Symphony Integrated Systems, LLC was the original company founded by Bradley Zimring during his second and final year at USC earning his MBA (2009-2010). From 2011 to 2019, SIS operated under the name Audio High during an 8 year partnership with Michael Silver, who in 1997 founded and ran one of the top home automation companies in the United States out of Mountain View, California.

Symphony sources the best in class in each home-automation category, and part of our due diligence to our customers is to constantly monitor the consumer electronics market to make sure our product selections remain the best in class.

In 2017 Symphony expanded to offer a curated collection of the lower cost DIY home-automation electronics after experimenting in their own homes and personally testing all of the latest offerings from Google/Nest, Ring, Sonos and various other smart-home electronics manufacturers. The home-automation market has matured to where there are high-performing low-cost solutions in each and every category of technologies that can perfectly perform in small and medium sized residences. This is a market under-served by big box retailers, boutique high-end home automation companies and independent low-voltage contractors.

While many of these products are not scale-able for a custom home of 10,000 to 60,000 square feet, they work perfectly well in all the Symphony principal’s and employee’s own residences. Our expertise in delivering simple to use and fully functional smart-home systems in houses from 2,000 to 60,000 square feet over the past 20 years has given us a vast wealth of intellectual property in designing, installing, programming, and servicing our client’s homes, and we hope to apply this to a broader market with Symphony. Simply put, when our friends and family ask us for the least expensive way to upgrade their home with the simplest and best technologies, our answer would be symphoyintegrated.com.
