Balanced Class D performance

The Cattle Pro is a high-performance Class D power amplifier designed for clarity, precision, and the freedom to fine-tune your listening room. Its low noise floor, transparent signal handling, and careful component selection create an exciting listening session that remains thrilling even as the hours pass. 

Let the music flow with wide soundstage

A balanced sound field can make a living space feel more open—wider instrument placement, layered depth, and a sense of breathing room. 

Two RCA inputs for flexible source control

With multiple RCA inputs, connect a turntable and a DAC or an audio streamer and a CD player. No complicated steps—just press the button and the Cattle Pro switches between sources. 

Sub-out to fill the low-end

When a track calls for more bass, connect an active subwoofer to the dedicated Sub-Out. 

TPA3255 chip and Rubycon components

The carefully chosen TPA3255 chip generates precise output up to 2×200W. Complemented by a professional-grade Rubycon operational amplifier chip, the result is a foundation that never feels strained, even at higher volumes.

Oversized radiator for stable performance

Pushing higher wattage can build heat. An oversized radiator helps manage that. It keeps the amplifier’s internals cooler—especially when playlists stretch long into the evening—so the sound can maintain its integrity.

Thoughtful circuit design and power isolation

A digital-analog isolated power supply reduces unwanted interference, maintaining a signal path that stays clean and allows subtle details to emerge without static or hum.

Protection that takes care of itself

The amplifier monitors its own condition—overheating and overcurrent protection help to keep listening sessions safe and worry-free.
