TransTechnology presents a transmitter/2.1 set combo (APX-300 and SP-100) that is DLNA compliant. Nothing special to mention about the 2.1 set SP-100, so let’s have a look at the APX-300. It’s a wireless (b/g) enabled box that connects to your network and can read all audio formats that are available on the network (on a NAs, another PC, …). This small APX-300 goes even a step further and once a software is installed on a PC, it can help you decode audio formats that might not be supported. Natively, it does play back MP3/WMA9/AAC/Real Audio/OggVorbis/PCM… files already.
