Marantz employs product designers and engineers with over 30 years of know-how and experience. They perform over 50 different quality validation and assurance tests for every piece that ships with the Marantz name on it. Every Marantz takes years of up-front design detailing, sound obsessing, and experience validation before they deliver a single unit to you. And they continue testing throughout the product’s life. Everything they know and everything they do is intended to make your Marantz ownership better. That’s the real value of 70 years.
