Act 2 could potentially be stronger with an incredibly retarded range of possible combinations of sound attacks, In a Silent Way is pretty much the same stand and is used much better. It's like if Araki was re-reading his own work and realized Echoes Act 2 was too strong so he rewrote it as a villain.

Shit, he could even write some "heavy" onomatopoeia and it would already mog Act 3.
