I recently bought a Thunderbolt Display and the sound is really good, but I'm wondering whether the sound from external speakers would be noticeably different. The only difference I hear between the Thunderbolt speakers and my Beats Studio headphones is more depth in the bass from the headphones. The Thunderbolt Display sounds more clearer though (it's a bit difficult to explain). Would I get significantly better sound from external speakers? And what speakers would you guys recommend?
