The Heart and Brain of Your System

The Unitra WSH-605 Integrated Amplifier is built for listeners who want a single component to be both the heart and the brain of their setup. Delivering up to a powerful 110 watts per channel in refined Class AB, it pairs muscular drive with a naturally expressive sound signature. A comprehensive input array spans analog and digital, complete with a dedicated phono stage for vinyl and an on-board ESS Sabre DAC — so the WSH-605 doesn't just amplify, it perfects.

110 Watts of Refined Class AB

Crafted in Europe to meticulous engineering standards, the WSH-605 uses sophisticated error-correction circuitry, exceptionally low harmonic distortion and a high damping factor to deliver control, accuracy and effortless dynamics. The numbers tell the story: THD of just 0.0013% at 1W/1kHz, a signal-to-noise ratio of 108.8 dB, and channel separation better than 75 dB. This is amplification engineered for transparency as much as power.

Every Source Covered — Plus On-Board DAC and Phono

A dedicated phono stage welcomes turntables, while the integrated ESS Sabre DAC brings digital sources to life with clarity and precision. Bass, treble and balance controls — plus a linear tone-bypass mode — let you tailor the sound or hear it perfectly flat. A modular design philosophy ensures long-term reliability and upgradeability, so the WSH-605 is built to stay at the centre of your system for years.

Frequently Asked Questions

Does the WSH-605 have a built-in DAC and phono stage?

Yes — both. An on-board ESS Sabre DAC handles digital sources, and a dedicated phono stage is included for turntables, so you can connect analog and digital sources directly.

How much power does it deliver?

Up to 110 watts per channel in Class AB, with a high damping factor for tight control over your loudspeakers.

Can I bypass the tone controls?

Yes. A linear (tone-control bypass) mode lets you hear the signal perfectly flat, alongside bass, treble and balance adjustment when you want it.
