TONEARM RESONANCE CONTROL KIT
In our listening tests, the Resonance Control Kit improves the $5000 Schroeder tonearm just as much as it upgrades the $325 Rega: you'll hear a lovely new airiness in the highs and firmer, deeper, more tuneful bass with newfound articulation. The physics are simple: bonding our 28g brass "mini Heavyhat" to the top of the headshell kills the resonances in the cartridge/headshell structure-leading to enhanced clarity in the treble and the midrange. The bottom octaves improve so much because our 28g headshell weight and 100g add-on for the arm's counterweight more than quadruple the inertia of typical tonearms. That makes a much stabler platform to resist the large stylus/cantilever excursions caused by strong bass passages.
Included are a brass headshell weight and counterweight add-on, both with machined-in triplepoints-and the CA adhesive needed for bonding them to the tonearm.
