Schiit USB Upgrade Board

Schiit USB 2.0, 24/192, Async, Completely Buzzword Compliant

Have high-res music? No problem.

Featuring a high-speed USB 2.0 interface (not 1.1) and asynchronous data transfer to 24/192, based on the C-Media CM6631 USB receiver.

Schiit Scheduling System Reduces Upgrade Time can install the USB board for you, with a convenient scheduling system that allows you to keep your Schiit Bifrost or Schiit Gungnir until we are ready to turn it around immediately. Just place your order, and follow the steps in the series of emails. You will be notified when your order is accepted, when to send in your DAC, when the work is performed, and when it's shipped back to you, for complete transparency.

Installation Options. If you are an experienced electronics technician or engineer who is familiar with ESD precautions, or work with a good tech, you can choose to have the USB board sent to you directly, fully tested and protected in an antistatic bag.

Please note that purchasing this, you are saying, "Yes, I am, or know, a competent electronics technician who does not need hand-holding for this installation, and I will not allow an inexperienced person to perform the upgrade, since I understand there are no user-serviceable parts inside."

No drivers are required for Macs, and Windows drivers are downloadable for Windows 7, Vista, and XP.

We cannot provide tech support to linux users as we have no knowledge about this operating system.
