The DECO is more than a tube amp. It's an original Art Deco sculpture and Granite Audio's new flagship power amp. Each one is handmade to order by the original artist, Don Hoglund. The DECO is not a production amplifier and it takes 90 days to craft one for you in your choice of stunning acrylic-granite hues. Even the rectifier tube base is custom made by Granite Audio to match the granite sculpture.
