What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Volt 2 USB Audio Interface
Only one whitelisted tester, SoundGuys, covers the Volt 2, and only as a pick inside a buying guide rather than a dedicated lab review, so there are no measured numbers. It endorses the Volt 2 as a capable sub-$200 Focusrite Scarlett alternative with 610-style preamps. No cross-source corroboration exists on the whitelist. (1 sourced review.)
Praised: Capable, well-priced sub-$200 alternative to the dominant Focusrite Scarlett; 610-style vintage preamp emulation adds switchable warmth/color; iPad compatibility, USB-C, and MIDI connectivity with 24-bit/192kHz AD/DA.
Studio 24c
Only one whitelisted hands-on review of this exact model survived verification (MusicRadar, Sept 2023). It calls the Studio 24c a hard-to-beat sub-$100/£100 2-in/2-out interface with clean, high-headroom PreSonus mic and instrument preamps, full MIDI I/O and streamer-friendly Loopback routing, docking it only for closely-spaced controls and a rear-mounted headphone jack. The review is qualitative with no published lab measurements (latency, dynamic range, THD). (1 sourced review.)
Praised: Superb, clean sound with high-headroom PreSonus mic and instrument preamps; MIDI in/out adds versatility over similarly priced rivals; Loopback routing is genuinely useful for streamers and podcasters.
Flagged: Five rotary knobs and the 48V button are placed too close together; Headphone jack is rear-mounted rather than front-facing.
