receive music via bluetooth from mb

is this possible, or somthing already like it? I'm new to apple and wireless technology,

mac )))bluetooth))) receiver --audiojack--> Stereo

edit: I'm dumb, after randomly browsing apple.com I realized AirPort Express Base Station with AirTunes supports exactly what I need, sorry mods

FYI,...

Airport Express supports optical audio. Do yourself a favor and get a toslink to mini toslink cable if your receiver support optical audio. Most new ones do.
