The Vali 3 

The Vali 3 tube hybrid headphone amp and preamp is an improvement from the previous generation Vali 2++. Major improvements include:

• 100V on the tube plate (over 50% higher than before), rather than 60V, for increased linearity and gain
• Topological improvements that lower overall feedback and maintain performance
• A new optimized layout with better signal flow and ergonomics
• All-new attractive advanced-form USA-stamped custom chassis
• Massively improved ventilation and lower operating temperatures

• The Vali 3 is designed to be ready to tube your entire desktop—delivering plenty of power for hard-to-drive headphones, and a low noise floor for more sensitive cans. 

  In addition to its built-in headphone amp (a ¼ front panel headphone output is provided), the Vali 3 includes RCA inputs for an additional source, and preamp outputs that can be used to connect to powered speakers and speaker monitors, and home audio systems. 

  With a familiar Schiit cabinet design, the Vali 3 stacks perfectly with Modi DACs or Loki Mini equalizer.

• Tech Note: The Vali 3 ships with a 6N3P tube standard for great stock sound. However, for even better performance, users can also use the 5670/2C51, ECC42, CV4013, and the classic WE396A.
