It’s Your Choice: Passive, JFET Buffer, or Tube Gain
Go ahead. Run Freya in passive mode for a convenient remote-controlled passive preamp that’s ideal for many systems. If you need to drive long cables, you can simply select the JFET buffer stage, or choose the tube gain stage—a serious gain stage running on 300V rails. 
 
128-Step Relay Attenuator
Most preamps—passive or active—use a potentiometer for volume control. Freya uses a sophisticated microprocessor-controlled relay-stepped attenuator for perfect channel matching and zero distortion—and with 128 steps for ultra-precise level control. You can hear it clicking as you turn the volume up and down.
 
Yes, Remote Control Included
When you’re talking about gear that doesn’t sit on your desktop (like our headphone amps), you need the convenience of remote control for volume, input switching, output switching, and muting. Freya includes a custom remote control, standard.
 
Perfect Companion to Our DACs
Want a remote-controlled system to interface your digital gear with the rest of your system? Stack Freya and Gungnir Multibit or Freya and Yggdrasil (or any other of our DACs) for a true no-compromise remote-controlled system.
