About Eardrum Audio

Eardrum Audio is a family-run specialty hi-fi retailer built on a simple idea: great sound comes from systems that are thoughtfully chosen and well matched to the space they live in.

The company was founded by Mark Gringer, who spent more than 25 years in custom audio and home theater installation, including running Audio Services in New York. After relocating to Delray Beach, Florida, Mark founded Eardrum Audio to focus exclusively on high-performance audio and thoughtfully integrated modern systems.

More recently, Mark brought on his son Phil to lead the digital, marketing, and e-commerce side of the business. Together, they represent Eardrum at major industry events like AXPONA, connecting directly with manufacturers and customers.

What We Do

We work with a carefully selected group of manufacturers whose products we know well and trust—chosen for design, performance, reliability, and how well they fit into complete systems.

Eardrum Audio is an authorized dealer for every brand we carry. All products are new, fully warrantied, and sourced through official manufacturer or distributor channels.

We work directly with customers by phone, email, or in person, offering guidance on system matching, placement, setup, and upgrades. For select systems, we also offer custom delivery, installation, and in-home setup, helping make sure everything is properly positioned, connected, and performing as it should.

Private Listening

For customers who would like to hear equipment before making a decision, we offer private, by-appointment listening sessions for select products and systems. These sessions give us the opportunity to spend time with you, understand what you're looking for, and offer in-person guidance without the pressure or distractions of a traditional showroom.

Built Around the Music

Whether you're refining an existing system or putting together something new, our goal is simple: to help you enjoy your music more.

If you ever have questions, we're happy to help.
