Thank you for the comments.
Have you heard Vega or LyraII? Wonder how the low end compares on Jupiter?
Does burn-in benefit a all BA IEM? I thought it most helped the dynamic drivers?
TIA
I have both the Jupiter and the Lyra II, and the Jupiter's bass though deep, does not hold a candle to the texture, timbre, impact and decay of the Lyra II. With that said, I prefer dynamic driver bass over BA bass, and its likely the Jupiter might have a more "accurate" and quick sounding bass, if that's your taste.
The whole idea of burn in is to flex stiff dynamic drivers straight out the factory, I don't believe it affects BA iems,
