We were having difficulty with our surround sound system and Field Mead at Hi-Tech worked with us for two days to make sure that we found a solution. He researched the cabling required by Directv (our new cable provider), and suggested a cheaper, more correct cable than what we had purchased at our local big box store. After we successfully installed the cable the next day, we were pleasantly surprised when Field called back at the end of the business day to make sure we had surround sound! We always call Hi-Tech with our audio questions.
