Here, we describe our new products.

model S50x ― "Smart" Products Line

Named "Smart" is derived from modern Japan, especially in the Edo era to represent what "essence" and "stylish". In this products line, we aim to be condensed to a timeless design not too flashy, yet are required minimum of sophisticated features. Audio equipment is usually, does not exchange many times in a lifetime. So our customers, to enjoy the music to cherish the ones you like, this may also be wants of us.
As you see each page is about the features and functionality of each product, here you like to touch on briefly the overall design concept. "In order to enjoy the music, we do not need things exaggerated" in theme, enjoy the music really need a minimum of equipment configuration, yet decided to allow flexibility in system configuration according to the needs of our customers. For example, listen to CD music on the speakers, CD player, amplifier, loudspeakers, but is the minimum required. If each element give you enough to play each of the function, you just need to connect them with a minimum of cables. Complex wiring and, there is no nothing special equipment separately necessary. Equipment with each of its due role is, and finished products to condense the only thing "sound was the best" in repeating the various prototypes. Thus was able to announce the new series to everyone, we think happy from the bottom of our heart.

model S501/S501i "air" ― Smart Headphones/Line Amplifier

The electronically controlled attenuator and the input selector with no mechanical contact, has achieved dramatically powerful, lucid and clear sound quality than mechanical volume control and switches. The sound with a sense of high speed, warm and relaxed does not feel sluggish seems to have been driven almost in the air. Also we have released a new model for current-mode audio interface (S501i). See in detail...

model S502/S502i "ether" ― Smart Integrated Amplifier

The electronically controlled attenuator and the input selector with no mechanical contact, has achieved dramatically powerful, lucid and clear sound quality than mechanical volume control and switches. Reduced many kind of elements that causes the stagnation of the music signal to reproduce the natural depth and spread stress-free, "elegant" and "refined" sound. Also we have released a new model for current-mode audio interface (S502i). See in detail...

model S503/S503i "spiral" ― Smart CD Player (DAC included) / CD Transport

While inheriting the sound quality of the model S303A "notebook", also non-oversampling D/A converter and the power supply unit is built in a compact size, and finished as an integrated CD player. The techonlogy of the low noise thorough investigation, was to further improve the fine expressive power. So that it can be also utilized as a high-end CD transport, two digital coaxial outputs (S/PDIF) for complete dual monaural system. Available two types of audio interface, voltage-mode signaling (for conventional audio interface, S503) and current-mode signaling (for a new audio interface, S503i). What more does not make for a while. See in detail...

model S504/S504i "unison" ― Smart 16 bit Non-Oversampling DAC

This small size (100×200mm) DAC, with extra low jitter oscillator and precise crystal to re-clock digital audio signals and discrete transistors I/V conversion (current mirror amplifier with no coupling capacitor), clear voice, stereophonic, more musical and harmonic sound can be heard from 16 bit raw data. There are 4 variations (version) in this product for each input (coaxial S/PDIF, USB-PC, optical fiber TOSLINK, I2S). Available two types of audio interface, voltage-mode signaling (for conventional audio interface, S504) and current-mode signaling (for a new audio interface, S504i). See in detail...

model S505/S505i "Flügel/Fluegel" ― Smart Power Amplifier with Volume Control [New]

With an analog power supply with a margin, a mechanical attenuators, a high slew-rate amplifier by the fully discrete structure, we have developed back to the basics and newly designed pure analog power amplifier. This can be connected directly to a music source, and it has only the power switch and volume control. Inheriting the "Smart" line, the sophisticated design exists only for listening to music. For those who want a bit more power, this amplifier has 25 watt output. There is more precise expression power and dynamism than ever, and it is characterized by massive sound quality. Besides conventional voltage-mode signaling type, current-mode signaling type can be selected. If you combine with an optional input selector (model S506/S506i), you can also switch the music source. As an amplifier to listen in the listening room, you will not need anything more than this. See in detail...

model S506/S506i "switchgirl" ― Smart Input Selector [New]

When used in combination with a power amplifier model S505/S505i, with this input selector, you can switch three music sources. In switching signal systems, adopting a long life, high reliability reed switch (contact: ruthenium) in which an inert gas is sealed in the glass tube, the deterioration of freshness is very low. It is a high purity input selector which is almost indistinguishable from the direct connection without any inclusion between the music source and the power amplifier. Besides conventional voltage-mode signaling type, current-mode type can be selected. You can purchase it separately so that it can be used even in combination with other systems. See in detail...
