Finally a solution for all digital audio formats. Have the Fiio D07 ordered around my Philips TV to my purely analog hi-fi amplifier to connect. because of Philips only has a digital audio output, a solution had to her in the form of a D / A converter. After a long search finally found these here, in which each device must not be converted to PCM Stereo thus can be heard. This is possible but not necessarily for each device. Thanks to the Fiio D07 also no longer necessary, but it converts all formats such as. Dolby 5.1 or DTS. Remains should also be mentioned which can persuade the sound quality. An audible difference to the analog Blue-Ray player output was clearly audible. Clearer and cleaner bass voices. Now just need a connection for BD player, TV and D-Box on the amplifier, the digital of the TV over this great converter! Full 5 star deserves high, especially at this price.
