Hi Stephen,

Thanks for that cheerful explanation. Actually I did have those doubts in my mind earlier, but there is another thing which i think can come over this problem. As i mentioned earlier that the router has OpenWRT firmware installed on it, so can i not write my own Digital To Analog Converter (If this is wat you mean by "no analog connection to the CAT5 Cable.)?

Or probably, pass on the digital data to an external hardware DAC, which can then pass it on to the speaker.
