Lore Headphone Amplifier

$15,500.00 USD

The Lore is our storied vacuum tube headphone amplifier, long regarded for its musicality, craftsmanship, and timeless design. Doubling as a low-power speaker amplifier, it brings exceptional flexibility to any listening space. Inspired by classic tube designs of the 1950s through the 1970s, each amplifier is meticulously hand-wired using premium components, an external power supply, military-grade switches for lasting reliability and exceptional performance.

Rooted in classic tube topology and refined through decades of listening, Lore delivers warmth, depth, and presence in equal measure. Handcrafted with premium components and carefully selected tubes, it offers a sound that feels alive, personal, and deeply connected to the artist.

Note: The Dual-Mono power supply includes a JLP-07 power cord. The Solid-State Power Supply does not include 5AR4 or OC3 P.S. tubes. If you have any questions about choosing a power supply, we're happy to help.
