Keces S3

DAC Preamplifier Headphone Amplifier ES9026Pro 32bit 384kHz DSD256

Keces S3 DAC Préamplificateur Amplificateur Casque ES9026Pro 32bit 384kHz DSD256

With the Keces S3 you get an all-in-one device, covering the functions of DAC, preamplifier and headphone amplifier. Carefully designed with high-end components, it provides a high quality sound reproduction that is as rich and precise as it is dynamic.

Its digital-to-analog conversion section is equipped with a 32bit ESS ES9026Pro DAC chip that uses HyperStream® II arcitecture and Time Domain Jitter Eliminator technology to ensure excellent sonic performance. It also enables the S3 to support high-resolution audio streams, up to 32bit 384kHz PCM and DSD256.

On its side, the headphone amplification circuit of the S3 allows him to develop an important power which can go until 2*2000mW under 32Ω. It can thus accompany without difficulty as well very sensitive in-ear monitor as high impedance headphones.

With its extensive connectivity, the Keces S3 is also able to respond to the vast majority of usage scenarios, both balanced and single-ended. On the input side, there are USB-B, coaxial, optical, single-ended RCA and balanced XLR. For the outputs, we can also count on single-ended RCA and balanced XLR, as well as on balanced XLR 4 pins and unbalanced Jack 6.35mm headphone outputs.

The front of the device has a screen displaying information about the playback and a volume control. The latter is associated with a very precise relay attenuation circuit.
