Hi there!
Very nice article, it helped me understand the principles of DLNA a lot better!
I however have a question; all the media renderers mentioned here have a build in amplifier (or am I wrong here?), but I have a perfect stereo at home with an aux input so I'd rather not buy a renderer with an amplifier. Is there any media renderer that would fit in the setups mentioned above that I could plug into the aux input of my stereo?
