Here’s a new feedback today. He shared his feedback after receiving Fiio M15 with Fidelizer Ultimate Mod for about 2 weeks.

It’s taken a few days to settle/burn in but now, it’s sounding great! Quite high resolution and ‘speed’ but lovely tone, and musical timing. Obviously I can’t compare with the unmodded M15, but it’s streets ahead of my old M11 (as it should be!).

Thanks!

Fiio M15 is the hardest DAP to crack for modification. I’m glad to hear this ultimate project went well without issues. It’s tuned to be highly resolving with great musicality. 🙂
