PS Audio Power Amplifier Series
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 600 is rated at 600 watts RMS into 8-ohms. PS Audio provides this wattage at a THD (Total Harmonic Distortion) of under 0.002% 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:
- 600 watts into 8-ohms at under 0.002% at 1kHz, 1W into 8 ohms
- 100dB Signal to Noise Ratio

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
PS Audio BHK Mono 600 is rated at 600 watts into 8 ohms, which puts it in our Over 180 watts band. That is the top band we cover, so there is no step up from here - if it is not enough, the answer is more sensitive speakers or a smaller room, not more watts.
When pairing the PS Audio BHK Mono 600 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.
What size of room is the PS Audio BHK Mono 600 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the PS Audio BHK Mono 600 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |

Bluetooth Connectivity
PS Audio BHK Mono 600 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your PS Audio BHK Mono 600. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 2 amps that have Bluetooth Connectivity:
Phono Input
PS Audio BHK Mono 600 doesn't have a phono input so in order to play your vinyl albums, PS Audio BHK Mono 600 has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Balanced connections
PS Audio BHK Mono 600 has a balanced XLR input. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.
PS Audio BHK Mono 600 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓600 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Hybrid design, with a valve stage ahead of a solid-state output section.
- ✓Signal-to-noise ratio of 100dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.002%, an order of magnitude below what is generally held to be audible.
- ✓A monoblock - one per speaker, so the two channels share no power supply and no chassis.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Detachable mains lead (IEC).
- ✗Being a monoblock, you need two of them for stereo.
- ✗A power amplifier has no volume control and no input selection - it needs a preamplifier, or a source with a variable output, in front of it.
- ✗It weighs 49kg - check the shelf, and plan on a second pair of hands.

How much power does the PS Audio BHK Mono 600 have?
The PS Audio BHK Mono 600 delivers Gain switchable 26.0dB or 30.5dB. PS Audio publish no 4 ohm figure. Sold as a pair, $29,999 the pair..
Does the PS Audio BHK Mono 600 use vacuum tubes?
Partly. The PS Audio BHK Mono 600 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 600 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 600?
The PS Audio BHK Mono 600 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 600 have a built-in DAC?
No. The PS Audio BHK Mono 600 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 600?
No. The PS Audio BHK Mono 600 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 600 have Bluetooth?
No. The PS Audio BHK Mono 600 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 600 have a headphone output?
No. The PS Audio BHK Mono 600 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the PS Audio BHK Mono 600 cost?
The PS Audio BHK Mono 600 has a manufacturer's list price (MSRP) of $14,999.
