The Boulder 2060 is a stereo power amplifier produced from 1997 until 2014, known for its exceptional build quality and sonic performance. It delivers 600 watts per channel into 8 ohms, with peak outputs of 1200W into 4 ohms and 2400W into 2 ohms. The amplifier features a fully balanced design with 40 bipolar output transistors per channel and uses load-sensing Class A biasing to maintain ultra-low distortion at all listening levels. Its power supply includes two 2500VA toroidal transformers encased in stainless steel. The chassis is machined from solid aluminum using CNC machines, with damped panels and feet to reduce resonance. It offers only balanced inputs and outputs, with a signal-to-noise ratio of 133dB and total harmonic distortion as low as 0.0005% (20Hz to 2kHz). The 2060 weighs 240 pounds and measures 18 x 10.75 x 26.75 inches. It is highly regarded for its dynamic range, tonal neutrality, and silence when idle, making it a reference amplifier for discerning listeners. The amplifier requires a robust power supply, typically a 30A 220V circuit, due to its high power consumption and Class A operation.
