You guys have to forgive me. I'm like a kid with a new toy. I've always used the built in speakers to play music on my old iMac when using it. I didn't want to have speakers and sub below me on my desk. I just accepted the ok sound. I don't use headphones...everybody is different ok? lol The new speakers system on this skinny thing is just amazing to me. I was already impressed with the 2013 but the sound was never full or have any bass. This skinny little M3 really does put out some nice sound.
