“Easy setup. Totally stable. Now I can trust my headphone mixes. I love the simulations as well for getting a feel for my mix on other systems.”
 Aaron Russell
“I've poured lots of money and time into my love of music in the last 15 years. If I lost everything and had to start again getting Sonarworks Reference and a pair of calibrated headphones would be one of the first three things I’d do.”
