PreSonus Studio 24chat_bubble_outlineFrom real comments

Latency performance is a standout strength for the Studio 24c. Multiple users independently measured round-trip latency near 9.5-9.9ms at 48kHz with a 128-sample buffer, calling the results 'amazing' and noticeably better than competitors like the Motu M2, which one commenter measured at 15.9ms under the same settings. This low-latency, low-noise performance combined with strong crosstalk numbers made buyers confident in their purchase decisions, with several citing the reviewer's measurements as the deciding factor before buying.

Headphone output impedance is a recurring point of confusion and complaint. Several commenters asked whether their headphones (32 ohm, 150 ohm, 250 ohm, or 300 ohm models like the HD650) would pair well, since the interface's headphone amp has notably high output impedance. Users reported that low-impedance headphones sound out of balance or are driven poorly, while higher-impedance cans like the Sennheiser HD280 Pro (64 ohm) or HD400/560 performed well, and one user avoided newer low-impedance Beyerdynamic headphones entirely because of this quirk.

Mic preamp gain and occasional reliability issues concern some owners. Multiple users noted needing to crank input gain nearly to maximum with mics like the Shure SM57, an issue they didn't have with Focusrite or Tascam units, and one questioned a discrepancy between PreSonus's claimed 70dB gain and a reviewed 46dB figure. Separately, a handful of owners reported troubling reliability problems: USB dropout requiring replugging, crackling/pop noises unrelated to cables or performance, and one unit failing to record entirely shortly after purchase.
