About this gear

The SR1a is a radical open-baffle headphone using ultra-thin conductive ribbon drivers instead of conventional dynamic or planar diaphragms, delivering extremely fast transient response and a sense of speed closer to a ribbon tweeter than a typical headphone. Because of its very low impedance, it requires a dedicated amplifier or a step-up transformer box rather than a standard headphone output, making it a system-level commitment rather than a plug-and-play purchase. It's aimed at experienced listeners chasing an open, speaker-like soundstage and texture that few traditional headphones can match.
