Description

Ever wanted an ultra-high-end speaker amp—in a compact size perfect for desktops and smaller rooms? Have you wished for a dead-silent, no-hiss amp for nearfield listening—that’s still capable of driving most speakers to lease-breaking levels? Wish no more. Welcome to Gjallarhorn.

Less Power, More Better
There are plenty of big-number amps out there, but how much of that do you really use? How loud before the neighbors complain? How old does the constant hiss of a high-gain get with the speakers a few feet away? Gjallarhorn was designed to deliver exceptional performance, without the downsides. Or, as we put it: less power, more better.

Exotic, Fully Discrete Topology
Gjallarhorn may be smaller than our other amps, but that doesn’t mean it skimps on quality. It features an exotic, fully discrete, current feedback gain stage with our exclusive Continuity S™ output stage, as well as a fully linear power supply—including a toroidal transformer with stacked rails and 30,000uF of filter capacitance. No Class D, no switching supplies, no fans. Pick it up—it’s a heavyweight!

Flexible for Desktop and Beyond
Combine Gjallarhorn with any of our headphone amps to add power for nearfield monitors, or pair with Saga for an exceptional small-room system. Have balanced preamp outputs? You can use them with a pair of Gjallarhorns, for additional power and capability.

Designed and Built in California—For Real
By “designed and built in California” this is what we mean: the vast majority of the total production cost of Gjallarhorn—chassis, boards, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our California factory. Our PCBs are done in Simi Valley. You get the picture.

5-Year Warranty and Easy Return Policy
Gjallarhorn is covered by a 5-year limited warranty that covers parts. And if you don’t like your Gjallarhorn, you can send it back for a refund, within 14 days of receiving it.
