Highlights

Classic Tube Topology: The Lore features a fully analog, tube-driven design utilizing matched NOS 25L6 output tubes in a push-pull configuration, driven by premium 12AU7 tubes. The circuit is carefully voiced to combine the richness and natural tone of classic tube amplifiers with the resolution, dynamics, and transparency expected from today's finest audio equipment.

Flexible Power Supply Options: Choose between a precision discrete solid-state power supply or an upgraded dual-mono tube power supply featuring dual 5AR4 tube rectification and dual OC3/VR105 tube regulation for maximum performance and channel separation.

TRULY UNIQUE PRODUCT

LORE is a tube-based analog headphone amplifier. It is powered by two pairs of 50L6 or 25L6 tubes in push-pull mode driven by one pair of 12AU7s. All tubes are sourced by Coffman Audio Labs© N.O.S. and matched for each amplifier.

LORE standard external power supply is solid-state.

LORE has an upgrade option for a dual mono (2) 5AR4 tube rectified (2) OC3 / VR105 voltage-regulated power supply— thus allowing for the best possible sound. This upgrade includes a JenaLabs© 716 Power Cord and high-quality fuses (2) 1 spare.

LORE is hand-assembled entirely in the U.S.A. at Coffman Audio Labs.

LORE is electrically rugged and meant to last.

LORE chassis is 100% machined (not stamped metal) and can take abuse.

LORE chassis parts are interlocked in specially designed machined slots so that only four bolts per side are required to keep the structure intact.

LORE external casework, knobs, footers, base rings, and tube shields are locally machined only for our products.

LORE internal wiring for the audio signal is high-quality 18AWG and 22AWG UltraWire© directly from JenaLabs©.

LORE has high-quality Cardas© Binding Posts, Neutrik© RCA and XLR4 connectors, and Military N.O.S. Switches.

LORE components include Vishay©, Belton©, Russain N.O.S. P.I.O. Capacitors, and custom-designed transformers specifically for our products.

LORE contact points are mechanical as well as electrical.

LORE is entirely point-to-point wired with high-quality Cardas© solder and phenolic terminal strips— it should last decades.

Operation

Coffman Labs' LORE uses a 12AU7 tube gain stage to drive a pair of 50L6 or 25L6 tubes in push-pull mode (The serial number on the back will indicate which tube type is used). This provides more power than is needed for almost all headphones and can easily drive high-efficiency speakers with 2 watts. Four separate output impedances are provided to match listening equipment, including speakers @ 8 ohms, standard headphones and In-Ear Monitors @ 8-32 ohms, and high-impedance headphones @ 128-600 ohms.
