CAS-1 Audio System Features:

The Way The Artists Truly Intended

Enjoy the subtlest nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker so it feels like the artist is performing right in front of you.

Near-field listening

Experience especially rich sound spaces, accurately recreated within 30 to 80 inch of the separate speakers.

Headphone listening

Independent, high-quality DAC and headphone amp deliver High-Resolution Audio headphone listening.

Enjoy chill-inducing sound quality

High-Resolution Audio reproduces every breath, drumbeat, and note, and the S-Master HX™ all-digital amplifier reduces distortion to deliver a recording studio experience on your tabletop.

Enhancing your existing music

DSEE HX™ upscales existing sound sources to near high resolution sound quality, making you feel as if you are really there at the recording studio or concert.

Dual amps for two music experiences

Independent amplification systems deliver outstanding High-Resolution Audio experiences for the distinct amplification requirements of headphones and speakers.

High-Resolution Audio through separate speakers or headphones

Independent speaker and headphone amps deliver High-Resolution Audio through separate speakers or headphones.

More stunning realism than you ever heard

S-Master HX™ full digital amp technology, uniquely developed for High-Resolution Audio, reduces distortion and noise across a wide range of frequencies for rich, full-bodied sound.

Balancing powerful and precise sound

An independent headphone amp and high-end digital-analogue conversion (DAC) drive headphone sound.

Dynamic acoustics create rich soundscapes

Experience your music with live performance richness through stereophonic sound reproduction that recreates the original sound space. Separate speakers distinctively create sound and improve directionality for immersive listening experiences, even in small spaces.

Easily position speakers for best listening point

Place separate speakers 30-80 inches away for optimal listening position. Included brass spikes let you adjust the speaker angle, and included speaker bases provide stable acoustics on any surface

Powerful, extended bass

The customized bass reflex port allows the compact speakers to reproduce deep, satisfying bass.

Well-balanced sound output

Brass spikes elevate speakers to dampen high frequencies and fix woofer-tweeter route discrepancy.

Immersive soundscapes at any volume

The CAS-1 main unit and separate speakers are designed to recreate original sound spaces, delivering tabletop near field listening, even at low volumes.

Uncompromised richness at any volume

Technologies like Pulse Height Volume and Low Volume Mode ensure dynamic audio response even where other digital amplifiers suffer, at low volumes.

Enjoy higher quality listening on various headphone types

A high grade amplifier drives the sound for both in-ear and over ear headphones. CAS-1's dedicated headphone amp and separate high-end DAC adjusts output for more isolated headphone listening experiences. Use the dedicated headphone gain toggle switch to match impedance to headphone type to enhance the listening experience for headphones of varying impedance.

Gain toggle switch

Adjustable gain lets you use your favorite headphones. Use HI/LOW to match impedance to headphone type.

Robust headphone jack

Quality metal parts for stable connections and less distortion. Mini plug socket for wide compatibility.

Easy connections for wireless streaming

Wirelessly connect mobile devices to the separate speakers for convenience and improved sound. Stream your music with detail and clarity using Bluetooth and high-quality LDAC audio codecs.

High quality wireless audio streaming
