T+A Amplifiers

A 200

Effortless power, refined control.

The A 200 is a stereo power amplifier from T+A's Series 200 that combines an HV-derived high-voltage input stage with PURIFI Eigentakt Class D output modules. The result is 2 × 180 W into 8 ohms (250 W into 4 ohms) with exceptional damping, ultra-low distortion, and an adjustable damping factor that lets you fine-tune speaker control to your preference. An HF Sine-Wave power supply ensures rock-solid rail stability under dynamic loads.

Key Features

HV-Derived Input Stage

The input section borrows high-voltage topology from the flagship HV series, operating at elevated rail voltages for maximum linearity and headroom.

PURIFI Eigentakt Output

Class D power stage delivers 2 × 180 W / 8 Ω (250 W / 4 Ω) with distortion figures rivalling the best Class A/B designs — and virtually no heat.

Adjustable Damping Factor

User-selectable damping factor lets you match amplifier behaviour to your loudspeakers — from tight, authoritative bass to a more relaxed, open character.

HF Sine-Wave Power Supply

Proprietary switch-mode supply with sine-wave switching eliminates high-frequency interference while delivering instant current reserves.

Technologies Inside

High Voltage Technology

Tube linearity. Transistor power.

T+A's HV amplifiers operate at dramatically higher voltages than conventional designs — up to 100V in preamplifiers and 360V in power amplifiers. This forces the audio signal to exercise less than 20% of each transistor's operating curve, staying in the most linear region. The result is tube-like linearity and naturalness with transistor power, bandwidth, and reliability — virtually no negative feedback required. Built entirely from discrete components with individually selected audio J-FET transistors, encapsulated gold-contact relays, and precision discrete resistor volume control.

Most solid-state amplifiers operate their transistors across a wide portion of their transfer characteristic, which introduces non-linearity that must be corrected with large amounts of negative feedback — a technique that reduces distortion on paper but can compress dynamics and add its own sonic signature. T+A's approach is fundamentally different: by raising the supply voltage to 360V in power amplifiers (compared to the typical 60–80V), the music signal uses only the most linear 20% of each transistor's operating curve — the region where a transistor behaves almost identically to a vacuum tube. This means negative feedback can be reduced to near-zero levels, preserving the signal's original dynamics, micro-detail, and spatial information. Every HV circuit is built from discrete components rather than integrated circuits: individually selected and matched audio-grade J-FET transistors, hermetically sealed gold-contact relays for signal switching, and a precision discrete resistor ladder for volume control that maintains perfect channel balance and signal purity at every level.

HF Sine-Wave Power Supply

Clean power. 100,000 recharges per second.

T+A's High-Frequency Sine-Wave power supply generates a pure sine-wave output at more than twice the frequency of conventional mains sections, eradicating the interference that switching supplies produce. Custom-developed capacitors recharge 100,000 times per second — 2,000 times faster than conventional capacitors — providing absolutely constant voltage under severe loads.

Power supply design represents a fundamental compromise in audio: conventional linear supplies are clean but heavy and slow to respond to sudden current demands, while switching supplies are efficient and responsive but introduce high-frequency interference that can contaminate the audio signal. T+A's HF Sine-Wave supply sidesteps this dilemma entirely. Instead of the rectangular waveform used by standard switch-mode supplies (which is rich in harmonics that create audible interference), it generates a pure sine wave at a frequency more than double that of conventional mains supplies. This sine-wave output is inherently free of the sharp transients and harmonic content that make switching supplies problematic in audio applications. The custom-developed capacitors, recharging 100,000 times per second, maintain virtually constant voltage even under the most severe dynamic demands — when a powerful amplifier suddenly needs high current for a bass transient, the supply responds instantaneously without the voltage sag that colours the sound of conventional designs. The result combines the sonic purity of a linear supply with the efficiency, compact size, and dynamic capability of a switching design.

Series 200

Compact high-end. Modular by design.

Ultra-compact components with flagship-grade internals. The A 200 and M 200 power amplifiers combine an HV Class A input stage with PURIFI Eigentakt Class D output stages and T+A's HF Sine-Wave power supply — delivering extraordinary power from a remarkably small footprint. The modular T+A Link system connects multiple Series 200 units into a single integrated system.
