@kenjit As for the sound quality, this is not something which can be matched other than using trial and error because nobody knows why amplifiers and speakers sound the way they do.
That's what I'm talking about. The only way to get the most out of your speaker is to have an amp and crossover that are designed for that speaker and its drivers. Some say on this thread that high end audiophiles aren't confused, seems like trial and error over such expensive equipment is the definition of confusion.
