One Path, Three Sources

Typ WSH-605 Zakład Warszawa

Designed in, not bolted on

Whether the phono stage was designed in or bolted on; whether the DAC is core circuitry or a marketing sticker — a feature list will not answer either question. The WSH-605 routes vinyl, streaming and digital sources through one disciplined signal path, not three competing ones. Every input on the back panel earns its place on the front panel's selector.

Power stage Cost-shaved Class D module chasing a headline wattage figure Discrete Class AB output stage with error-correction circuitry, rated 70 W/8Ω, 110 W/4Ω

Digital conversion Bundled generic DAC chip treated as a checkbox feature ESS Sabre DAC with dedicated jitter-reduction, fed by dual coaxial and dual optical inputs

Phono handling Phono input omitted, pushing buyers to an outboard preamp Built-in MM phono stage wired straight into the same signal path as the digital inputs

Chassis and fascia Plastic wrap over a stamped steel shell Metal chassis with a brushed aluminium front panel and precision volume, balance and tone knobs

Headphone output Afterthought jack tapped off the speaker line Dedicated headphone amplifier stage feeding a 6.3 mm output, independent of the speaker taps

A genuine MM stage, designed into the amplifier

108.8 dB below signal, with 70 W per channel on tap

The combine, 1961-1989

More than sixty enterprises carried the Unitra name until 1989. These five are the works whose specialities the record actually states.

Watts and the Noise Floor

Seventy watts, and how quiet it stays

70W / 8Ω

Class AB power per channel, rising to 110 W into 4-ohm loads for harder-to-drive speakers.

108.8dB S/N

A noise floor low enough that the amplifier, not the source, sets the ceiling on quiet passages.

0.0013% THD

Measured at 1 W, 1 kHz — distortion low enough to stay out of the way of the music.

How many watts does the Unitra WSH-605 put out?

70 W RMS per channel into 8-ohm speakers, Class AB, rising to 110 W into 4-ohm loads. That's enough headroom for most stand-mount and floorstanding speakers in a domestic room.

Does the WSH-605 have a phono input for turntables?

Yes. It includes a built-in phono stage for moving-magnet (MM) cartridges, plus a dedicated ground terminal, so a turntable can be connected directly without an outboard phono preamp.

What digital inputs does it support?

Two coaxial and two optical digital inputs, run through a built-in ESS Sabre DAC with jitter-reduction and error-correction technology, alongside analogue AUX, Tuner, Streamer and CD inputs.

Can I use it with headphones?

Yes, there's a dedicated 6.3 mm headphone output driven by its own headphone amplifier stage, separate from the speaker outputs.

What are the dimensions and weight?

440 mm wide x 104 mm high x 372 mm deep, weighing 12 kg — a standard full-width integrated amplifier footprint.

What speaker cable is recommended for the WSH-605?

Any well-made speaker cable suits it; Unitra's own KG-25 or KG-40 speaker cables are matched to the amplifier's binding posts and gauge for a straightforward, tidy connection.

About the Unitra WSH-605 Integrated Amplifier

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.
