Rega Elex Mk4 Integrated Amplifier Announced
Rega's Elex Mk4 integrated amplifier features an onboard MM phono stage, DAC, headphone amplifier, and more.
Rega's Elex Mk4 is the latest product from the English hi-fi brand to get a new version with the Elex Mk4 replacing 2014's Elex-R and boasting a sleeker design, improved circuitry and an integrated DAC handling up to 24/ 192 decoding.
Rega's class A/B power amplifier circuit provides 72W per channel into 8 ohms or 90W into 6 ohms, with power provided by a “quiet, multi-stage linear supply”. Additionally, the digital and analogue supply rails are “galvanically isolated” to mitigate signal interference.
You get four line-level inputs alongside “galvanically and optically isolated” optical and coaxial digital inputs utilising a “Wolfson S/PDIF receiver IC to provide exceptional detail and clarity”, a first for an Elex amp. The built-in DAC is based on Rega's own DAC-R circuit, while a Wolfson DAC and Rega-designed discrete line-driver circuit are used for output. Rega underlines that “the analogue side of the circuit is not affected in any way by the introduction of digital inputs.”
As you would expect, Rega has also included a carefully integrated MM phono stage. Here, we're informed the RIAA equalisation has been split into two stages to minimise interaction. Also, polyester capacitors have been used in the signal path, and polypropylene capacitors are used in the RIAA equalisation circuits.
There is also a headphone output on the front panel for late-night listening with a 6.3mm jack.
The Rega Elex Mk4 will be available very soon in North America, selling for $1,875 USD.

The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories.
