45W SET Monos

About the 45W SET Monos

The Audio Mirror 45w SET monos are single-ended triode (SET) monoblock amplifiers delivering 45 watts per channel into 8 ohms, utilizing Russian 6C33C power tubes in parallel for powerful, dynamic sound with very low distortion. The design features DC coupling between input and driver stages, unique proprietary biasing, and silver wiring for signal paths. They offer a frequency response from 25 Hz to 58-65 kHz, a signal-to-noise ratio above 90 dB, and total harmonic distortion around 0.8% at full power. The amps include built-in protection circuits monitoring for tube over-biasing, arcing, and overdriving, automatically shutting down high voltage and indicating the faulty tube. The chassis is stainless steel, weighing about 42 lbs each, with dimensions approximately 9 x 9 x 18 inches. They support both single-ended RCA and optional balanced XLR inputs. These amps are highly regarded for their warm, open, and musical sound, suitable for speakers with sensitivity of 88 dB and above. The The amps are autobiased, point-to-point wired, and use custom output transformers with high-quality components throughout. They require a burn-in period for the tubes and have a delay on turn-on for protection. Overall, they are considered a remarkable value in high-end tube amplification, combining power, finesse, and tonal accuracy.
