High-Power Class AB Power Amplifier Based on Marantz HDAM Circuit

 

This amplifier is meticulously designed for audiophiles who understand the importance of accurate sound reproduction. Based on the legendary Japanese HDAM circuit (MP6005 model), this pure power amplifier delivers high-resolution, full-range audio. It's engineered to drive 99% of speakers with ease, from bookshelf to floorstanding models, providing stable, clean power for an immersive listening experience.

Key Features at a Glance:

  • ▶ Legendary HDAM-Inspired Circuit: The design references the classic HDAM circuit, renowned for its excellent resolution and full-frequency output. It delivers a pure, high-fidelity sound without the need for an external preamplifier for many sources.

  • ▶ 8 Imported Power Transistors: The Toshiba 2SA1943/2SC5200 transistors are rated for 15A/150W per pair. Our amplifier uses a total of 2 pairs per channel for a combined 350W, but we only utilize 150W of this total power for the actual output. This allows the power transistors to have significantly more headroom and space, which in turn further enhances the amplifier's safety and stability.

  • ▶ Dual-Mono Symmetrical Design: The internal layout features a perfectly mirrored dual-mono symmetrical design. This enhances channel separation and ensures perfect consistency between the left and right channels for a precise and stable soundstage.

  • ▶ Premium Audiophile Components:

    • Transformer: A pure copper, epoxy-sealed toroidal transformer provides robust and stable power for wide dynamic signals.

    • Capacitors: Two large 10,000uF imported filter capacitors ensure clean power storage and delivery.

  • ▶ Comprehensive Protection Circuits: Includes output relay protection, DC protection, overload protection, and short-circuit protection, safeguarding both the amplifier and your valuable speakers.

  • ▶ Excellent Thermal Design: The all-aluminum chassis features integrated oversized heatsinks, ensuring stable and reliable performance even during long listening sessions at high power.
