# Halcro MC20 – A$1,500
The Halcro MC20 is a compact, high-current Class AB amplifier that punches well above its size—it's built like a tank and remains sought-after on the used market. At A$1,500, this asking price sits comfortably below the median comparable of A$2,409 from recent listings, placing it near the 25th percentile threshold of A$2,032. That's a genuine bargain if the unit is in working order, though the "unknown" condition flag is a red flag that demands immediate clarification.
Before committing, confirm the amp powers up cleanly with no hum, hiss, or channel imbalance at idle and under load. Check that both channels deliver stable output across the frequency range—these amps are robust, but aging capacitors can drift. Verify all connectors are present (balanced XLR in, speaker posts), and ask whether it's been serviced or recapped recently. If it hasn't been touched in five-plus years, factor in potential service costs, which could easily exceed A$400–600 for a thorough recap.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Halcro emerged in the late 1990s as an Australian hi-fi innovator, founded by physicist and inventor Bruce Candy, who also established Minelab Electronics in metal detection. Launched as a Minelab subsidiary, the brand quickly disrupted the market with its debut dm58 monoblock amplifiers, boasting distortion levels in parts per billion—specifications that challenged even the finest measurement gear. Stereophile crowned the dm58 "The Best Amplifier Ever" in a 2002 cover story, cementing Halcro's early legacy amid corporate shifts, including a brief licensing deal with Vivid Audio that faltered during the Global Financial Crisis.
The brand specializes in high-end solid-state power amplifiers, renowned for their patented topologies, power factor corrected supplies, and H-shaped chassis designs that prioritize thermal efficiency and sonic purity. Holding five international patents, Halcro's products deliver near-perfect signal integrity—up to 99.9996% purity in flagships like the dm58—while eschewing speakers, DACs, or headphones in favor of amplification excellence. Recent revivals under Longwood Audio since 2014 have sustained this focus, now paired with re-emerging Australian marques like Duntech.
Positioned firmly in the ultra-high-end niche, Halcro commands reverence among discerning audiophiles for its objective technical supremacy and subjective musicality, often adopted by elite brands like Wilson Audio for show demonstrations. Though production lapsed for years, its resurgence channels fresh expertise from physicists, engineers, and musicians, reminding buyers why it remains a boutique benchmark for those seeking vanishingly low distortion and uncolored transparency in a crowded market.
