At A$2,400, this retro-thermionic ArmaDillo Power Amplifier is ambitious, sitting well above the 75th percentile of A$1,932 for comparable used AUD listings and far exceeding the median of A$200. While third-party amplifiers featuring high-end Mundorf parts often retail between A$3,000 and A$12,000 new, this specific listing’s price is steep relative to the immediate used market anchor you provided.
The appeal lies in the unique “retro-thermionic” tube topology combined with Mundorf’s premium capacitors, which typically deliver rich harmonic detail and tight bass control favored by vintage enthusiasts. If this unit is original-owner condition with included tubes and accessories, the rarity of a fully built ArmaDillo with these components could justify the premium for a collector seeking a distinctive sound. However, given the price exceeds the 75th percentile, verify the condition thoroughly and confirm what’s included before committing.

Mundorf traces its roots to 1985 in Cologne, Germany, where Raimund Mundorf launched the company with a passion for hi-fi sparked in his childhood. Initially focused on high-quality crossover components for enthusiasts, it evolved from his hands-on engineering amid the Rhine region's audio heritage. Over four decades, Mundorf has grown into a global benchmark, manufacturing at its headquarters with unwavering commitment to precision craftsmanship.
The brand specializes in premium passive audio components, renowned for capacitors like the MCap, Supreme, and EVO series, alongside inductors, air-core coils such as the MCoil, and high-end NF and speaker cables.
