Solids, then liquids, and lastly gasses.
in solid state of matter
Matter. The denser the better.
An insulator prevents the transmittance of energy across a medium. Sound, through the molecules in air, can transmit sound energy across distance. Since air can conduct sound, it is not an insulator.
It come's from tree's but the type of material is Wood.
Think of a solid and there's your answer. Wood, metals, glass... Imagine putting your head on a solid, ear down, which materials would best transport the sound to you if someone tapped the same solid but a metre away? Those are the the solids that best transmit sound.

The BBC has always been keen to transmit the best possible quality sound.

the matter inside is bunched together so sound travels best through a solid.
Sound travels fastest, and best through a solid. eg. steel

This is a matter of opinion. And it depends on what you need the stereo sound system for. Do you want it for bass? For surround sound? These factors will affect your selection.
Sound travels faster and more efficiently through liquids then through gases (whales can communicate for hundreds of kilometers) Sound travels faster and more efficiently through solids then either liquids or gases (ear to a railroad track to hear an oncoming train...don't try this at home). Exotic states of matter like neutron stars may be "best" for sound.
