The Elex Mk4 is an integrated amplifier with built-in DAC by Rega that delivers 72 watts x 2 channels into 8 ohms and 90 watts x 2 channels into 6 ohms. It was released in 2025. It is a 2-channel design using a Class A/B output stage. Speakers connect via binding posts. It has a built-in DAC (Rega DAC circuit, one optical and one coaxial input), so you can play digital sources directly with no separate DAC unit needed. It also has a phono input, so a turntable can connect straight to it. The Rega Elex Mk4 has an MSRP of $1,895.
Rega replaced the older Rega Elex-R with this model. Follow the link to read our detailed comparison of these models:

There are 8 Rega amplifiers in our database. Below you can see the main specs of these amps.
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 Elex Mk4 is rated at 72 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:
- 72 watts into 8-ohms
- 90 watts into 6-ohms
How loud will 72 watts actually play in your room? →
Which speakers suit the Rega Elex Mk4?
72 W into 8 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Rega Elex Mk4 is rated at 72 watts into 8 ohms, which puts it in our 61 to 90 watts band. The next band up is 91 to 120 watts, which is worth about 1.5dB 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 Up to 60 watts band and better speakers.
When pairing the Rega Elex Mk4 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 Elex Mk4 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Rega Elex Mk4 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Poor |
| Small Room | Average |
| Mid-size Room | Good |
| Large Room | Average |
| Very Large Room | Poor |

Bluetooth Connectivity
Rega Elex Mk4 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 Elex Mk4. 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 Elex Mk4 features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
DAC and Digital Music
The Rega Elex Mk4's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC. The DAC chip that is used in the Elex Mk4 is the
Rega DAC circuit, one optical and one coaxial input, and supports resolutions up to
24-bit, 192KHZ.
Rega Elex Mk4 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓72 watts per channel into 8 ohms.
- ✓5 analogue inputs, enough for a full rack of sources.
- ✓Built-in DAC handling 24-bit / 192, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Phono stage built in (MM), so a turntable needs no separate preamplifier.
- ✓Pre-outs (Pre out and record out) leave room to add a power amplifier or an active subwoofer later.
- ✓Headphone output.
- ✗The phono stage is moving-magnet only; a moving-coil cartridge would need a step-up or an external stage.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
