Mount Olympia

MAstering Manifesto

We believe in enhancing records in a way that prioritizes and gives “voice” to the mixes we’re provided with. We bring art to life… send us something great!


We believe in the simple clarifying power of an impeccable-sounding outboard master chain, and we continuously refine ours to exude a striking musical purity (down to our silver point-to-point interconnects).


We believe you can absolutely tell "when fun was had” during the record-making process (yes even in the darker stuff), so we listen with an ear to ensure that these intangibles are preserved, heard, and felt for posterity.


We believe that mastering is a service industry, and that well-engineered music will scale with the size of your audience. When we've succeeded in our role as stewards of the music, each one of your punches lands as it was intended to.
