What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Universal Audio 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.
