About the Aikido Phono 1+
The Glassware Audio Aikido Phono 1+ is a well-engineered, handmade phono preamplifier designed for moving magnet (MM) cartridges. It features a discrete circuit design with six JFET transistors per channel, housed in a rugged metal enclosure. The preamp offers selectable input impedance and capacitance to match various cartridges, a gain factor of 40 dB, and a frequency response from 20 Hz to 25 kHz. It achieves a signal-to-noise ratio greater than 88 dB and distortion below 0.1%, with RIAA equalization deviation within ±0.15 dB. The device is powered by a 48 V DC supply and consumes 1.4 W. Its output impedance is relatively high at 216 ohms, so it is recommended to use a load impedance of at least 10 kOhm for optimal performance. The Aikido Phono 1+ is noted for its low noise, reliable build quality, and excellent channel separation.
