## What reviewers say

One whitelisted tester, Sound on Sound (January 2025), published a hands-on review of the Apollo X Gen 2 range that explicitly covers the Twin X Duo Gen 2 (listed at GBP1135/USD1199). It calls them the best-sounding Apollos yet and singles out the deep, effective Sonarworks SoundID speaker and headphone correction baked into the interface DSP. No lab measurements were published. (Based on 1 review, 2025-01.)

Praised: Best-sounding Apollo yet, with very good audio specs; Deep, effective Sonarworks SoundID speaker and headphone correction baked into the interface DSP; Versatile Assistive Auto-Gain across Unison preamps.
Flagged: No Thunderbolt cable included despite the four-figure price; Monitor Correction on/off status not clearly indicated in Console (especially headphones); Auto-Gain not yet supported on all Unison plug-ins and not fully foolproof; Built-in headphone amps lacked power for a very loud drummer.
Disagreement: Single-source verdict, so no cross-source comparison is possible. Sound on Sound's take is uniformly positive with only minor usability caveats.
