IA-60

• Positioning: An entry-level integrated amplifier designed for limited budgets.
• Description: Features a modern take on classic analog design with a simple yet effective low-noise gain stage that keeps costs down. Compared to the IA-180 and IA-400, its technology is more basic while still offering clear sound for small rooms and modest functionality needs.

PW-250

• Positioning: A compact stereo power amplifier offering efficient class D performance at an affordable rate.
• Description: Uses class D modules that deliver dynamic and transparent sound in a small package without unnecessary extras. Compared to the PW-400, its design is simpler.

IA-180

• Positioning: A mid-range integrated amplifier balancing performance with moderate pricing.
• Description: Incorporates refined class D power modules and a well-controlled preamplifier section to improve clarity and stability. Compared to the IA-60 and IA-400, it offers a noticeable upgrade in detail and functionality.

PW-400

• Positioning: A higher-tier stereo power amplifier engineered for modern speakers and larger setups.
• Description: Pushes class D technology further with special voltage regulators and precise control circuitry to enhance detail and overall transparency. Compared to the PW-250, its advanced power stage and output capabilities provide extra power and clearer sound in bigger environments.

IA-400

• Positioning: A high-end integrated amplifier built for demanding audio systems and premium performance.
• Description: Uses a sophisticated layout with dedicated power transformer and relay input switching for minimal noise and accurate signal reproduction. Compared to the IA-60 and IA-180, its advanced design and robust power output serve users with high standards and larger rooms.
