See what our long list of happy and satisfied customers have to say about us.

“Not only did David and Barrie do a great job on the design and installment of our custom entertainment system, they do not forget you as a customer. I had an issue with my A/V receiver come up. Even though it has been a couple of years since we completed our project, David was prompt with his help. He got me connected with Marantz (who by the way has excellent customer service – David only works with the best) and the system was back up and running in no time. Thanks for the great entertainment system Tecknos and thanks for always being there!”

“Tecknos did a perfect job installing my whole home music system. They overcame every obstacle that my challenging condo threw at them, and the results are beautiful sounding and easy to use.”


– Mika Sorkin

“I have worked with David and Barrie  on three separate occasions. Each time they have delivered quality work at an affordable price. Both are solutions-oriented and look to provide their customer with what he/she wants without paying a nickel more. I would recommend David and Barrie to anyone who asks!”


– Daniel Laughlin

“Dave and Barrie did an awesome job of wiring up our home audio, video, internet and cable. Meticulous attention to detail created a world class system for us.”


– William Linger

“Just awesome people! David Stollmack is just a classy person. If you have been around Charlotte awhile he ran what was Audio Video here in town. After selling out (and I am sure set himself up well for retirement) he noticed that Charlotte was missing true audio video type of gurus. He created Tecknos to provide a personal touch and, boy, do they deliver. Great prices, great equipment and they stand by their work and word. I can not tell you the compliments I get on my own setup in my home and we are not even audiophiles or anything. We just like quality equipment placed well that it actually becomes like furniture or like the TV’s that are hung, like wall art.

What can I say about David’s own technician, Barrie Clark, what a wonderful person. Generous with his time, generous with his thoughts, listens to the customer and delivers more than you can imagine. He will give advice if you are willing to take it and I would say, you need to ask. What a wealth of audio and video knowledge and he stays up on the latest and greatest.

We were so fortunate to reach out to Tecknos and partner with them on our needs. I feel blessed and have added two brothers to my own family. Tecknos is more than a business to these gentleman, it is a way to provide joy to many in their own special way. Thanks for all that you have done for me.”


– Jim Fortner

“As a long time home electronics customer of David Stollmack I can tell you that no one has the expertise and service that he and his team at Tecknos offers. Save yourself time, money, and disappointment by calling them today to handle your installations, product recommendations and home technology needs.”


– Tony Shannon

“I wanted a home theater system for my game room that would ‘wow’ my family and friends. My living room also had a cut in above the fireplace (the type that was popular before flat screens) and I did not know how to mount my 60″. The guys at Tecknos were extremely helpful. They suggested a 92″ 3D projector in the game room with surround sound. The price was more affordable than I thought it was going to be. When they got it done (within one day), I was amazed! It really does have that wow factor and the picture is very clear (even in 3D). As for the living room, they built a frame to hang the 60″ and it looks awesome! They also recommended a Sonos playbar which really fills the room. If you are looking for quality, professionalism, and creativity then I would look no further than Tecknos.”


– Dave Bowen
