Beauty through technology. The NotePad series uses the most advanced audio power amplifiers and power supply technology in the world to provide an incredible power density of up to 250W per channel into 4-ohms from footprint smaller than an iPad.
Our fully custom low phase noise clock circuitry keeps the system jitter to vanishly low levels so that all you hear is the music. Whether connected wirelessly or cabled, vocals are strong, clean and provide a 3 dimensional projection into the soundstage worthy of any high end system. Our zero ripple power supply topology provides tight punchy bass to excite while the Stream DAC remains linear all the way down to -140dB. The NotePad is is a truly stunning addition to the Chapter product library.
