For the audio purist seeking uncompromising power, purity, and performance, the TONEWINNER AD-1PA+ stands as the flagship reference power amplifier. This is not an integrated amplifier; it is a dedicated, high-mass power plant designed for one purpose: to deliver limitless, clean, and dynamic current to the most demanding loudspeakers on the planet. Weighing in at over 90 pounds, its massive chassis and 5mm thick aluminum alloy panels house a level of engineering that prioritizes raw performance above all else.
The heart of the AD-1PA+ is its colossal 1200W toroidal transformer, shielded in an aluminum case and potted with epoxy resin to eliminate all mechanical vibration. This power supply feeds a gargantuan 180,000uF capacitor bank, ensuring an immense reserve of power that provides instantaneous dynamic response, effortless control, and a rock-solid, deep-black sonic background.
The true genius of the AD-1PA+ lies in its user-selectable amplification modes, allowing the listener to choose the perfect sonic character for their music.
- Pure Class A Mode: Engage this mode, and the AD-1PA+ delivers its first 100 watts per channel in pure Class A. This provides the legendary smoothness, warmth, and harmonic richness that Class A is famous for, rendering vocals and instruments with breathtaking realism and a complete absence of crossover distortion.
- Class AB Mode: When sheer dynamic headroom and power are required, switching to Class AB unleashes the amplifier’s full 300 watts per channel (at 8 Ohms). This mode delivers effortless grip and slam, controlling large speaker drivers with iron-fisted authority, perfect for complex orchestral passages or high-energy rock.
- Auto Mode: For ultimate convenience, the auto mode intelligently operates in Class A and seamlessly switches to Class AB only when the musical demands exceed the Class A threshold.
Its fully balanced, differential circuit topology, from the XLR inputs to the speaker outputs, ensures the cleanest possible signal path, rejecting noise and interference. Each channel is a fully independent monoblock module, featuring 12 high-power transistors for exceptional stability and low impedance drive.
The rear panel confirms its reference-level status, offering both balanced XLR and unbalanced RCA inputs, along with two sets of audiophile-grade, gold-plated speaker binding posts (A and B). This allows for easy bi-wiring of compatible speakers or for switching between two different pairs of loudspeakers, making the AD-1PA+ the definitive, no-compromise foundation for a state-of-the-art Hi-Fi system.
