Roon Ready Program

Roon is an incredibly rich and engaging way to browse and organize your music. It runs on most Mac, Windows, and Linux PCs, or on other products that include Roon Core.

Roon Ready means that Sforzato players use Roon’s superior technology to deliver a great user interface, simple setup, solid reliability, and the highest level of audio performance compromise. Together, Roon and Sforzato deliver the power, flexibility, and performance of networked audio with the easiest setup and highest reliability available.

MQA (Master Quality Authenticated)

MQA is an award‐winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download.

The player includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. “MQA” indicates that the product is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. “MQA” indicates it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

Ultimate network player, LAN DAC, USB DAC

It’s the ultimate player built to the maximum in a robust anti‐resonant housing with an external clock and a thick front panel for both the main unit and external power supply. This player creates a dramatic sense of silence and “when silence sounds” atmosphere! As well as the natural timbre richness of the music and the stable wide and open sound stage — nothing is added, nothing is colored.

External Clock

A full‐scale 10MHz master clock generator that uses the ultra‐high performance OCXO boasting near phase noise −100dBc / Hz @ 1Hz as a dedicated external clock is available as an option. Of course, you can enjoy higher quality sound by using a higher PMC clock.

D/A Converter

The latest ES9038Pro is used for the D/A converter in monaural, one for each channel. The ESS DAC no longer relies on internal jitter removal, running in perfect sync with signal input. To fully demonstrate the performance of the 9038Pro, which has about four times the current output of the 9018S, a large‐scale I‐V conversion circuit reproduces a vast sound field and a precise and delicate sound image.

Thorough elimination of jitter

The player assumes the use of an external clock (it does not have an internal clock oscillator) that eliminates the interference of internal clocks, and brings out 100% of the performance of external clocks. A special dedicated IC with a jitter of 100 fs (femtoseconds = 1/1000 of picoseconds) or less is used for clock division and distribution, and the clock to a D/A converter etc. has an accurately impedance‐controlled difference. Transmitted by dynamic signal. Jitter is completely eliminated.

Robust housing

Unnecessary vibration and external noise are thoroughly suppressed by the robust front panel made by cutting 15mm thick aluminum and the 3mm thick aluminum housing for both the main body and power supply. The bottom plate is further reinforced with a 3mm thick non‐magnetic reinforcing plate for both the main body and power supply. Coupled with a powerful power supply, it contributes to rich music playback with a sense of speed.

Large−capacity power supply

The power supply is a separate housing, and a total of 7 transformers are built‐in, including a power supply for left and right independent analog circuits, an analog power supply for left and right independent D/A converters, a power supply for the digital section, a power supply for the CPU section, and a power supply for the USB input (optional). The total capacity exceeds 450VA. The ultra‐high speed and low noise SiC Schottky diode is used for rectification.

Inside the main unit, a high‐performance low‐noise LDO LT1763 is used for the digital part, and POL (Point of Load) that regulates in the immediate vicinity of the required part is thoroughly implemented. In addition, the 3.3V power supply for the analog part of the D/A converter has a feedback type discrete power supply that uses an ultra‐high‐speed, high‐precision error amplifier arranged independently on the left and right. Non‐feedback type discrete power supplies are arranged independently for the positive and negative power supplies for analog output. The optimum power supply for each function is deployed in the optimum position.

AC inlet uses JODELICA ETP−600CU as standard.

Discerning internal wiring and output terminals

With the cooperation of Sekiguchi Machinery Sales Co., Ltd. (Acoustic Revive), the internal wiring uses an elliptical single‐wire PC‐triple C wire. The purity of the power supply and signal is ensured by using a laborious wiring method that does not use a connector as much as possible. Two output systems, balanced XLR and unbalanced RCA, are available. Both use Hi‐End terminals.

Careful topology and thorough noise countermeasures

The board is a double‐sided 8‐layer board. The top and bottom surfaces are widely ground planes, and most of the digital signals are wired to the inner layer. Noise is suppressed to the utmost by the strong shielding effect. In addition, electromagnetic noise removal sheets and Finemet beads are installed in place to remove high‐frequency interference.

Software updates

By inserting the USB memory into the USB‐A terminal provided on the rear panel and performing the update operation, you can easily update the software by yourself. It will continue to evolve even after you purchase the device.
