Marsh Mastering/The Lathe Room on SoundBetter

Marsh Mastering is a top-tier, no compromises audio boutique with an outstanding global reputation specializing in custom audio mastering for today's Vinyl and Streaming formats while supporting all digital and analog legacy mastering formats.

Situated in the Hollywood Hills of Los Angeles, Marsh Mastering's west coast studio features a purpose-built hybrid tube/discrete console, developed in-house with Steve Firlotte of Inward Connections with custom and modified processing from EAR, Maselec, A-Designs, Great River Electronics and Inward Connections. The console is capable of operating in both Left/Right and Mid/Side configurations simultaneously. Console tubes are from Wathen Audio​ and are hand-selected and then cryogenically treated for unmatched performance. All filter networks are one-of-a-kind designs from Inward. This room was updated in 2021 with a PMC Immersive array to Dolby Atmos Music '

Marsh Mastering's second Los Angeles studio is The Lathe Room. A vintage Scully 601 Disk Mastering Lathe with Pitch18 preview electronics and thoroughly updated and modified Westrex cutting electronics provide the foundation for a system of unrivaled fidelity.

With it's own custom analog mastering chain featuring EAR tube EQ, Maselec A/B program EQ's, Maselec compression & HF limiting, a custom cutting console, filtering by Inward Connections and a pair of Studer A80 tape machines with 1/4" and 1/2" configurations, 100% analog mastering tape to disk may be achieved. The entire system is supported by Scully/Westrex 'Godfather' Len Horowitz from History of Recorded Sound.
