1- You have DAC + AMP + speakers + objects + micro (complicated transfert function to estimate)
2- You measure speakers (mean...
Did you measure the speakers? Compute the mean from several positions ? Find a delta with difference <0.5 ? And conlude this "Instead, I found that the sound of the D30pro improves in this way" ?
Honestly, if you are not confident don't buy it. Wait and see or choose an equivalent DAC like SMSL SU 9 if you need all options or the excellent E30. Check previous issues with L30, topping had honorable behavior.
