Granite Audio started out as a hobby 25 years ago. I was one of only two people in Arizona doing audiophile quality restorations on vintage tube amplifiers, such as McIntosh & Marantz. I was also collecting and restoring antique vacuum tube radios, specializing in the big 12 to 40-tube high-fidelity sets from the 1930's. I did audiophile type capacitor upgrades on the old radios as well.
As a professional cabinetmaker and audiophile I had been building my own speaker designs for years already. In the mid 70's two friends of mine in the disk mastering business in L.A. collaborated with me to design a studio monitor speaker. They were frustrated with the accuracy of the available monitors and needed a speaker they could rely on for their disk mastering businesses. We made several production runs of the "Kenlund Studio Monitor" and more than two decades later these monitors are all still in use by professionals from Arizona to Beverly Hills to Idaho.
In 1977 my venture became Don's Custom Cabinets. In 1983 the business grew and I incorporated as Broadway Cabinetworks, Ltd. In 1995 I decided to expand our presence in audio and take on the task of developing a complete tube system. After several years of R&D we debuted our Granite Audio system concept at Stereophile's HI-FI'98 in Los Angeles, California. Many other manufacturers had been working on using alternative speaker cabinet materials during the same time. But, we were the first to successfully bring an entire acrylic-granite integrated synergistic system to market.
I had certain design criteria in mind when I developed our product line. My main criteria was to design products that I would want to own and listen to. My products had to please me visually and musically. The amps had to be pure vacuum tube designs. I use vacuum tube rectification, amplification, and regulation. Many audiophiles are married and find themselves frustrated with trying to place the speakers and amplifiers in the optimum listening positions while their wives wanted the black boxes hidden from view to maximize their decorating tastes. I decided to build a system that would be as pleasing to the wife's sense of décor as it was to the audiophile's sense of music enjoyment. The last demand I put on my products was to use the best available parts and materials to insure long life and reliability.
