Thanks, that's encouraging. I'm glad to hear the A8000 is fast.A8000 decay and settles too quickly. Making it perfect for quick metal tracks. It can keep up without hazing the presentation.
But this very same asset can be a problem when listening for classical tracks. Where you may want things to linger longer.
Great for metal.
I know it's not a bass-head IEM, but does the bass reach deep when called for?
