Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements.The PS Audio BHK Mono 300 is rated at 300 watts RMS into 8-ohms. PS Audio provides this wattage at a THD (Total Harmonic Distortion) of under 0.01% at 1kHz, 1W into 8 ohms which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 300 watts into 8-ohms at under 0.01% at 1kHz, 1W into 8 ohms
- 600 watts into 4-ohms
- 85dB Signal to Noise Ratio

Which speakers suit the PS Audio BHK Mono 300?
300 W into 8 ohms, 600 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the PS Audio BHK Mono 300 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.

How much power does the PS Audio BHK Mono 300 have?
The PS Audio BHK Mono 300 delivers 1000W into 2 ohms. Discontinued from new production in 2025. Sold as a pair, $16,998 the pair.. Its output almost doubles into 4 ohms, which points to a strong power supply that can hold its composure with demanding, low-impedance speakers.
Does the PS Audio BHK Mono 300 use vacuum tubes?
Partly. The PS Audio BHK Mono 300 is a hybrid - vacuum tubes in the input and driver stages feed a solid-state output stage, so it takes some of the character of a valve amplifier with the power and the load tolerance of a transistor one.
How long do the tubes in the PS Audio BHK Mono 300 last?
Output valves are a consumable. In normal domestic use a set lasts somewhere between about 2,000 and 5,000 hours - a few years for most people - and they degrade gradually rather than failing outright. Input and driver valves last far longer, often the life of the amplifier. Check the warranty card before you buy: valves are almost never covered by the amplifier's own parts warranty, and are usually warranted separately for 90 days to a year.
What amplifier class is the PS Audio BHK Mono 300?
The PS Audio BHK Mono 300 uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the PS Audio BHK Mono 300 have a built-in DAC?
No. The PS Audio BHK Mono 300 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the PS Audio BHK Mono 300?
No. The PS Audio BHK Mono 300 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the PS Audio BHK Mono 300 have Bluetooth?
No. The PS Audio BHK Mono 300 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the PS Audio BHK Mono 300 have a headphone output?
No. The PS Audio BHK Mono 300 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the PS Audio BHK Mono 300 cost?
The PS Audio BHK Mono 300 has a manufacturer's list price (MSRP) of $8,499.
