The Brinkmann Calvin is a high-performance transistor preamplifier designed for audiophiles who seek exceptional sound quality. With its meticulously handcrafted construction and thorough testing process overseen by Helmut Brinkmann himself, the Calvin delivers outstanding audio reproduction. This model features four line-level inputs along with a dedicated MM/MC phono input, making it a versatile choice for various audio setups. The preamplifier is known for its intricate design where every component is purposefully selected to achieve the desired sonic result. Specifications include a total harmonic distortion (THD) of 0.01% and an intermodulation distortion (IM) of 0.05%, ensuring clean sound. Its signal-to-noise ratio is rated at 92 dBA for line input, while for MM/MC it is 80 dBA and 78 dBA respectively. The frequency response ranges from DC to 250 kHz for line input and from 20 Hz to 50 kHz for phono input. Output voltage can reach a maximum of 12 V with an output impedance of less than 1 kOhm. The input resistance for line is 20 kOhm, while it is set at 600 Ohm for MC and 50 pF for MM with a weight of 27 kg, including both the preamplifier and power supply. It measures 300 x 95 x 310 mm including a granite base and features a complete accessory package which includes the preamplifier, power supply, remote control, granite base, and original packaging. The Calvin has an estimated price reduction compared to its original €7,500 price tag, with second-hand listings currently at approximately €2,900.
