The Japanese audio company Air Tight has announced a new monobloc power amplifier called ATM-2211. The new ATM-2211 is the successor of the ATM-211 that has been on the market since 2001. The heart of the new amplifier remains a single triode valve 211. The new ATM-2211 is expected to be launched in the first quarter of 2020. Eighteen years have passed since Air Tight launched the ATM-211. The valve amplifier brand later launched the ATM-3211, a push-pull triode amplifier with a capacity of 120 watts. Air Tight claims to have spent five years developing the new ATM-2211 from ATM-3211.
