Cayin YD01 Fantasy
Our Price | $1,049
YD01 is the stuff of dreams, wielding the magic material that is beryllium. Fantasy's beryllium-plated dynamic driver offers credibility to the idea of a Cayin Audio chain: capably built by the same manufacturer from start to finish, source into IEM.
Cue all associations with beryllium – Fantasy is resolute about its portrayal of detail, with forceful and taut dynamics – and there's still more than meets the eye.
Chambering affairs in a two-way cavity and magnet structure means airflow in the shell is controlled more precisely, as your music flows from the big, composite diaphragm.
The higher magnetic flux as a result allows more linear excursion. Fantasy boasts power, and more importantly, control. Its 10mm driver starts with a sandwich driver core of biocellulose, a paper-like fiber prized in audio for its effective damping at higher frequencies.
This surface is then coated with beryllium for the metal's stiffness, lightness and air acceleration properties. That means Fantasy's driver material combination helps it move as a perfect piston over all frequencies up to and above its working range, keeping distortion down due to cone and modal break-up as frequencies rise.
It's a truly full-range driver, producing bass all the way to a treble waveform perfectly and accurately. Headfonics were the first to hail it for its "beautiful upper midrange and amazing depth of field". In Everyday Listening's simple terms, it's "out of this world".
Fantasy is built in every way as a flagship IEM. Both Advance and Supreme cables from Nobunaga Labs improve this in various ways, as does the myriad of stock tips included.
