The Ultimate Enhancement

There were several objectives behind the development of Center Stage2M. Firstly, we wanted to build upon the proven approach developed for the LS (loudspeaker) series of Center Stage products.

Secondly, and most important, we wanted the performance improvement of each new Center Stage2M product to be so great, it leapfrogged its bigger brother in the CS2 line up. In better words, the Center Stage2M 0.8 had to be better than the CS2 1.0. The Center Stage2M 1.0 had to be better than the CS2 1.5 and the Center Stage2M 1.5 had to set a new standard for audio footer performance in the industry.


  • Various frame dimension choices: flexible
  • Load limit: approximately 200 lbs (91 kilos) per component (higher limits are an option)
  • Shipping weight: approximately 55 lbs (25 kilos) for standard size

Center Stage2M accomplishes every objective we set by a wide margin. We are thrilled with Center Stage2M and we hope you will give them a try throughout your system. The “M” stands for “MAXX”.

Center Stage2M is direct trickle-down technology garnered from advancements made in the development of the Center Stage LS series of loudspeaker feet. The LS series of Center Stage products reduce stored loudspeaker cabinet resonances and entropy to a vanishing level resulting in enhanced clarity and musicality across the audible spectrum.

Rather than approaching the problem of reducing vibration using new untested methodologies, we decided to “use the advancements we knew worked well with loudspeakers”. We used tested design fundamentals resting within the discipline of material science to determine the correct sequencing of the Center Stage2M materials. We established the proper proportions of the materials. And, we added damping in the very last stage in an amount that would eliminate the internal noise of the product and the component without rolling off the top end of the acoustic envelope.

What to expect during settle in

The settling in period is generally 7 to 10 days, but it can be longer. Because Center Stage Ultra will dramatically change the current electromechanical equilibrium of your components, you should expect your system to temporarily degrade at the outset. This is perfectly normal. Your soundstage will then begin to reconstruct itself as it establishes a new and better equilibrium point.

In the end stage, the settling changes will become ultrafine and be largely experienced in the high frequencies. They will be barely perceptible unless you really focus and then variances will disappear altogether. It is extremely important to let the system play for at least 14 days before assuming it has reached equilibrium. Playing a system 24/7 is not necessary, but the more playing time the better. Think of it like breaking in a brand-new component where break-in time is normal.

Your end of the Bargain, or Making the Experience Better

Center Stage Ultra is good for beginners and advanced listeners, so long as you exercise extreme patience during the settling period. Sonic fluctuations you may experience during the settling period will subside as time passes. Here’s what you need:

  • Components crafted by a known and reliable manufacturer. Your components do not need to be among the “most expensive” or the purported “best” in the world. You will experience excellent results with low cost components. A host of components were used to design Center Stage Ultra, some of them very low cost. This was done to assure consistency of performance. It is certainly true, however, that the better your components, the better your results.
  • Neutral wiring crafted by a known and reliable manufacturer. Some wiring is a “tone control”. Tone control wiring is not necessary. The more invisible your wire, the less it makes its presence known in your system, the better your results.
  • A Clean Circuit. It is critically important to make sure that “cheap” power supplies from computers, screens, servers and most turntables etc. are plugged into a circuit separate from the circuit servicing your main components. The dirt from these low-end plug-ins will contaminate your signal. You may not have heard it before, but you will certainly hear it with Center Stage Ultra.
  • Stable rack(s) and/or stand(s). Home furnishings are fine. Center Stage Ultra was vetted on various flat wooden surfaces with Janka ratings of 1200 and higher equating to an elastic modulus of 4 GPa or greater. This means that virtually any flat surface will net tremendous results. Having said this, the better the surface with respect to its associated and/or inherent technological properties, the better the results. The results on CMS racks is superlative.
  • Proper loudspeaker set up. This is essential. Center Stage Ultra was designed to be most effective in 2-channel stereo system listening rooms with conventional loudspeakers of appropriate size and design for the room, and with seating positions reasonable and appropriate for the loudspeaker and room dimensions.
  • When you put Center Stage Ultra in, pull every tweak out. Center Stage Ultra will take about 7 to 10 days to settle. Be slow, careful and cautious about adding any other device(s) back into your system. Adding Center Stage Ultra under more of your components is the only means to realizing the full “Total Immersion Effect” so highly valued in high end audio.
