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 Osiris is rated at 160 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 160 watts into 8-ohms
- 250 watts into 4-ohms
How loud will 160 watts actually play in your room? →
Which speakers suit the Rega Osiris?
160 W into 8 ohms, 250 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the Rega Osiris 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 Rega Osiris Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Rega Osiris amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

How much power does the Rega Osiris have?
The Rega Osiris delivers 160 watts x 2 channels into 8 ohms and 250 watts x 2 channels into 4 ohms. It increases its output into 4 ohms, so it has some headroom for harder-to-drive speakers.
Does the Rega Osiris use vacuum tubes?
No. The Rega Osiris is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Rega Osiris?
The Rega Osiris 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 Osiris have a built-in DAC?
No. The Rega Osiris 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 Osiris?
No. The Rega Osiris 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 Osiris have Bluetooth?
No. The Rega Osiris does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Rega Osiris have a headphone output?
No. The Rega Osiris does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the Rega Osiris cost?
The Rega Osiris has a manufacturer's list price (MSRP) of $11,600.
