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
