I can understand. I used to really dislike Sonic's voice when it first changed, but now, depending on the scene, he's actually not that bad. In my opinion. It sorta sounds like he hit puberty or something.
...He hit it kinda late (He's like sixteen now) but he sounds like he's grown up a bit. That's one reason I can accept it.
Knuckles I didn't hardly notice a difference, really. But now that I think about it, it DOES lack the gruffness it used to have.
But it's good to hear there is someone who likes this type of Amy voice. ^^
