Know before you buy
Ultra-linear mode provides the full 180 watts of power with a punchy, dynamic sound, while triode mode offers a more intimate, refined presentation with a slightly warmer harmonic character. You can easily switch between these modes to match your specific speakers or personal listening preference.
Not at all. The M-180 features a user-friendly, built-in bias meter that makes the process straightforward and safe. It allows you to monitor and adjust your tubes regularly to ensure optimal performance without needing external testing equipment.
The M-180s are equipped with dedicated 4 and 8-ohm output taps, making them compatible with a wide range of speaker impedances. With 180 watts of power, they have enough headroom to drive even demanding, low-sensitivity speakers with ease.
The slow-start circuit prevents a massive inrush of current when you first power on the amplifier. By gradually bringing the tubes up to operating temperature, it significantly reduces thermal stress and extends the overall lifespan of your vacuum tubes.
Yes, the M-180s are designed with both balanced (XLR) and single-ended (RCA) inputs. This flexibility allows you to integrate them into virtually any high-end audio system, regardless of your preamplifier's output configuration.
Each monoblock measures 14.5 inches wide, 7 inches high, and 19 inches deep. Because they weigh 55 pounds each and utilize vacuum tubes, ensure you place them on a sturdy, well-ventilated surface to accommodate their size and heat dissipation.
