Best Stereo Amplifiers: Entry and Mid-Tier Level – PART II

Part I of this guide is available at this link. In this second half, we cover the remaining six amplifiers in the premium tier, comprehensive comparison charts, speaker matching, system-building recommendations, and the verdict.

Tier 3: $1,200-$2,500

Hegel H95

$2,000 | 60W into 8 ohms, 120W into 4 ohms | Class AB with SoundEngine 2

The Hegel H95 offers only 60 W per channel - but the proprietary SoundEngine 2 analog error-correction topology, which continuously compares the input signal against the output at every gain stage and eliminates any discrepancy, works with exceptional effectiveness. For transparency, dynamic agility, and neutrality, few amplifiers at any price come close. A damping factor of 2,000 allows the H95 to drive even very demanding loudspeakers without difficulty, and full streaming capability - AirPlay, Spotify Connect, and UPnP - is built in as standard.

Musical Fidelity M3si

$1,599 | 85W into 8 ohms | Class AB

The Musical Fidelity M3si is a purist design - no streaming, but a 24-bit/96 kHz DAC is on board. The 85 W per channel output figure looks modest on paper, but the dual-mono architecture with proprietary SMD layout delivers a sound that is sweeping, powerful, and genuinely commanding. The amplifier seizes control of loudspeakers with an iron grip and extracts every last capability from them. A superb built-in phono stage completes the picture.

Cambridge Audio CXA81

$1,499 | 80W into 8 ohms, 120W into 4 ohms | Class AB

The Cambridge Audio CXA81 employs a dual-mono circuit topology, an ESS Sabre ES9016K2M DAC with support up to 32-bit/384 kHz and DSD256, and a balanced input. The sound carries a refinement and an elusive grace not present at lower price points - set against excellent frequency-range resolution across the entire spectrum, the result is a presentation that can be listened to for hours without a trace of fatigue. Soundstage construction remains the amplifier's traditional strong suit.

Arcam SA30

$2,499 | 90W into 8 ohms | Class G with Dirac Live

The Arcam SA30 operates in Class G at 90 W per channel and incorporates Dirac Live room correction. This means a complete system built around it can be successfully deployed even in acoustically problematic spaces - correcting room-induced issues in the digital domain. Class G amplification adjusts the supply voltage dynamically according to signal level, delivering the efficiency benefits of Class D with a sonic character closer to Class AB. Streaming capability includes Google Chromecast, AirPlay 2, Spotify Connect, and Roon compatibility. The sonic presentation is balanced and clean, with particularly refined midrange reproduction.

Exposure 3510

$2,999 | 110W into 8 ohms | Class AB

The Exposure 3510 uses bipolar output transistors (Toshiba 2SA1943 and 2SC5200) throughout, with a circuit topology built around an ultra-short signal path and individually selected audiophile-grade components. There is no streaming, no DAC, no wireless module - only 110 W per channel of amplification, executed with singular focus. The sound is crystalline in its purity and conveys the full richness of tonal colour with precision. The sense of presence the Exposure achieves is simply outstanding.

The Verdict: Which Amplifier Should You Buy?

Problematic room: The Arcam SA30 ($2,499) with Dirac Live.

First Hi-Fi system: The Cambridge Audio AXA35 ($349) or Yamaha A-S301 ($449).

Difficult speakers: The Rotel RA-1572 MKII ($1,299).

Vinyl lover: The Marantz PM8006 ($1,199).

All digital: The NAD C368 with BluOS ($1,198) or the Hegel H95 ($2,000).
