Harmonic Resolution Systems SXR equipment racks have an add-on option which are called solid brace inserts. [A geeky post. I know. But it sometimes takes geeky to get the best sound… so there!]

They are often added to the top of the rack to allow support for those heavier turntables that need perhaps a 6-foot HRS isolation platform instead of the usual four-footer. In that sense I think of them often as turntable support or turntable braces.

If you get the solid brace inserts for every shelf of your SXR rack then you have an SXR Signature equipment rack.

The SXR Solid Brace Inserts triples the number of cross braces, pretensions the frame, and adds 4 friction dampers and 2 compression dampers at each component location (Isolation Base location). The added mass, stiffness, control and energy absorption capability provided by the addition of the SXR Solid Brace Inserts pushes the performance of the SXR frame towards that of the very ambitious reference level HRS Audio Stands

These heavy, indestructible pieces of metal come in the most well-packed crate ever 🙂
