MADE IN USA





These are highly engineered
audio equipment platforms that have been specifically designed for Decware tube gear. 

These Audio Focus Platforms get their name from their ability to turn vibration into heat instead of moving it from one place to another like a solid block of wood. The result is noticeably better image focus, and bass control.

If you read about how these actually work, you're going to want one.

Options

These platforms come in different sizes to match our amplifiers. Our larger sizes may work with other brands as well.

For example, we have five sizes that cover all of our amplifiers / preamplifiers. 

Size A - 8" x 13-1/4" x 2-7/8"

Size B - 11-1/2" x 13-1/4" x 2-7/8"

Size C - 10" x 17-1/2" x 3"

Size D - 15" x 18-1/2" x 3"

Size E - 15" x 20-1/2" x 3"

Most of our amplifiers come in hardwood chassis, so we offer the same hardwoods here to match.  They are:

Maple, Walnut/Sapele, Oak, Cherry, African Paduke and custom woods.




You can get the platform by itself as shown below,
or you can get it complete with our cones and pads, pre-located for your specific Decware amplifier as shown above.

The cones are hardwood with brass tips and locate into the platform ready to spike into the bottom of your amplifier chassis at the exact correct locations. 

The pads that the platform sets on are made from 1/2 inch thick Sorbathane that has the correct stiffness and diameter to support and isolate the platform.

How it works

With these platforms it is about loading, which means having having an amplifier with some weight setting on it.

There is no "tuning" with this design because we are not trying couple mass to change the resonant frequency of the vibration, but rather using the platform to absorb the vibration and turn a substantial portion of it into heat.




(exploded view)


Unlike a solid block of wood which can only move vibration from one point to another, or lower the frequency of vibration by coupling its mass to the audio component, the Zen Audio Focus Platform absorbs vibration equally from both the amplifier that sets on it and from the audio rack that it sets on.  The vibration is greatly reduced leaving what it absorbed as heat in the composite resin core.

WHAT IS THE BIGGEST SOURCE OF VIBRATION IN A TUBE AMP?

Many people think that vibration control platforms are to prevent vibrations in the audio rack from entering the amplifier, and that is a small part of it yes, but do you realize that the 50/60 Hz vibration from the power transformer in a tube amplifier is 10 to 100 times greater than any air born or seismic vibrations that will ever collect in your audio rack?  Assuming of course that you didn't set your amplifier on top of the subwoofer!

Yes, the power transformer is your main source of vibration in a tube amplifier, and the tubes themselves are the specific thing in a tube amplifier that you want to keep from vibrating. 

So, you have to recognize the source of the your problem, the transformer, and then identify the path it takes through the amplifier chassis.  Once you have done that you can locate the perfect spot to couple the chassis of the amplifier to your platform.  

If your amplifier has a bottom plate, be it wood or steel, and you have placed your footers there, you have turned your bottom plate into a weighted spring sending as much vibration back into the denser part of the chassis as goes down through the footers or cones.

The highest mass of any chassis is the corners... the exact corners.  That means to collect that vibration you have to have a point on the top of an upside-down cone embedded into the exact corners of the amplifier chassis to couple the most vibration into the platform.

Once you have done that, you want to absorb the vibration, not move it into a solid block of wood expecting it to somehow fade away. 

Since we are an amplifier manufacture, we know exactly where the vibrations are in our amplifiers and the best way to reduce them.

Using tube dampers, to reduce vibration after it has entered the tube is not as effective as reducing the source of the vibration entering the tube in the first place.  That is what the Zen Audio Focus Platform does...

HOW IT WORKS CONTINUED:



In the diagram above you see two thick plinths.

The plinths are made from solid hardwood.  The particular wood used will typically be the same wood as the amplifier chassis is made from.  The most common being Walnut, Maple, Cherry, Oak, African Paduke, and Ash.

The top plinth is solid while the bottom plinth has a 4 inch hole through it's center.  Coupling the two plinths together is an 1/8" brass ring that creates a fulcrum so that the corners of both plinths can flex against.

The composite resin plug is made from epoxy resins, quartz, aluminum, brass, iron, and copper in a proprietary blend.  This completely fills the 4 inch hole in the bottom plinth as well as the ring with a super high mass that bonds the two plinths together so aggressively that they can not be forcefully separated under any condition even with tools.

Since the composite resin plug bonds with the wood so deeply, the lower plinth has considerably more mass than the top as the plug's mass becomes part of it.  This is what creates the co-mass-layer-damped system that keeps the corners from resonating on their own and what creates the heat.

The platform works equally well to absorb energy from the top  as it does from the bottom.  In fact it's so effective that you may get better performance from setting it directly on the audio shelf as opposed to using isolation pads under it depending on the mass of your audio shelf.
