There are 10 PS Audio amplifiers in our database. Below you can see the main specs of these amps.
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 Stellar M700 is rated at 350 watts RMS into 8-ohms. PS Audio provides this wattage at a THD (Total Harmonic Distortion) of under 0.02% at 1kHz, 1W into 4 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:
- 350 watts into 8-ohms at under 0.02% at 1kHz, 1W into 4 ohms
- 700 watts into 4-ohms
- 105dB Signal to Noise Ratio

Which speakers suit the PS Audio Stellar M700?
350 W into 8 ohms, 700 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
PS Audio Stellar M700 is rated at 350 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 Stellar M700 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 Stellar M700 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the PS Audio Stellar M700 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Are you nuts? |
| Small Room | Bad |
| Mid-size Room | Poor |
| Large Room | Good |
| Very Large Room | Good |
Inputs and Outputs
Besides the performance specs of the PS Audio Stellar M700, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
PS Audio Stellar M700 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 Stellar M700. 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 5 amps that have Bluetooth Connectivity:
Phono Input
PS Audio Stellar M700 doesn't have a phono input so in order to play your vinyl albums, PS Audio Stellar M700 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 Stellar M700 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 Stellar M700 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 350 watts into 8 ohms rising to 700 into 4, which points to a power supply with real current in reserve.
- ✓350 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Class D output stage, so it runs cool and wastes little power as heat - which is how it fits in a small case.
- ✓Signal-to-noise ratio of 105dB, so the amplifier itself should be inaudible between tracks.
- ✓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.
