nuclear submarines and high-end audio equipment have in common? Both
need to operate under conditions of optimal silence. Silence is what
makes the latest SSN’s and SSBN's so effective as weapons of stealth.
They are just about undetectable – the ultimate silent-running
machines. State-of-the-art audio systems also demand silent running.
Their only job is to reproduce music. Sounds extraneous to the audio
signal are unwelcome intruders. Any vibration, whether emanating from a
speaker or a transformer, affects an audio system’s output.
the world of defense technology, silence has been a closely guarded
secret. The implementation of the latest military technology in
high-end audio products has been elusive – to say the least! SRA
crosses that line.

only the finest materials. We test every aspect of design and
construction extensively. Each SRA isoBASE is built by hand for the
audio component it serves. We use remarkably few off-the-shelf parts.
Each isoBASE consists of a low-mass, rigid housing enclosing a
center sub-assembly we call the raft. At the heart of the isoBASE a
series of modules encapsulate proprietary, lab-developed damping
materials. These customized modules are designed to control and cancel
resonance within a given frequency range. Their ability to rapidly
change cell structure in response to external factors makes the isoBASE
the world’s most effective audio isolation device.
A movement or vibration
creates friction in the module. Friction produces heat. Relative to the
component’s weight, heat modifies the compound’s darometer, i.e., its
softness or firmness when in a static state, in an anticipated manner.
As vibrations pass through the modules, their amplitude gradually
decreases until they dissipate entirely.
each platform precisely for the weight and weight distribution of the
component it supports. Further, we take figure in our calculations the
type of component the isoBASE serves – amplifier, preamplifier, tube or
solid state; analog or digital; dynamic or electrostatic speaker, etc.
And we also take into account the materials used in the component’s
construction. Further, we ascertain the type of environment in which
the isoBASE will operate. This too can make a difference (1see
footnote). A great deal of calculation and forethought go into each
SILENT RUNNING AUDIO isoBASE. And that’s why we call it Component
advertising claims seem over the top because they are. From hi-fi’s
inception, audio designers have been rewriting the laws of the physical
universe. But consider: if your system is on a cement floor, in a
basement listening room, say, it will react differently to vibration
than if it’s arrayed on a suspended floor, e.g., in a living room, as
it will on rack shelves. At the customer’s request, an Ohio Class XL
plus platform is tweaked to accommodate these nuances. That’s why we
ask where the sound system operates. Materials make a difference too.
An equipment enclosure constructed from 1/8” inch-thick aluminum will
have a different resonance frequency potential than the same enclosure
constructed from 1/4” aluminum, or wood, or steel. To repeat: Component
