Description
The dCS Bartók APEX DAC Headphone Amplifier is a top-tier integrated digital music player, featuring the advanced dCS Ring DAC™ APEX hardware. This latest iteration significantly enhances linearity, reduces distortion, and lowers noise, delivering a more dynamic, detailed, and immersive musical experience. A key differentiator is its integrated, custom-designed Class A headphone amplifier, capable of driving a wide range of headphones via balanced (4-pin XLR) and unbalanced (6.35mm) outputs. It includes dCS Expanse technology to optimize headphone listening, creating a natural, out-of-head soundstage.
As a versatile network streamer, it’s Roon Ready and provides seamless access to services like TIDAL and Qobuz. It supports high-resolution PCM up to 24 bit/384 kHz and DSD128, with full MQA decoding. A comprehensive suite of digital inputs (USB, AES/EBU, S/PDIF, optical) ensures broad connectivity. With high-quality digital volume control and flexible analog outputs, it can also function as a digital pre-amplifier for speaker systems. Housed in a robust chassis with isolated power supplies, the Bartók APEX delivers unparalleled audio fidelity.
