Halcro MC20 and MC50 Power Amplifier MC20 now sold, MC50 still available, price now reflects this Truly a modern classic, designed in Australia. Crystal clear sound and massive power and dynamics will suit any duty from critical listening to fully immersive HT. In Australia, they are a definite bargain. TBH, not sure why I am selling. I always seem to go back to Halcro, but too attached to my other amps and need some space. Comes with original double boxes and packaging so shipping is theoretically possible, but much prefer local pickup. Power Output: 350W RMS continuous into 4 O
Buyer’s market for this class of used gear, and A$2,200 for a Halcro MC20 looks fair to slightly attractive versus the recent comparable listings anchor: the middle of the pack is A$2,409, with a typical spread from A$2,032 to A$2,786. If the amp is genuine, clean, and fully functional, this sits a bit below the median without being a giveaway.
Before buying, verify it powers up cleanly with no relay chatter, offset issues, or channel imbalance, and ask about any history of board or PSU repair. Halcro pieces can be worth the premium only if they’re pristine and original, so confirm the serial, cosmetic condition, and that you’re getting the correct power cord, manual, and any factory accessories.
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.
