Verdict
The clearest difference is rating: Sound Amplifier at 4.6 against DXO's 2.6. Sound Amplifier also leads on update cadence (every 2 weeks vs every 64 months) and ratings volume (1.2K vs 11). DXO's advantage is in-app purchases (none vs 6) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.
