Critical Mass Systems is well known for making some of the finest (and largest) high-end audio equipment support systems money can buy. So, it might come as something of a shock to discover that CMS maven Joe Lavrencik’s best-ever product might just be an inconspicuous vibration-control foot called the Center Stage2

Joe is being perhaps understandably reticent about discussing the inner workings of the Center Stage2. According to the company’s white paper, Center Stage2is made by “choosing and sequencing materials that possess the perfect combination of damping, elastic modulus, and thin rod speed to lock in the desired effect.” That effect is, “a catalyst in a complex energy reaction that occurs between your equipment and its environment.” The idea is that kinetic and vibrational energy act in an unregulated and undamped manner inside a product and Center Stage2can “change the prevailing state of equilibrium in that energy reaction and to permanently hold it in a reduced or damped state.”  

According to Lavrencik, “Center Stage2was designed to exacting specifications using material science and First Law of Thermodynamics principles.  It also relies heavily on the Second Law of Thermodynamics to meet its performance objectives. There is no new physics in Center Stage2, we’re simply applying physics in new ways to an audio foot.” Lavrencik focused on three aspects: impedance mismatching to greatly reduce vibration moving upward from the floor, the reduction of the noise inherent to the materials used to fabricate the foot, and a means to transfer entropy out of the component.

What this means in real terms is a black anodised aluminium foot with an almost free-spinning aluminium foot pad on the base, and the top is covered with stiff, black paper-like material. You have three sizes of the foot, dependent on the mass of the device and the size of its own foot. You need four feet per device. They are placed on the underside of the device, not on a screw-head or as a footer under the component’s own feet. It works on practically everything except turntables and loudspeakers (but including turntable power supplies).

Here’s where it gets weird: you stick a quartet of Center Stage2under your source component and… it sounds terrible! Add a set to your preamp, power amp, or integrated amplifier and the sound gets even worse. Your hitherto full, detailed, and dynamic sound is transformed into something thin, muddy, and flat. Next day, it gets a little better, then it gets worse, then better still, then worse again, and so on. Generally, it fills itself in from the bass upwards, with the bottom end being the first to return to prior levels. You’ll get about a week and a bit’s worth of audio mood swings. And it’s at that point the transformation happens and the system blossoms. 

You notice this change by a shift in your internal dialogue. “I’d forgotten just how good that really is!” (referring to both record and equipment) seems to be the first sign. About an hour later, you find yourself composing a thank-you email to the designers of the components in your system. Although it’s the bass that first comes back, it’s the midrange that seals the deal; the enhanced clarity, the walk-in detail to the soundstage, which seems to not change a thing, all the while being far more enveloping than before. This is no small change, and as the listening progresses, you begin to find this feeling of being immersed in the music, which truly transforms your listening sessions, and it becomes uppermost in your requirements for a good system. Everything just seems more natural, more real, and more like the recording engineers and the equipment designers had in mind when they got creative. And the Center Stage2is also one for the Pace, Rhythm, and Timing (PRaT) obsessives, in that a device resting on a set of four Center Stage2seems to keep time better than ever. But it’s that envelopment that really captivates you and takes your attention. If you were a PRaT obsessive before you put a set of Center Stage2in situ, you become a sonic envelopment obsessive who likes a bit of rhythm afterwards.

I’ve used all kinds of feet and pods and the like before. The best of them seem to align one product to another harmoniously. Center Stage2is not like that; instead, it erases many of the impediments that hold back a device. In the process, it gives the device resting upon these devices a promotion. Even the best audio devices have hidden strengths the Center Stage2can unveil.
