My design, using 2.4GHz digital AUDIO wireless modules, the working distance of 328 feet, 3 Li-ion battery. And converted into a negative 12V. JFET + MOSFET amplifier. DAC with WM8740. Test results:
1.THD at 5 V peak: 0.005%(300ohm load 1kHz)
2.S/N : >86dB
Pls comment, thank !

Yes, However, this RF module is purchased. in 2006, I designed 915MHz, working distance of approximately 100 feet.
You kidding? This looks awesome!
I only wish there was more stuff flike this around, they're as rare as hens teeth.
Preferably with better quality analogue-out and a built-in DSP for remixing Dolby formats & the like (using HRTF or better) into a format that sounds realistic when outputted to stereo headphones!
The only other notable one around is that 'kleer-based' adapter from SleekAudio. But it doesn't have a DSP, it's DAC aint that special, & they lock you into their freakin headphones! Grrrr
pcomliu modify yours to do what I suggested above & I guarantee it'll sell like mad. The market's crying out for it! Don't compromise on quality and people will knock your door down!

Yeah it is a little steep...
But if you look at the actual specs, what it does, and considering the available competition, then I guess its not that bad.
Still I wouldn't pay that much without:
_________
Transmitter
*********
1) Takes optical-in
2) Transmits via 802.11G (or some proprietary cousin)
_______
Receiver
*******
1) Has a DSP which can remix Dolby content (or similar) using HRTF (or similar) into a format that makes it sound like proper positional audio when outputted to stereo.
2) Has a high quality DAC for stereo-out ...
3) Has a standard headphone jack
4) Is powered by an easily rechargeable Li-On battery.
5) Is compact & provides some means to make it mountable in creative ways.

Yes if you create the following I will buy immediately! 
There is nothing on the market, NOTHING

Yes if you design & build this I will buy it immediately!
Currently there is nothing like it in the market, "NOTHING".

...and can take out your entire house's Wi-Fi if not done properly, as Creative has demostrated with their Xmod Wireless.
