Schiit Jotunheim or Lyr3 Upgrade board

Upgrade your Schiit Jotunheim or Lyr3 to a 4490 balanced USB card

This balanced DAC adds a USB digital input to your DAC-less Jotunheim or Lyr 3. It uses dual AKM AK4490 Verita® D/A converters, in a hardware-balanced configuration with active filtering. 

Schiit EU Scheduling System Reduces Upgrade Time

Schiit EU can install the Jotunheim or Lyr3  4490 Analog board for you, with a convenient scheduling system that allows you to keep your unit 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 unit, when the work is performed, and when it is shipped back to you, for complete transparency. 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 Dac board sent to you directly, fully tested and protected in an antistatic bag.

Other Installation Options (self Installation *note)

Please note that by selecting this option, 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."
