1. Arcam A15 – Best Overall Stereo Amplifier

The What Hi-Fi? Award winner for best sound in its popular price class.

Pros:

• Impressive clarity and power
• Expressive dynamics and flexibility
• Multiple analog and digital connections

Cons:

• Display could be sharper
• No USB input

Arcam’s new Radia series sports an elegant all-black finish with fine yellow accents. But it’s the sound that truly shines. This mid-tier A15 delivers powerful, precise, and balanced performance no matter the input. “Arcam was a pioneer in external DACs back in the ’80s, and that expertise shows in the A15’s digital section—clear, insightful, and gripping,” our reviewers noted.

The stereo soundstage is wide, stable, and well-layered. It handles sudden dynamic shifts effortlessly, offering both muscle and finesse, delicately tracking multiple instruments with skill.

We were initially concerned the A15 might not outdo the excellent but smaller A5, yet it clearly surpasses it in purity, scale, and accuracy—justifying its higher price (starting around $1,100).

Bonus points for a built-in MM phono stage—absent from its closest rival, the Cambridge Audio CXA81 MKII, which counters with a USB input.

If your budget fits, listen to the A15—it’s tough to find a better-sounding amplifier at this price.

2. Rotel A8 – Best Entry-Level Stereo Amplifier

What Hi-Fi? Award winner. A modest yet remarkably capable integrated amplifier setting the standard at this accessible level.

Pros:

• Clean, controlled, and precise sound
• Expressive dynamics and powerful bass
• Phono input for vinyl players

Cons:

• No Bluetooth or digital connectivity

This year, Rotel’s A8 has pushed aside the long-time favorite Marantz PM6007 as our top budget pick. It combines excellent build quality with sound that sets the bar for its price, reminiscent of Rotel’s award-winning early 2000s budget models.

While it lacks Bluetooth and digital inputs, these can be supplemented by an external streamer or Bluetooth receiver without sacrificing sound quality. The A8 outperforms the Marantz PM6007 in clarity and detail retrieval, "melting into the background to let the music and other components shine.”

Other budget alternatives include the five-star Cambridge Audio AXA35 or the slightly pricier Mission 778X, if you want Bluetooth and USB.

3. Arcam A5 – Best Budget Stereo Amplifier

What Hi-Fi? Award winner. You won’t find a more musical and versatile amplifier at this affordable level.

Pros:

• Impressively insightful, articulate, and engaging sound
• Friendly character
• Good feature set

Cons:

• Display lacks absolute sharpness
• No USB input

Once dominant in the affordable stereo market, Arcam’s presence waned in recent years. But the new A5 revitalizes their standing with a fresh design and modern appeal, delivering stunning value for the money.

The A5 handles both budget and premium sources well, balancing forgiveness for lesser components with the transparency to highlight better ones. Our reviewers praised its full-bodied, smooth sound that never drains music of life, controlled even during dense passages, with clear and authoritative bass.

Vinyl lovers will appreciate the clean, expressive phono stage, and the DAC quality on coaxial and optical inputs is satisfying.

If you’re shopping at this level, the A5 deserves top billing on your list.

"It has a pleasant character that, while full-bodied and smooth, never goes so far as to deprive music of life." – Expert Reviewers

4. Rega Elex Mk4 – Best Mid-Range Stereo Amplifier

Still engaging and detailed, now with digital connectivity.

Pros:

• Surprisingly detailed sound
• Excellent timing and flexibility

The successor to the award-winning Rega Elex-R, this model impresses with sound quality surpassing expectations for mid-tier gear (starting around $1,900). Its elegant and confident musicality is rare in this range.

Reviewers noted the amplifier doesn't call attention to itself, allowing effortless enjoyment track after track. Digital inputs and headphone out add welcome versatility.

Pair it with speakers like the KEF LS50 Meta or Wharfedale Linton for a richer sound.

If your budget stretches, Rega’s Elicit MK5 offers a similar but even better option, slightly pricier, and a solid alternative to the Naim Nait XS 3.

5. Cyrus 40 AMP – Best Premium Stereo Amplifier

Fully equipped, superbly built, and sounding excellent—our top versatile pick in the high-end segment.

Pros:

• Clean, detailed, musical performance
• Expressive dynamics
• Upgrade options
• Great new look

Cons:

• Optional 40 PSU power supply is effective but costly

Cyrus’s new 40 series marks a fresh start with a sleek, modern design: matte anodized aluminum and glass front panel, half-width chassis.

It features all expected modern inputs, including USB and HDMI eARC for AV integration, plus a phono input.

The star is its sound quality—clean, articulate, balanced, and confident with all types of music. The tonal character is neutral and refined, balancing analytical clarity with musical enjoyment better than most rivals.

The digital section shines, preserving dynamic and rhythmic qualities alongside the analog stages.

Performance-wise, the 40 AMP sits atop this category. Alternatives include the Rega Aethos (without digital inputs) or higher-budget options like Naim Supernait 3, Rotel Michi X3, and Cambridge Audio Edge A.

6. Naim Nait XS 3 – Best for Purists

What Hi-Fi? Award winner. The third-generation analog Nait continues its legacy, now better than ever.

Pros:

• Dynamic, detailed, musical sound
• Decent MM phono stage
• Upgrade path available

Cons:

• No digital inputs or Bluetooth

This third iteration of a model first launched in 2008 adds a MM phono stage and improves responsiveness. It’s a powerhouse in sound quality (price starting near $4,000).

The advanced engineering reduces interference and optimizes internal layouts, resulting in clearer, livelier sound than its predecessor.

The phono stage defies usual budget limitations with detail and energy, while the amp delivers a compelling blend of insight, dynamic finesse, and rhythmic drive.

Ultimately, the XS 3 preserves music’s emotional impact brilliantly.

7. Lavardin ITx – Best High-End Stereo Amplifier

A subtle choice but a wonderful musical performer in the right system.

Pros:

• Amazingly musical, insightful, and uncluttered delivery
• Flawless rhythm handling
• Expressive dynamics

Cons:

• Poor quality remote, sold separately
• Requires careful component matching
• Limited connectivity

Lavardin ITx is one of the most straightforward and humble amplifiers heard. Its sound isn’t warm or rich like some tube amps but is incredibly sweet, fast, smooth, and precise without clinical sterility.

It offers a stunningly wide, precise, and richly textured stereo image, focusing on music itself rather than Hi-Fi nitpicking.

Connectivity is minimal—four unbalanced line inputs and one record output—so vinyl or headphone users should budget for external phono and headphone amps.

For more budget, Luxman L-509Z and Copland CSA 100 are excellent alternatives, while Gryphon Audio Diablo 333 and Esoteric F-01/PS-01F cater to ultra high-end needs over $20,000.

8. Chord Anni – Best Desktop Stereo Amplifier

An analog desktop marvel perfect for small systems.

Pros:

• Detailed, dynamic, musical sound
• Pleasant sonic stability
• Excellent build quality

Cons:

• Only two analog inputs
• Ergonomics could improve
• Gets quite warm

Chord Electronics’ miniature desktop amp Anni is a real gem, employing Ultima circuit tech from their flagship amps but in ultra-compact form—no bigger than their Qutest DAC.

Though capable of driving larger speakers, its 10W per channel power is best suited for desktops or headphones.

Despite limited inputs, it delivers a rich and energetic soundstage exceeding expectations for its size.

For a more affordable but similarly sized alternative, check out the NAD D 3020 V2.

9. Naim Uniti Atom – Best Streaming Stereo Amplifier

What Hi-Fi? Award winner. Stunning streamer and amplifier all-in-one—just add speakers.

Pros:

• Generous streaming features
• Best-in-class clarity and insight
• Excellent timing and dynamic range
• Looks as good as it sounds

Cons:

• No phono input

If you want network streaming without adding more boxes cluttering your rack, a streaming amplifier is your answer. The Naim Uniti Atom remains a benchmark nearly eight years in, continually updated with new streaming capabilities.

It offers Naim’s signature sound with extensive streaming options: DLNA, Google Chromecast, Tidal Connect, Spotify Connect, internet radio, AirPlay, and aptX HD Bluetooth.

Inputs allow connection of other sources like CD players but lack a phono stage.

Alternatives include Cambridge Evo 150 (with phono), Moon Neo Ace, Ruark R610, and Technics SA-C600 (with CD player integration).

Also Consider

• Rega io. Fun, affordable amplifier without digital inputs but highly engaging sound.
• Rega Brio MK7. A mid-range classic rival to Arcam A5, now with DAC and digital inputs.
• Marantz PM6007. Still recommended entry-level amp with digital inputs.
• Naim Supernait 3. Enhanced alternative to Rega Aethos with phono stage, dynamic sound.
• Luxman L-509Z. High-end alternative offering ambitious performance and features.
• PMC Cor. Balanced analog amplifier used in test reference rooms, musically excellent.
• Copland CTA407. The only integrated tube amplifier here, highly recommended for careful pairing.
• Ruark R610. More affordable streaming amp competing with Naim Uniti Atom.

How to Choose the Best Stereo Amplifier for You

What Sources Do You Need?

Start by considering your audio sources and how you'll connect them. Stereo amplifiers today are far from the analog-only boxes of old. Many now include built-in DACs for digital inputs to connect laptops, hard drives, or digital Hi-Fi sources conveniently.

Not all digital sections match the quality of analog, so higher-end systems might benefit from separate DACs paired with pure analog amps.

The vinyl revival means many amps now feature phono stages. Some have Bluetooth for wireless ease; others offer Wi-Fi and Ethernet with full streaming systems (“just add speakers” setups).

Your choice depends on your current equipment and how you plan to integrate everything.

Consider Amplifier & Speaker Synergy

The amp-speaker partnership matters beyond power output. Speaker impedance, sensitivity, and tonal characteristics all influence synergy. Choosing compatible components ensures the best sound harmony.

Frequently Asked Questions

• Is it better to buy an integrated amplifier or separate preamp and power amp?
  Integrated amps combine preamp and power amp in one box, reducing clutter and ensuring matched circuitry. Separate units can offer better noise isolation and potentially improved sound but at higher cost and complexity.
• Do I need digital inputs on my stereo amplifier?
  If your sources are digital (CD, streaming), either your source or amp needs a DAC. Often, source DACs outperform amp DACs, so digital inputs on amps are convenient but not mandatory.
• Are stereo amplifiers with HDMI common?
  HDMI ARC ports are rare on stereo amps, more common on AV receivers. Some amps include HDMI for TV audio integration, a neat feature for those wanting better TV sound through stereo systems.
• What’s the difference between a stereo amplifier and a stereo receiver?
  Receivers typically include built-in radio tuners (FM/AM/DAB), allowing direct radio playback. Amplifiers lack this but focus purely on audio amplification. Receivers are less common nowadays due to streaming and internet radio.
• How important is amplifier and speaker matching?
  Very important. Power, impedance, sensitivity, and tonal balance all affect how well an amp and speakers work together. Proper matching yields the best sound quality and system performance.
