The Model A v.2 isolation platform is a two-piece system, which employs resonance damping within its fine hardwood exterior. The newly designed insert/inlay is constructed from solid hardwood with chambers within the inserts inner core. Unlike the sealed design of the original version 1, the version 2's open chambers that are uniquely designed to allow users to fill with materials of their choice. This design captures and mitigates resonance over a large range of frequencies without compromising the beauty of fine furniture.
At Core Audio Designs, we recommend the use of multiple materials to increase the damping effect. The insert/inlay arrive preloaded with 45 parts lead shot and 55 parts clay and sand. The mixture of lead, clay, and sand, was selected for their mass loading and low resonant properties. The Model A v.2 isolation platforms have been engineered to meet the needs of discerning audiophiles. Our customers know the value and quality of high-end components, and they deserve racks and accessories that not only match the aesthetics of their listening space, but also serve to dial in the whole experience. The components of our Model A v.2 let the active components perform at their very best, creating a more ideal platform for performance than would otherwise be achievable.

The goal of our design for the Model A v.2 isolation platform was to build a cost effective, high mass, resonance free structure that performs like a mechanical diode draining unwanted resonance from transformers, motors, and other interferences. At Core Audio Designs, we have proudly attained that goal.

CORE Designs travels the road less taken, opting for tonality. Black walnut is their wood of choice. It has the definition and smooth frequency response of maple, but none of its demure refinement. It differs in that it augments the lower-midrange and actually adds flesh. You can expect darker and more saturated tone, along with big, full-bodied, solid images.
The CLD replaced the Harmonix TU-888 "System Tuning Board" (MSRP $2400/each), an item I considered mandatory after the briefest audition. I didn't have to make a huge mental adjustment. Tonality is right there alongside the Harmonix TU-888, flesh is even more abundant, and it's certainly more neutral-there is clearly none of the signature Harmonix space and soul, resonance and bloom. You know what? I'm not missing them that much. Amazing-at 1/7 the cost!"

"Then I found perhaps the best support: a solid walnut soundboard from CORE Designs. These come with their CLD amp stands. It happens to be a perfect size and I had an extra available. I placed some cork contact paper strips on it and laid it on top of the TAOC shelf. Wow, what mass and solidity!"
