I am making this query on behalf of a friend who wants to output lossless rips digitally from his computer to the dac of a Cambridge audio 740c. He has read that many soundcards interfere with the audio before it goes through the digital out and can often impose some degree of compression. He doesn't find this acceptable in the hifi domain. Is this the case with soundcards? He has been pointed in the direction of the musical fidelity v link which apparently sends an unmolested output via usb. Would thus be a superior option for his use? Any advice on this would be much appreciated. Many thanks
