## What reviewers say

**Scarlett Solo 4th Generation** — Only one whitelisted tester, SoundGuys, published a hands-on review of this exact model (Scarlett Solo 4th Gen), testing it over one week. It calls the unit a safe, affordable, easy plug-and-play entry interface with quality mic preamps, while flagging the missing output meter, Auto Gain and Clip Safe. No lab measurements were taken. (1 sourced review.)

**SSL 2+ MKII** — Two whitelisted hands-on reviews (Sound on Sound, MusicRadar) both recommend the SSL 2+ MKII, praising its intuitive physical-controls workflow (no companion app needed) and clean, crisp preamps. Neither published its own lab measurements, so the dynamic-range gains they mention are SSL's own specs, not independently verified. MusicRadar's main gripe is the plasticky, lightweight feel versus all-metal rivals. (2 sourced reviews.)
