## What reviewers say

**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.)
