To be fair, I just heard of Box Furniture so I can’t make a direct comparison. But common sense should tell you that a piece of wood furniture marketed as an audiophile rack can’t begin to compete with a Sistrum rack or platform that’s scientifically designed to optimize the performance of components.
My Cary 303/300 CD player and Cary 300 SEI integrated amplifier (modified by Stuart Jones - Chapman Audio Systems) are on two special edition Sistrum platforms filled with Micro-Bearings. The platforms rest on APCD-5 Coupling Discs which are on a wood floor. Robert told me the APCD-5 actually absorbs more energy than the wood floor itself! I’m currently using the amp for headphones only so there’s no floor vibration. And I can tell you the difference between listening with the CDP on the floor compared to listening with it on the Sistrum is NIGHT AND DAY — much greater musicality, nuance, detail, dimensionality, dynamics, and emotional engagement with the music!
