In the same way as every musical performance needs a stage so a HiFi needs a stage to bring the music to life in your home. Combining the technology of the SVT rack and the bronze upgrade we effectively created a rack within a rack making the entire system more musical and enjoyable.
The X reference is a rack within a rack with each X shaped shelf supporting an SVT shelf with solid bronze feet. Finally small Bronze spike locators hold the SVT shelf and Bronze feet in place on the X shelf.
