Who We Are

At CSA we’ve been selling, installing and servicing high-end audio for over 30 years.

Owner Ralph Fonte and Partner Mike O’Keefe take great pride in the brands they select, the rooms they design and the installation work done by their crews.

Ninety percent of our customers come from referrals from other satisfied customers. We’ve been happy to handle projects from all over New Jersey, New York, Connecticut, and even as far as Florida and Maine. When one of our customers buys a new house, we’re pleased to be one of their first calls to design another exciting Home Theater or Whole-House Sound or Automation system.

We’re authorized dealers for all of the brands we sell, which is important because it means that you’re buying from someone who understands what they’re selling, knows how to set it up and service it, and that you’ll be fully covered in the event that you ever need warranty service.

After more than 30 years in our original location, we decided to build a multi-story facility in Upper Montclair where we have 4 customized showrooms to demonstrate all the greatest audio and video equipment. Auditioning in this environment will give you a clear sense of what the gear will sound like in your home. For many of the brands we carry, our facility is the only place in NY or NJ where you can see and hear these award winning lines.

At the end of the day what separates CSA from either the “big box” stores or other high-end stores is our people. We really do love music and movies, and we really enjoy helping our clients realize their dreams. Please contact us today whether you’re upgrading a single component or planning a new Home Theater.
