces it faithfully, so it will be essential to select the components of the audio chain to make the most of its transparency and dynamics. AN EXCEPTIONAL SOLOIST When Andrea Ricci designed the first Twin Pulse unit, he had only one goal in mind: to build the best dynamic headphone in the world and to do so, he had to face the biggest limit of a dynamic headphone: the speed in transients. Everything in this headphone is refined to maximize this aspect, so even the cables can’t be replaced because they are part of a delicate balance. The Twin Pulse has character and demands the most from the other links in the audio chain. To date we haven’t been able to exploit the full potential of this project because every time we raise the bar, experimenting with a new solution, the Twin Pulse amazes us with an improvement well beyond our expectations. A MUST-HAVE CHOICE FOR THOSE WHO LOVE LIVE LISTENING LEVELS The naturalness with which a Twin Pulse can handle music reproduction at realistic volume levels is disarming, so much so that our customers are encouraged to experiment with direct interfacing with small monotriode amplifications designed to drive loudspeakers, with impressive results. AMAZING FUN A listening session with the Twin Pulse never leaves one indifferent, its natural inclination to rhythm involves the listener making him or her soon clap stomp away with the music. The Twin Pulse prefers a passionate approach to music, accompanying the user on an overwhelming musical journey. A PROJECT IN CONTINUOUS EVOLUTION At Spirit we think of the customer as a gentleman driver, to be followed in his musical refinement path, offering an upgrade service that guarantees to our customers the preservation of their investment. The continuous dialogue between company and customers has allowed us to introduce significant upgrades, such as the Alcantara (R) pad and the VPS (Ventilation Pad System) that opens to a responsible My-Fi, making an advanced design, for the first time, fully exploitable even by non-professional users.
