T+A PA 2000 R
The PA 2000 R is T+A's integrated amplifier from the R series — a design that carries the circuit topology of the company's HV series into a single chassis, built around fully discrete, op-amp-free construction from input to output.
Cascoded Differential Input Stage
The input stage uses a cascoded differential amplifier with hand-selected audio J-FET transistors — a topology drawn directly from T+A's HV series. There are no operational amplifiers anywhere in the signal path. The voltage amplifier and current amplifier stages are galvanically isolated from one another, which prevents loudspeaker currents from feeding back into the voltage amplification stage and eliminates the adverse effects of varying loudspeaker loads.
Output Stage and Power Supply
The output stages are designed for extreme linearity with very low negative feedback — a completely new development. Into 8 ohms the amplifier produces 100 watts per channel; that doubles to 200 watts into 4 ohms and reaches 300 watts into 2 ohms, with a slew rate of 60 V/µs. The power supply carries 60,000 µF of reservoir capacity, remaining stable under load without voltage collapse at high peak levels.
Relay-Switched Volume Control
Volume is handled by discrete precision resistors switched by bi-stable gold-contact relays, giving exact channel matching, the shortest possible signal paths, and elimination of noise and distortion. The relays are gas-tight, making them immune to contact degradation from corrosion, dust, or ageing.
Inputs, Outputs and System Integration
Three balanced XLR inputs and three high-level RCA inputs are provided. An optional phono module — available in MM or MC configuration — replaces one high-level input and offers 16 selectable capacitances (MM) or 16 selectable impedances (MC). Speaker connections are made via two pairs of gold-plated, non-magnetic pure brass terminals.
For system use, the PA 2000 R supports Surround Pass Through mode (triggered via an external signal), and connects to other R-series components via T+A's R2-Link control interface. A trigger input accepts +5V to +20V for remote power-on.

Who Is It For?
The PA 2000 R is for the serious audiophile who wants a single integrated chassis without conceding anything to a separate pre/power arrangement. It suits systems where the source quality is already high — partnered with a component such as the T+A DAC 200 or the T+A MP 200 — and where the loudspeaker load may be demanding. Those stepping up from the T+A PA 1100 E will find it a significant architectural step, and those considering separates might first compare it with the T+A PA 2500 R to understand where in the range they want to land.
