Rega Integrated 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 Rega Aethos is rated at 125 watts RMS into 8-ohms. Rega provides this wattage at a THD (Total Harmonic Distortion) of 0.007% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 125 watts into 8-ohms (10 Hz-30 kHz) at 0.007%
- 156 watts into 6-ohms

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Rega Aethos is rated at 125 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Rega Aethos 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.
Inputs and Outputs
Besides the performance specs of the Rega Aethos, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
Rega Aethos 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 Rega Aethos. 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
Rega Aethos doesn't have a phono input so in order to play your vinyl albums, Rega Aethos has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Rega Aethos Pros and Cons

How much power does the Rega Aethos have?
The Rega Aethos delivers 125 watts x 2 channels into 8 ohms and 156 watts x 2 channels into 6 ohms.
Does the Rega Aethos use vacuum tubes?
No. The Rega Aethos is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Rega Aethos?
The Rega Aethos 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 Rega Aethos have a built-in DAC?
No. The Rega Aethos 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 Rega Aethos?
No. The Rega Aethos 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 Rega Aethos have Bluetooth?
No. The Rega Aethos does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
How much does the Rega Aethos cost?
