Bartók APEX is a distillation of our past, present, and future—30 years of innovation in a single beautiful, flexible, and futureproof chassis embodying the essence of dCS. Combining a DAC, Music Streamer, Upsampler, Pre-amp, and (optional) Headphone Amplifier, the Bartók APEX offers a singular experience for headphone and stereo listeners. Now with the APEX Ring DAC, our next-generation DAC hardware, we've once again redefined the state-of-the-art for digital audio. This upgrade allows us to take Bartók world-leading measured performance to a new level—technology that provides an even more immersive musical experience.
APEX is a new, enhanced version of the dCS Ring DAC: the Digital to Analogue conversion system found inside all dCS DACs. First developed for our professional audio products, this unique system has been subject to continuous development and refinement over the past three decades, and remains renowned for its technical and sonic performance.
With APEX, we've reconfigured the Ring DAC's circuit board and developed a new analogue output stage. This has allowed us to further reduce distortion, and increase linearity, resulting in a range of measured and sonic improvements - including an even greater sense of dynamic drive, detail, finesse and vitality.
