Power amplifiers mono — Boulder 3050

The 3050 is Boulder's flagship-tier monoblock power amplifier, sitting above the 2150 with even more staggering output power and mass. The 3050 represents Boulder's most ambitious current statement in monoblock power amplifier engineering.

Key specs that matter

Input impedance is 200,000 ohms balanced or 100,000 ohms single-ended, matching the 2150. Output power is a staggering 2,100W into 8 ohms, rising to an extraordinary 3,000W into 4 ohms - considerably more than the 2150. Gain is 26dBu, matching. Total harmonic distortion plus noise is 0.0005% from 20Hz-2kHz or 0.0035% at 20kHz into 8 ohms. At 226.9 x 161.1 x 346.5mm and a staggering 161kg, the 3050 represents Boulder's absolute current flagship monoblock engineering ambition.

Sound and use context

Expect extraordinary dynamic authority reflecting the extraordinary 3,000W-into-4-ohms output combined with the near-immeasurable distortion figures, representing Boulder's absolute current flagship monoblock engineering.

Pairing

As a monoblock, two units are needed for a stereo pair, and Boulder's own preamplifier catalogue offers natural, brand-coherent pairings.

Alternatives

Boulder's own 2150 offers a somewhat more accessible flagship-tier alternative within the same broader monoblock catalogue.
