Rega Aura MC Phono Preamplifier

Rega's Reference Moving Coil Phono Stage

The Rega Aura MC is a dedicated moving coil phono preamplifier, and Rega's flagship reference design. It's built exclusively for moving coil cartridges, with no moving magnet mode to compromise the circuit.

Rega's more affordable AOS MC borrows heavily from the Aura's circuit approach. The Aura remains the larger, full-width original. It ships in a substantial 350 by 435 by 88mm chassis. At 13kg, its weight reflects an outboard-grade power supply inside.

Rega describes its design philosophy as maximum minimalism. That means stripping out extra functions and tunable filters that could hurt signal purity. A three-stage, all-symmetrical circuit handles amplification. Its input stage uses parallel Linear Systems ultra-low noise FET transistors. That approach eliminates coupling components between the cartridge and the first gain stage.

Relay-Switched Precision for Reference Cartridges

Gain switches between two relay-controlled settings: 69.5dB and 63.5dB. Resistive loading offers five values: 50, 100, 150, 300, and 400 ohms.

Capacitive loading adds five more options, from 1,000 to 5,700pF. Rega switches all of these settings through relays rather than mechanical contacts. That choice is aimed at a cleaner, more repeatable signal path over years of use.

RIAA accuracy is rated within ±0.2dB from 100Hz to 50kHz. Frequency response spans 13.5Hz to 100kHz. Total harmonic distortion stays at just 0.03%.

A symmetrical, discrete tracking power supply runs at 60% higher voltage than typical designs. Each internal stage gets its own localized, LED-referenced power as a result. Relay-controlled mute and mono switching round out the front panel.

What Reviewers Are Saying

Ed Selley reviewed the Aura alongside Rega's Naia turntable for AVForums in December 2023. He described its noise floor as being "in a different class." Music, he found, was "delivered from a backdrop of absolute silence and the result is startlingly vivid."

He wrote that "the Aura shines with the Naia and it shines brighter than even I suspected it could." That's a strong statement, given the price and pedigree of the turntable it was paired with.

Jason Kennedy reviewed it for Tracking Angle in November 2024. He called it "a warmer and more inviting partner" for Rega's own turntable and cartridge. He also praised its timing. He described "a total absence of blurring when it comes to leading and trailing edges."

Kennedy summed it up simply. "This phono preamp is a musical conduit," he wrote, "that gets out of the way and lets the recording speak for itself."

Who Is This Preamp Best For?

• Owners of reference-grade moving coil cartridges. Its three-stage symmetrical circuit and relay-switched settings target the lowest possible noise floor.
• Listeners building a genuine flagship system. The Aura is Rega's reference phono stage, sitting above the more affordable AOS MC.
• Owners of hard-to-match moving coil cartridges. Five resistive and five capacitive loading values allow a genuinely fine match.
• Listeners who want proven, independently reviewed performance. Two named reviewers at established publications praised its silence and timing.
• Not the right fit for anyone using a moving magnet cartridge. This model has no MM input or gain setting at all.

How Does It Connect to Your System?

Run your turntable's phono cable into the Aura's input, matched to a moving coil cartridge. Connect its balanced output to your amplifier or preamp.

Set the gain, resistive loading, and capacitive loading to match your cartridge's specifications. Do this before you start listening. Correct loading affects both tonal balance and stability.

Use the mute switch when handling cables or swapping cartridges. Use the mono switch when playing mono pressings, for a cleaner, more focused center image.

Pairs Well With

Building your system? Here are some great companions for the Rega Aura MC:

• Turntables without a built-in phono stage
• Reference moving coil cartridges matched to its extensive loading options
• Interconnect cables to connect its output to your amp

Frequently Asked Questions

Does this work with a moving magnet cartridge?

No. The Aura is a dedicated moving coil design with no moving magnet input or gain setting.

How is this different from the Rega AOS MC?

The AOS MC borrows its core design approach from the Aura. It comes in a smaller half-width case at a lower price. The Aura is the original, full-width reference design, with a larger power supply and more loading choices.

How do I set the gain and loading?

Front-panel controls switch relay-controlled gain, resistive loading, and capacitive loading. Check your cartridge's specifications before setting them.

What's the warranty?

Rega covers the Aura with a lifetime limited warranty against manufacturing defects.
