The Trinnov ST2 Pro and Sonarworks are both room correction equalizers. The Trinnov ST2 comes as a piece of hardware whereas Sonarworks works on your host computer. They both are great products but the Trinnov costs about $5000 more than the Sonarworks. Why, might you ask?
In the video below I will tell you why I reluctantly spent $5K for the Trinnov ST2 Pro after 10 minutes of demoing it.
