Headphoneus Supremus
It appears that some people here can't acknoledge that they are mistaken.Note that I do not hate this card, I actually love it but I do have to acknoledge cetain limitations such as the loss of dynamic range when dealing with low impedance high sensitivity phones. Out of all the phones I have used with it only one that had a sensitivity of 115db @1mW revealed any noise at all & that was very difficult to hear. I do acknoledge that there are more sensitive phones than these were. The ten ohm output impedance should not be much of an issue with most any phones as most amps have similar resitors built into them , even high end ones such as the Burson (5ohms) to protect against shorts.
