I don't quite get this. If you're an audiophile, you wouldn't use Bluetooth audio as it sounds awful.

Airport express with airplay that uses apple lossless with an optical initial output on the other hand is wireless and lossless

mmm, well iv done some research and found that the new APTX is lossless and uncompressed, cd quality sound as long as both devices support it. So this new APTX technology will deliver very good CD quality sound, unlike the old bluetooth technology... I own a HTC APTX bluetooth adapter which I connect to my HTC one phone in my car, and found it to be CD quality sound, unlike the previous logitech bluetooth receiver which was awful!

Bluetooth has come a long way, it has to be said. If you shop carefully enough, you can find it can be used as a great wireless audio solution, but the latest technologies are under-supported IMO.

just received mine and connected to my soundbar via optical cable. i an no expert but it's fantastic. i don't know if there is loss or anything but it's way better than what i expected.

hello cRuNcHiE, for a novice, how do you do this? how much does your setup cost? any difference to what you've proposed and Bluetooth via NFC?

Cheers

AirPlay uses wifi, you can get speakers with it built in or get the airport express adapter which is a wifi AP with digital audio out.
Costs about the same or get a refurb for £59.
Wifi has further range ( I plug one in the garden in the summer when having BBQ and stream music from my PC)
Airplay supports playing from one source to multiple destinations with different volumes.
Works with any PC/mac using iTunes or with iPhones/iPads or android with an app .
Supports wave, apple lossless and AAC audio.
The airport adapter as a combo optical output and 3.5mm analogue output.


This adapter uses Bluetooth.
Bluetooth generally is not lossless (a2Dp sounds awful)
Apt-x is the newer Bluetooth codec which is meant to be lossless Except after reading up on it, it's not and the quality will depend on the signal quality.

Basically the codec moves to a lossy mode when the audio can't be compressed enough to fit the Bluetooth bandwidth.
Apt-x is compressed 'cd quality' very debatable. A lot of people used to says 128k mp3 was cd quality but it wasn't.
aptx-lossless is 'near lossless' but I think your device will need to say it specifically supports the 'lossless' codec
Bluetooth is one source to one destination
To use APTx, your hardware must support it ( desktop pcs probably won't have it) , my laptop doesn't , neither does my iphone/iPad.


This appears to a list of devices that does support it jessebandersen.com/201…tml

Wow cRuNcHiE, nice explanation - thanks for that! Great setup you have there. Multiple sources all wireless in the garden in summertime sounds amazing. Think you've given me a new project for the weekends after the xbmc box is done. Many thanks for the idea!

Inateck do a relatively inexpensive bluetooth 4.0, apt-X compatible mini-dongle for £8.99. It gets decent reviews and they seem to have excellent customer service:

It seems like apt-X is a big step up from normal bluetooth transmission, although I do find the marketing speak around it to be fairly frustrating!
