Changing engine sound

For the first couple thousand kilometres I had my 2, the engine kind of sounded a bit strained and uncomfortable around 3,000 RPM and higher. Now I've got a little more than 3k km on the clock and the engine sounds quite different. Much quieter at higher RPMs and doesn't sound like it's about to explode anymore, lol. It doesn't sound like I'm hurting it when I bring the revs up high.

Just curious if anyone else experienced something like this. I'm guessing it means that the engine has fully broken in now and has gotten used to my heavy right foot. :p
