True, Mr Suyama has no need to detail Fitear's numbers.
Perhaps the MH334 more bassy fits better US or Soul/Rock/Metal lovers which are willing more buying DAPs...???
In my case, Classical Music, I understand that the C435 suits better but we are perhaps a small percentage, thus letting thinking Mr Suyama that the C435 is an aging product.
I prefer a larger soundstage than extended basses, going more to the C435.
