January 4, 2023 Comments Off on DAN CLARK AUDIO – DCA EXPANSE REVIEW

The DCA EXPANSE features DCA’s 4th generation planar-magnetic driver and their breakthrough Acoustic Metamaterial Tuning System (see the next chapter). Other key elements are the V-Planar driver processing, which improves bass response and lower distortion, as well as DCA’s TrueFlow V2 technology. The latter increasing the resolution and improving dynamics in general.

The driver inside the EXPANSE is a 76mm x 51mm single-ended orthodynamic one, and the drivers are matched (0,25dB weighted 20-10,000Hz). THD is less than 0.03% 20-20KHz, ref. 1KHz at 94dB. The EXPANSE driver has a 23Ω impedance, with a sensitivity rating of about 86 – 87 dB/mW. The DCA EXPANSE is designed and built by hand in San Diego, California, USA.

The Stealth and EXPANSE headphones in my opinion are super cool and unique in sound, and I hope this review will bring over that feeling. The part on AMTS, used inside the EXPANSE, comes from DCA directly. Feel free to skip to the next part if you’re already familiar with it.
