Wifi Audio Streaming adapters

Hi there.

I would like to know if any members have had experience with Streaming Audio from a mobile device to a standalone Audio Amplifier via Wifi (not bluetooth).

I have done some research and have found a few devices - but havent been able to read any specific reviews.

All I would like to achieve is similar to how I currently use my logitech bluetooth adapter but via Wifi for increased range and overall bitrate audio quality.

Anyone care to comment ?

Cheers

Ren
