Hi there, I am reading the thread and trying to understand it nevertheless I am not a specialist - just music lover or something. Still I am very interested in the topic because at the moment I feed my DAC from a media player via SPDIF /BNC/ considering this type as the best jitterless connection. However recently I heard that SPDIF is converting and manipulating the original data two times - first in the source and after that to split it in the DAC:s SPDIF receiver. Therefore the ideal connection would be a direct data transfer from the source to the data receiving chip in the DAC. In such a case a media player with an USB output could be a high end solution ??? Sounds quiet naive but still? Please comment, Thanks.
