Manufacturer's Description from Blue

The Cactus delivers a commanding, intimate presence with larger-than-life detail that is reminiscent of the world’s finest and most well respected vintage designs. At a distance, the Cactus’ B7 capsule delivers every nuance in the room, with finely focused resolution and clear, musical frequency response to the extremes of the audible spectrum. Up close, with its detailed highs and smooth midrange, the nine-pattern Cactus excels at delivering a vocal or solo track right to the front of the mix. The amplifier is a transformer-balanced single vacuum tube subminiature pentode in a triode mode, along with the highest quality hand-selected electronic components to ensure absolute minimum noise and distortion.
