Rega Elex Mk4 integrated amplifier

Rega Elex-R stereo integrated amplifier.

What we Say:

The Rega Elex Mk4 is latest generation Elex from Rega. It now sports a high performance DAC, moving magnet (MM) phono stage and a headphone amplifier. The Rega Elex Mk4 is the next model up from the Brio.  The Elex Mk4 takes full advantage of the larger case size and the benefits that it brings to offer increased performance.

The Elex-R amplifier is able to deliver 72W per channel into 8 Ohms and 90W into 6 Ohms.  The extra case size means that it is much more thermally efficient and also features a larger transformer in the power supply.

The extra space means that circuit layout can be further optimised and this results in a big jump in performance and power output. It uses a combination of both leaded and surface mount components as both types of components have their advantages in different parts of the circuitry. This is a lot of amplifier for the money and thanks to its clever design also sounds great.

The Rega Elex-R is a multi award-winning amp that deserves its place in your home.

What they say:


The Elex MK4 is a high performance stereo integrated amplifier designed to deliver the purest musical performance. Housed in a brand new case to match the rest of the Rega range, the MK4 builds on previous Rega designs using our multi-award winning class A/B power amplifier circuit which delivers an impressive 72W per channel into 8Ω loads (90W into 6Ω). New rear connectivity options are available with the Elex MK4 now including a Rega DAC circuit with two digital inputs and a high quality headphone output conveniently located on the front panel.


Bringing your music to life

The Elex MK4 is capable of driving difficult loudspeakers with ease and will integrate perfectly into any audio system by offering a wider range of connectivity options. In addition to the line level, digital inputs and a high quality moving magnet phono stage,  you will also find Pre-out and Record Out functionality alongside a headphone output. Special attention has been paid to the selection of key audio components. Discrete circuitry, high quality relays, polypropylene capacitors and Sanken output transistors are used throughout the design.
