Schiit Freya MKI Tube Balanced Preamplifier with Remote [2nd hand]

Schiit Freya MKI Tube Balanced Preamplifier with Remote [2nd hand]

Reference:

Condition:

pre-owned

Used unit, in excellent condition, slight stain on the chassis, very small signs of use. Includes original packaging, remote control, accessories, and 1-year warranty.

6N8S Tube Version.

Freya is a true high-end, balanced, remote-control preamp. Switch between passive, differential buffer, and differential tube gain modes, and enjoy the fine control of a 128-step relay-switched stepped attenuator volume control with perfect channel matching.

Whisper-Silent Tube Stage—With Tube Shutdown

Now, you can enjoy a tube preamp without the hiss and hum of classic designs. Freya+ offers super-quiet tube modes with DC heaters and semi-circlotron, noise-cancelling output stages. Better yet, the tubes turn off when you’re not using them! That’s right, both the tube heater and high voltage rails go away when not in use, so you can preserve lifetime of costly tubes.

Forkbeard™: Total Control is Just the Start
Freya+ F includes Forkbeard, the only multi-product, multi-stack, unified control system. One iOS app gives you total control of Freya (and many other Schiit devices). Don’t want Forkbeard? Drop it off your order and save $50. You’ll still get the standard IR remote control.

The Ultimate Volume Control

The benefits of a relay-switched stepped attenuator for volume are clear. Compared to a potentiometer, they give you essentially perfect channel matching and near-unmeasurable distortion. However, some preamps with relay-stepped attenuators confuse you with buttons and screens. Not Freya+. Freya+ has a volume knob that works just like a volume knob—just grab and turn.

Designed and Built in the USA

By “designed and built in the USA" this is what we mean: the vast majority of the total production cost of Freya+ F—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis, transformers, PCBs, and assembly are all from California, and all Freyas come together in our San Antonio, Texas production facility.

SPECS THAT MATTER

Noise: inaudible
Distortion: unmeasurable by APx555 in passive mode, better than any transducer even in tube mode
Heat: gets quite warm; not surprising for a tube-based, Class A device

Size: shelf- and rack-friendly, not super desk-friendly
