Markets Served

Excellence, Experience, Ingenuity & Availability

  • When you choose diamond design, you are among good company

    How do we back up our claim of excellence? We work for approximately ¼ of 1% of the world's billionaires. Some other company may be able to match or beat that but we doubt it. We routinely find ourselves in mansions, on $50mm private jets and $100mm private yachts

  • We've been a Control4 dealer and been doing smart homes and home theaters since 2008

    Nearly a decade might not sound long for most industries but in home automation and home theater we are considered veterans. Our second install was a 14,000 sq. ft. residence. We've been focusing on large projects ever since.

  • If you're getting multiple quotes across multiple platforms, here's what you're gonna hear...

    "Control4 is great for a small home but for a large residence [or yacht] such as this you need [insert competitor here]." In reality, most dealers offer multiple brands and when a project exceeds a certain size they switch to Crestron to make more profit. Accordingly, they have no experience using Control4 in large projects. We've been doing Control4 in mega-mansions since the beginning and have done some of the largest Control4 residential and marine installs worldwide (PS, it works great and our clients saved tons of money too).

  • We regularly operate in five states and have availability throughout north America 24/7

    One of the largest A/V installer companies recently went bankrupt leaving tons of customers on the hook with half-completed projects and lost deposits. We've been growing exponentially since 2008 (and have been recognized by CEPro Magazine as a Rising Star). Business couldn't be better and we aren't going anywhere except all over the US and the Caribbean performing installs and supporting our clients. We have regular support hours, after-hours and 24/7 support packages and concierge service available.
