Ultra moves the length-calibrated network into a machined and polished acrylic module, damped with epoxy resin and set on isolation feet. The module is non-magnetic, so the field around the network is not constrained by its housing. Gold-plated connectors and heavy precision-wound OFHC stranding carry over from Super. Standard or biwire, handcrafted in the USA, upgradeable to Reference or above.
