All I can say is this is exactly what you expect from a business. Knowledge and the capability to execute. I thought I could have done my sound system on my own but I'm so glad I hired John instead I'm not so foolish after all. I'm absolutely grateful to have had this project go so seamlessly. read more

John Dewey and HPAV is the best Audio/Video company I've ever worked with. After decades with another AV company, I switched to HPAV . Why? Because John's knowledge, dependability and access are second to none. He's provided me with quality work and products and is on top of all technology industry trends. His calm, patient demeanor makes him a pleasure to work with. I give John and HPAV an 11out of 10 and unequivocally recommend him for any AV needs!! read more

I had the opportunity to visit a friend who had just had High Performance AV complete his A/V system throughout his home and office. While visiting, John, the owner of High Performance AV happened to stop by to check on things and was able to give me a walk-through. I was extremely impressed, not only with the high quality of the equipment and workmanship that was used and the incredible sound that the system produced, but also with John's the level of customer care and follow-up. As a someone who is very involved with high-end residential renovations, I will recommend High Performance AV without reservation to all my clients and friends! I urge you to contact High Performance AV if you are in the market for an amazing Wi-Fi and audio network system. You will be incredibly happy you did!! read more

John at High Performance AV was great to work with in replacing 2 TVs, a receiver, a subwoofer and setting up satellite WiFi throughout our house. He was very responsive and knowledgeable about what products work the best for our needs. We will have him back again for another project in 2025. He came highly recommended from our builder. read more

I've known John for many years professionally. I'm a rep and originally met John when he was working for Century Stereo in San Jose. At that time Century was one of the top AV dealers in the country. John then went on to start his own company- HPAV. I bought a new OLED TV and needed someone to calibrate it. I contacted John and he suggested that I use the TV for a while prior to calibration to make sure the display was properly "broken in". He then called me back to set up a time. He showed up early and worked diligently for 6 hours making sure the display was as good as it could be. Words that come to mind of his service and work ethic- professional, patient, and extremely qualified. I read a review from a "jack m." and I have no idea who he is talking about. It surely is NOT John Dewey. I've dealt with hundreds of AV companies over my 50 year career and HPAV is in the top, small group. read more

Really great experience with John and High Performance. We had a pretty extensive landscape overhaul in our backyard and he did a Sonoscape system for us with 3 zones. Everything was done on time, he made sure everything worked, he's stopped back over when a landscaper subsequently cut a line by accident, debugged an issue with a fan on of the amps, etc - couldn't be more happy with customer service, quality of work, quality of products he sells. If we ever wind up moving, I'm having John in right away for a similar system. One other thing to note: we wanted an in-house network for wifi. He came over and evaluated what we needed and wound up recommending a simple amplification device that I could do myself. We were already happy with the work before, but that really scored high on the trust side for me. read more

I got a quote from John Dewey (the owner) sent him a check and he promptly quit after getting the money and cashing the check. This is what happened: I began to ask him about the job and why it costs so much. $6000 for upgrading access points (AP) to a newer AP and being a tech guy I was suspicious of his answer. I saw the AP online for $199 so it occurred to me that he was gouging me. But I knew this going into it because people told me he overcharges and tries to see what he can get away with. He's quite simply the most expensive technician I've ever worked with. Left me hanging after engaging with me. Too bad for him, it could have been months of business for him if he were more honest. I still don't have my money back. Don't know why he's so peculiar. read more

I used HPAV to install my TV and other peripheral equipment. The TV is flat mounted in the wall with a swing arm for multiple viewing positions and the rest of the equipment is set up in a custom cabinet. John did a great job, it's a very solid installation and looks beautiful. But the reason I'm really recommending HPAV is that the customer service was above and beyond. John answered the thousand questions I had very patiently and helped me narrow my design down to what would work best for me. Also the folks who owned my home prior tore the wall up removing their av equipment. John and his crew took extra care to make the wall all around the new install look new. They did a GREAT job and I felt really taken care of. read more

I highly recommend High Performance AV! My husband and I were at our wits end regarding the installation of sound in our home. Not being very tech savvy, we had no idea where to begin! After one exorbitantly high quote from a local business and lots of frustration (the wifi in our home was too weak for wireless sound, we were told) in walked John, from High Performance AV, and saved the day! John, a referral from a friend, is an absolute master of his craft! Not only is he a technology genius and highly professional person but he also has a wonderful demeanor and offers superb customer service! Everything seemed effortless from the moment I called John! The initial consultation at our home proved to be most educational and informative. John patiently listened to our needs, asked what our budget was and clearly explained what he could do for us. Within 2 days we were emailed a quote, stating exactly what we had agreed to and less than 2 weeks later the audio installation took place! Not only did John install our SONOs system, but he also resolved our wifi issues! He never tried to oversell us on anything, explained how adding more rooms/speakers at a later stage could easily occur and kindly took the time to teach us how to work our new audio system. Thank you, John! We love the new sound in our home and are forever grateful for your exceptional service! We will definitely be telling everyone about you and calling you back when we are ready to expand our system to other areas of our home and property. read more
