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

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:

  • Cambridge Audio Edge A - MSRP 6499$ - Compare w/ Aethos

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.
