Mark Levinson & PARASOUND—Serviced with Precision
Boutique, component-level service for reference-class audio electronics—where correct diagnosis, careful correction, and verification-grade testing.
Mark Levinson Service
Mark Levinson systems deserve a bench that treats precision like a craft. We diagnose at the circuit level, correct the root cause—not the symptom—and validate performance with controlled, repeatable testing before your unit returns home.
Component-level fault isolation for intermittent and protection-related events
Power supply, output stage, and thermal behavior verified under controlled conditions
Documented QC checks for confidence beyond “it powers on”
PARASOUND Service
PARASOUND JC & Halo designs are engineered to a standard—service should be too. Our workflow focuses on stability, correct bias behavior, authentic parts, which are only obtainable by us, and verification that the amplifier is ready for long-term duty.
Output stage and bias network correction with stability verification
Protection / relay behavior tested for consistency and reliability under heavy load
Verification-grade testing before return shipment
The Tone Garage sits at the intersection of brand trust and designer intent. As Mark Levinson’s Western Regional Service Center and Parasound’s Flagship Service Center we work inside John Curl’s designs every day.
John Curl helped shape early Mark Levinson circuits and later created Parasound’s celebrated JC Series. The “JC” in those model numbers refers directly to John Curl — and amps with that designation are exactly what we’re built to service.
At The Tone Garage, we specialize in the art of high-end audio service, repair, and restoration. As the Western Regional Service Center for Mark Levinson, JBL Synthesis, ARCAM, and Crown, we are trusted by both manufacturers and discerning owners to deliver world-class care for the finest audio systems. With four decades of hands-on experience, our technicians combine deep technical expertise with a passion for preserving sonic excellence. From the legendary warmth of McIntosh to the precision of Mark Levinson, every unit is treated with meticulous attention to detail. Most parts are kept in stock, and for many models, repairs are performed within 48 hours—because luxury audio deserves premium service without delay. Whether you need warranty work, routine maintenance, or complete restoration, The Tone Garage is your trusted partner in keeping your system performing at its absolute best. At The Tone Garage, it’s not just repair—it’s the preservation of music at its highest level.
