Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
When anyone auditions my setup they don't leave the same way they walked in. The funny thing is that size does matter because they see and hear everything and they think it's great, which at one time it was... but now the TV (a 61 inch Sammy DLP) is 5 years old and 720p and only 1,000:1 contrast... obsolete by today's specs, but that audio never chnages... that SVS subwoofer will punch you in the chest just like it did 5 years ago and will continue to punch people in the chest 5 years from now regardless how much the video changes.
You simply can't beat big speakers with big magnets producing clean big clear solid sound... Bose and those little cubes... paw-leeze!!!
I have a funny story about that, a guy I know has a Bose Acousticmass system and he came here and left in tears. Sound waves are sound waves and the physics of them can't be chnaged... you can try to fool your ears, but you ears will tell you you're the fool when you hear an audio system with big towers allowing the frequencies to be produced the way they were produced when the tracks were created in the first place. I personally consider the audio and the video on the same level and all rolled into the High Definition bundle. There is a difference between Surround Sound and Home Theater audio. The Bose Acousticmass systems are surround sound systems, but they are not even remotely Home Theater capable.
You mention $3K for audio gear... sounds reasonable to me. I just did some quick math on my stuff... speakers alone $5,000... receiver Yamaha RX-V2400 $1,100. You know, that would be a good poll question... how much for the gear we all have... one for audio then one for video or one for just the whole damn setup.
