Welcome to Precision Audio Laboratories!
We Are Sorry But We Are No Longer Accepting Shipped In Gear for Repair
Precision Audio Labs is one of North America's last Precision Vintage and High-End audio service centers. Our Techs are Factory-Trained and have more than 40+ years of experience working on brands like Audio Research, Kenwood, Pioneer, Marantz, McIntosh, Sansui, and many more!

Over the last 30 years, high-end audio service centers have become almost extinct. Most High-End audio techncians who are well-versed in transistor and vacuum tube audio equipment have retired or moved-on to the great Ampitheater in the Sky. We are very proud to be able to offer these skills to those of you who love your audio equipment as much as we love restoring your gear to factory-perfection!

The most important decision in finding the Right Service Center is to find experienced, knowledgable, and trustworthy technicians who will give the very best care to your audio equipment. If you need a repair or you are looking for a total restoration, to include LED panel-lamp upgrades, we can help you get there! Please scroll down and enjoy some of our favorite stereo brands and models that we restore every day. Thank you for visiting Precision Audio Labs!
