TransAudio The third-generation pure post amplifier T5PRO with original parameters

Core Circuit

Adopts a fully symmetrical X-Amp ultra-fast power amplification circuit.

No audio input capacitor or decoupling capacitor. It features a pure DC design with extended high and low frequency response. Reference model: Burmester 956.

Boasts outstanding control capability. Equipped with a high damping factor, the unit delivers strong driving force and can easily drive the vast majority of mid-sized loudspeakers.

It offers high resolution with balanced and transparent treble, midrange and bass, making it a rare Hi-Fi gem.

It presents the meticulous sound signature of German Burmester: high resolution and first-class control.

This amplifier excels remarkably in low-frequency performance, delivering exceptional bass control, volume and resolution.

Materials & Construction

Premium 800W Nippon Steel toroidal transformer: vibration-free and silent, wound with pure copper wire to ensure low voltage drop.

Built-in power-on soft-start circuit and comprehensive speaker protection.

4 pairs of precisely matched Sanken power transistors C2922/A1216, with 2 pairs per channel, generating powerful thrust enough to drive all floor-standing loudspeakers.

Each channel is fitted with 6 audio-dedicated electrolytic capacitors for a total capacity of 120,000 F, creating a large energy reservoir.

Fully independent left and right channel design to reduce crosstalk.

CNC-machined 430mm standard full-aluminum chassis.

All complete amplifiers and finished circuit boards sold in our store are welded using American ALPHA solder wire, which ensures stable welding quality,

 low internal resistance, bright solder joints and strong oxidation resistance.

The output stage adopts a Class A high quiescent current design with 100mA for each transistor pair, rendering warm and pleasant sound.

High-performance binding posts and input RCA sockets for superior sound reproduction.
