AudiAV makes a full line of racks that are custom tailored to your needs. You contact them, give them a list of your equipment, and go over the various alternative platforms, from the basic standard plinth, all the way up to the Master Signature shelving . A two-foot-tall, two-shelf rack costs around $2,788 while a six-foot-six shelf version starts just under $5000.
This pricing mentioned is before adding on any options like Master or Signature shelves. Choose either granite or carbon fiber tops to match your design style. The shelves are highly adjustable thus making the rack adaptable to any system. You can always add new shelves or upgrade the unit you already own. Because these systems are so versatile and tough, they will be around a long time.
