JCAT Reference USB PCI-E card

This is the previous version of the JCAT USB card (not the Femto). I recently purchased the Femto USB card and am no longer using this one. Obviously this was amazing enough that I upgraded to the new version. Honestly, I can't really tell a difference - both cards sound amazing. I was using it with the power supply from my computer ( not with an external linear power supply) and it still made a significant improvement over regular USB. They say that using a full linear/external power supply can make it sound even better.

Obviously, your computer will need an open PCI-E slot to make this work. I don't believe Windows/Linux require any drivers ( I'm using Linux and it works great).

Let me know if there are any questions I can answer.
