Power amplifiers mono — PS Audio BHK Mono 600 Power Amplifier

The BHK Mono 600 Power Amplifier is a flagship-tier monoblock from PS Audio, built with a substantial 1.6kVA power supply, smoothing capacitors totalling 336,000 microfarads, and the visual and sonic character of a tube rectifier. The BHK Mono 600 brings PS Audio's most storied American engineering to a serious, hybrid tube-and-transistor monoblock format.

Key specs that matter

Input impedance is a substantial 200,000 ohms balanced or 100,000 ohms single-ended. Gain is 30.5dBu. Frequency response spans 10Hz to 100,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is under 0.002% at 1W into 8 ohms at 100% global feedback. Maximum power consumption is a substantial 1,500W. At 436 x 286 x 357mm and 49kg, the BHK Mono 600 represents a serious commitment reflecting PS Audio's flagship-tier monoblock engineering.

Sound and use context

Expect the magical sound quality PS Audio states the BHK 600 delivers from the very first moment of playback, with the substantial 1.6kVA power supply and massive 336,000-microfarad capacitor bank combined with the tube rectifier's characteristic warmth delivering flagship-tier dynamic authority.

Pairing

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

Alternatives

PS Audio's own broader BHK series offers related, more compact alternatives within the same considered hybrid tube-and-transistor engineering philosophy.
