After purchasing a digital cable receiver with an optical digital sound output, I have found that all optical inputs are assigned to my AV receiver. So that optical cables must somehow be connected to the coax input. First, I ordered the conversion of TA Multimedia. This is, however, how now only results from the updated after my complaint item description, only able to stereo signals optically convert into electric. Not exactly the best, if you want home cinema sound. So I ordered the much higher priced converter of Oehlbach. He points to the metal housing in a very good workmanship. The signals are converted perfectly and without the feared of me time delay and output to the amplifier. The purchase is worthwhile in any case insufficient number of optical inputs !!
