Rega Elex Mk4

A full-width integrated stereo amp with MM phono and isolated optical/coaxial conversion.

Evidence checked / updated: 2026-10-11. Manufacturer claims and editorial system-fit assessment. No SoundPath Lab listening or measurement test.

Verified documentation

  • Manufacturer power: 72 W/channel into 8 ohms and 90 W into 6 ohms at rated supply; no complete rated-power frequency/THD condition is supplied on the model page.
  • Inputs and control: Four line inputs, MM phono, optical/coaxial 16–24-bit PCM to 192 kHz, record/preamp outputs and headphones.
  • Operation: 11 kg; no automatic power management according to the model page.

Best for

a vinyl/line stereo system needing a separate preamp output

Avoid if

USB DAC input, network playback, HDMI control or low standby-related running cost by default

Limits and unknowns

Leaving it on increases energy use. It is a stereo amp, not a multichannel processor; local speaker loads and ventilation still require checking.

Current verdict

Conditional shortlist for a vinyl/line stereo system needing a separate preamp output. The recommendation depends on the documented system conditions, not an independent sound-quality ranking.

Why it fits

A full-width integrated stereo amp with MM phono and isolated optical/coaxial conversion. This assessment is an editorial inference from the documented topology.

What it can replace

Can consolidate the functions stated in the profile when the source, load and control path meet the conditions below. The useful replacement is a function or connection gap, rather than an assumed improvement in sound.

What it cannot replace

USB DAC input, network playback, HDMI control or low standby-related running cost by default

What SoundPath Lab tested

SoundPath Lab checked primary-source model identity, the stated interfaces and conditions, and this decision profile. No device was listened to, measured, installed, firmware-retested or endurance-tested for this review.

What remains untested

Actual sound preference, noise with your headphones or speakers, software behavior, room results, connection stability and long-term reliability remain untested. Manufacturer measurements below are not SPL measurements.

System conditions

Match phono to an MM cartridge or use a separate suitable MC stage. Digital inputs accept PCM, not arbitrary TV surround streams. Read the load/ventilation instructions and connect headphones at low volume.

Alternatives by need

Brio Mk7 is the adjacent Rega size/power/control alternative; A-S801 changes the price/connectivity tradeoff. Watts with different test conditions do not establish listening superiority.

Keep or upgrade

Keep a working system if it already provides the connections and level you need. Consider this model only if its documented role solves the specific need described above; check the alternatives and all remaining costs before changing equipment.

When to reassess

Reassess after a material manual or firmware change, an independently reproduced issue, a hardware revision, or a documented change in service or repair availability. A routine update does not prove that an existing issue is resolved.

Ownership evidence

No six-month ownership study was performed. Battery wear, pad or stylus replacement, service dependence and local repair access should be evaluated for the actual use case. No future reliability outcome is predicted.

Firmware, manual and support

The linked official model manual was read for connection and operation conditions. Follow the manual matching your hardware and market. Current firmware, app compatibility and the long-term repair horizon remain unverified unless separately stated. Rega states a lifetime limited manufacturing-defect warranty; wear, consumables, unauthorized changes and country-specific conditions are excluded or conditional.

Launch day, globally uniform price, local authorized stock, repair turnaround and guaranteed support end date were not established in this review. Regional store offers are not global availability. No defect-free or six-month reliability claim is made.

Revision record

2026-10-11 — Promoted from L1 to L2 after full Decision Profile review. Stable product identity retained; source conflicts and untested behavior remain visible. L2 is evidence coverage, not independent test acceptance or automatic recommendation.
