"Sforzato translates to "stronger than the other notes," "Sforzato" is denoted by "sfz" in music notation. It is not a simple accent; instead, it is used to mark notes which are to be played with one's entire heart and soul."

In September 2009, SFORZATO was founded with the goal of providing playback that brings out heart and soul of music. We have been developing and marketing high-end audio network players that deliver the soul of music to you.

With both the body and power supply housed in robust machined aluminum blocks, a outstanding power supply unit, and a dedicated external clock, this exceptional network music player has everything for sound quality. With an almost ominous silence and stillness just before the start of each performance, it conveys only natural tones and sound fields. Adding nothing and taking nothing away. We provide the finest tools for listening to music.

ES9018S for D/A conversion

ES9018S is used for D/A conversion. The ESS DAC no longer relies on internal jitter removal, running in perfect synch with signal input. The high-fidelity clock and scrupulously arranged clock wiring and architecture ensure perfectly synchronized, jitter-free audio. DSP-00EX boasts two per side for a total of four, achieving massive improvements in dynamic range.

External clock

The unit features no internal clock generator and is driven by 10MHz external input. The attached clock generator is a hi-fi OCXO with low phase noise, a top-shelf master clock generator that is a robust standalone product in its own right. Swapping it out for a PMC-00EX or PMC-02EX will yield even greater fidelity.

Robust power supply

With distinct digital and analog power sources, high capacity transformers, and the high-speed, low noise SiC, the devices drive high power for deep, rich music playback. The dedicated DAC’s analog 3.3V and 1.2V sources feature discrete, feedback-based power with a high-speed, low noise error amplifier, while the analog output uses a discrete, feedback-less power source. On the digital side, multiple hi-fi LT1763 LDOs, courtesy of Linear Technology, regulate POL (point of load). Each integrated circuit works in a discrete fashion without interference from the others, utilizing 100% of their capabilities and ensuring jitter-free playback.

Noise suppression

Using a eight-layer circuit board with a wide top/bottom grand plane allows the majority of digital signals to be arrayed within the mid-layers. Heavy shielding reduces noise to the utmost. Non-magnetic noise absorbing sheets and shield casing cover noise generating components like the CPU, which provides network connectivity, and the clock circuit area, achieving robust noise suppression.
