Astell&Kern XB10 Bluetooth amp opinions and possible group buy.

[croak]

So I somehow think a quality mobile blue tooth amp puck thing could be useful. 
However, shipping just one from (mass)drop would just be silly. 

Anyone have any thoughts or opinion on this unit?

Anyone keen on getting one and sharing shipping costs?

Drop price is 50 dollars.  Can?t be heavy even packed as product is only 23 Grammes so I suspect at least 5 if not 10 will be a half kg of global shopper shipping.

Drop closes in 3 days. 

The Blurb:

WIRELESS FREEDOM WITH APTX HD
We?d all like to improve the sound quality coming from our smartphones, but with traditional portable DAC/amps come additional cables that get in the way. Not so with the Astell&Kern XB10: a small circular device that wirelessly transmits audio data from your smartphone via Bluetooth. This DAC/amp supports the Qualcomm aptX HD Bluetooth codec, allowing for high-resolution 24-bit/48-kHz audio that?s faithful to the original file. Compatible with Android, iOS, and many other Bluetooth devices, the XB10 boasts both a standard 3.5-millimeter output and a balanced 2.5-millimeter TRRS output. It's especially great for newer iPhones without a 3.5-millimeter jack, as it can bypass the need for a dongle. It has a built-in microphone for hands-free calls, and comes with a clip for convenient attachment to your clothing.

DRIVING HIGH-IMPEDANCE HEADPHONES
Rather than simply amplifying the audio signal, the amplifier was designed with a "driving" concept to amplify weak signals and power difficult-to-drive high-impedance headphones. A strong signal is required to drive headphones with a high impedance. The XB10?s analog amplifier is more than capable of handling the task.
