Audiophile gear repaired down to the component.
Amps, DACs, turntables, receivers, tube gear, vintage and modern. We diagnose to the component and quote a flat rate before any work starts.
Make it sound better than it ever did.
Beyond repairs. Pick a direction and we'll quote it properly.
Full Recap / Cap Upgrade
Quality electrolytics and film caps tighten bass, open up detail, and restore a tired amp, receiver, or crossover to spec, often better than new.
Tube Rolling & Tube Upgrades
NOS and premium output and driver tubes. We match, bias, and burn in, so you get the tone you've been chasing.
Crossover Rebuilds
Fresh film caps and air-core inductors in your speakers. Owners describe a crossover rebuild as getting a new pair of speakers.
Bias & Precision Setup
Factory-spec bias, DC-offset correction, and calibration. The cheapest upgrade you can buy, and most gear has never had one.
Turntable Upgrades
Cartridge upgrades and setup, tonearms, platters, bearings, and motor and PSU work. Table upgrades compound, so we'll plan the order.
Headphone Mods
Detachable-cable conversions, balanced re-cable, earpad and damping upgrades. Breathe new life into cans you love.
Power Supply Upgrades
Regulation, snubbing, and beefier rails on amps and DACs. The quietest, most dramatic upgrade in audio.
Vintage Modernization
LED dial lamps, Bluetooth and streaming inputs, safety upgrades. Keep the classic look and make it a daily driver again.
