Reference Series Audio Racks
These ultra-high quality audio racks represent the "best of the best" and are an upward design progression based on our highly successful 45-Series racks.
These racks are hand crafted using only premium-grade materials and are computer modeled and stress analyzed for superior performance. Incorporating an extensive amount of custom-machined and fabricated components, the manufacturing cost is somewhat higher than our other product lines, although the performance exceeds that of competitive racks costing much more. Made in the USA!
Price $1100.00 .. Special offer $1050.00 (as shown, with 12 x 24 cherry-trimmed platform)

The aspect ratio of this audio rack is designed for use with larger "tower" style power amps, like the Theta Citadel or Mark Levinson No53 but is also perfect for any traditional style monoblocks amplifiers. Includes 12 x 24 inch platform. Available with platforms trimmed in solid cherry or black ash.
The unique X-frame design, borrowed from our classic 45-Series, provides exceptional strength while maintaining a clean, "open air" appearance. The resistance to torsional flexing far exceeds that of most other frame designs. The massive proportions of the cross-beams and columns are simply "pure overkill".
A matching audio rack, the Zero GXT is also available.

Our famous Multi-Element Granite Platforms:
The approach is simple and well executed. With just three basic material layers it is easy for us to optimize the performance and eliminate the "muddy" effect that occurs when too many layers are used in a constrained layer system. After all, if you need more than three layers, then you're probably doing something wrong in the first place.
Independent of component weight - whether it's a massive 300 pound amplifier, or a sensitive phono stage, the results are satisfying and predictable! Plus, they are tolerant to a wide range of after-market coupling devices - allowing you to "tweak" your system any way you like it.

The Frame Assembly:
Since aluminum is used for the vertical columns, we use ferrous metal for the horizontal beams. Rack frames made entirely of aluminum exhibit a phenomena we refer to as "cage effect". This is caused when vibration energy loops around the rack frame and feeds back into itself. Since this is caused by vibration along the longitudinal axis, simply applying a damping material to the surface won't eliminate the problem.
Try this simple experiment: Take an aluminum extension ladder and drop it on the ground. The loud clang sound you here is an example of this phenomena which is inherent in the sonic signature of rack frames made entirely of aluminum.
The solution is obvious. We simply use a material for the cross beams that has different properties than that of the columns. Adona rack frames are among the quietest in the industry.
The Sub-frame:
The one-piece, TIG-welded structural steel frame features column attachment rings made from 1/4 inch thick material and even the large cross beams have a wall thickness of 3/16 inch thick! In other words, this single-level stand has higher mass than many multi-shelf audio racks! Features a beautiful and durable gun-metal gray powder-coated finish.
The Footers:
The four and one-half inch in diameter base plates are machined from solid, 3/4 inch thick billet aluminum and have 1/2-13 threads. Included with the stand is your choice of heavy-duty spikes, leveling pads or casters.
