Our San Diego mastering suite is outfitted for critical listening.

Combined with active bass trapping technology from PSI and industry-leading digital acoustic correction from Trinnov, we are able to finish records in an audiophile’s dream listening environment — a space that is pleasant, but quite revealing.

The suite also hosts a wide selection of analog mastering equipment that boasts industry-leading performance and transparency to ensure that mixes and stems are treated with the care that they deserve. With 64 analog outputs and several analog summing mixers on hand, Rose Quartz Mastering is one of the few studios in the world capable of offering analog stem mastering for up to 32 stereo stems at such a high standard of fidelity. Each analog (and digital) connection in the studio is made via Mogami Gold or Platinum. In addition to our carefully crafted analog signal chain, we have a suite of digital options in the form of plug-ins and software programs.

ABOUT SAMMY

Since 2018, Sam Kumar Tandon has worked with artists, engineers, and producers from all over the world. Having started his audio career in San Diego live music venues like Mira Mesa’s Epicentre and label-owned recording studios like Legend Records, his experience in eclectic listening environments allows him to work with all kinds of source material without sacrificing quality standards. 

Whether he is working with mixes from a two million dollar studio or a two hundred dollar bedroom, the record always receives 100% of his attention. Tandon is obsessed with creating emotional and unapologetic listening experiences that stand the test of time. When he isn’t in the studio, you will find him teaching at Gallery 130 and designing audio technology at Breakaway Dynamics

“Sam is one of the very few mastering engineers I trust to enhance the music while still doing justice to the song, leaving my mix and productions intact. The clients are given the best version of their vision. Period.”

- Richie Beretta, Mixer & Producer (Beyoncé, Major Lazer, Diplo, A$AP Ferg)

“An acute ear. It’s the most important piece of gear that a mastering engineer has at their disposal. This is what Rose Quartz brings to mastering, and it's why I continually bring them my mixes. Besides having killer gear; I know that they will take the time to listen to the music and craft a master that always exceeds my expectations."

- Rich Stine from The Byrd House in Richmond, VA
