The parts made of natural materials play a natural sound

The parts made of natural materials play the sound which is gentle to listen and fine textured. These PAPER-OIL-CAPACITORS have been tuned exclusively by SPEC. It's a CAPACITOR for the MUSICALITY. Inner KRAFT PAPER brings completely beautiful tone. Mica capacitoers used in SPEC amplifiers are made of highest quality ruby mica.It is produced only at the foothills of the Himalayas. It is made by orogeny of the Himalayas.Mica of high purity is a great benefit from Himalayan orogeny movement and we can hear a profound silence.

The myth that a "CLASS D" is a DIGITAL AMPLIFIER is incorrect. SPEC CORP. has adopted "Pulse Width Modulation" in our "CLASS D". This "PWM" converts "signal amplitude" to "duration switching" through “ANALOG PROCESSING”. This system doesn't digitize the audio signal. This is in fact type of analog amplifier because magnitude resolution is infinite. “CLASS D” with PWM contributes to bring you beautiful acoustical sound. In the past, some audio makers adopted delta sigma modulation for “CLASS D” . This is quite simply “1bit digital” modulation. Combination of switching technology and analog technology makes the sound realistic and beautiful.

We care for our clients by providing them with the necessary information.

On the belief that “ the joy of music is only found in ‘Real-Sound’”, we have been developing and marketing high-end audio products with the wish of communicating and sharing the sensations, also excitement of our “Real-Sound” music with our customers.
Through High End 2014 in Munich, we will demonstrate four integrated amplifier models including the RSA-F3EX, M3EX, V1EX and 717EX.
With extensive use of latest Class D solutions boosting revolutionary speaker drive power and advanced energy-saving performance these amplifiers deliver beautiful tones and fully dynamic sound, in a word true richness of music someone has never hear before.
And also REQ-S1EX, a phono equalizer amplifier fusing the latest semiconductor technology and matured analog technology, will allow the listeners of analog LP records to rediscover the fascination with “the ultimate high-resolution sound”.
