1,586 components. Not one of them digital.

Dual-mono from the power supply to the output stage. 100% analogue — nothing simulated, nothing converted.

Typ WSH-805 Zakład Warszawa

Every surface is what it claims to be.

The front panel is solid brushed aluminium, thicker than the chassis beneath it. The volume control is a motorized aluminium potentiometer, turned by hand or by remote. The meters swing because there is a movement behind them. Every surface on the WSH-805 is the material it appears to be, and every control does the job its shape suggests. That is the whole difference between a revival and a costume.
Front panel Thin stamped aluminium, printed to suggest weight Solid brushed aluminium, thicker than the chassis it sits on
Volume control Digital encoder, dressed as a dial Motorized aluminium potentiometer — a mechanical dial, not a simulation of one
Channel architecture Shared power supply, one board doing both jobs True dual-mono — independent left and right, power supply to output
Signal path Digitally assisted, correction applied after the fact 100% analogue — nothing in the path is simulated
Inputs A pair of RCA jacks, a converter doing the rest Seven RCA and one balanced XLR — eight ways in, all of them analogue

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

Watts, Distortion and Inputs

Nothing simulated. Nothing converted.

125W

Class AB power into 4Ω — with a Class A mode underneath for the first ~10W, before it ever needs to work hard.

0.0008%

Total harmonic distortion at 40W — current-feedback topology, not digital correction, gets it there.

8

Analogue inputs — seven RCA plus one balanced XLR. Every one of them stays analogue, start to finish.

Where is the WSH-805 made?
Unitra Audio builds the WSH-805 in Europe, continuing an engineering tradition that dates back to 1961 and has made the Unitra name respected across the continent's hi-fi manufacturing.
Is the WSH-805 a fully analogue amplifier?
Yes, fully. There's no DSP anywhere in the signal path — volume is a motorized aluminium potentiometer, not a digital control pretending to be one.
What inputs does it have?
Eight, all analogue: seven RCA — including a switchable MM/MC phono stage — plus one balanced XLR. No digital or Bluetooth inputs; every source stays analogue end to end.
What's the front panel and volume control made from?
A brushed aluminium front panel — deliberately thicker than the chassis it's mounted to — paired with a motorized aluminium volume dial and illuminated VU meters.
Is this a restored vintage unit or a new build?
A new build. The WSH-805 Classic Edition is engineered today, using the golden age of hi-fi as the design brief — not a refurbished original.
Does it run in Class A or Class AB?
Both — switchable. Class A gives you the first ~10 W in its purest form; Class AB takes over for full-range dynamics, delivering 80 W into 8 Ω or 125 W into 4 Ω.
About the Unitra WSH-805 Classic Edition Integrated Amplifier - Dual-Mono Hi-Fi

The Golden Age of Hi-Fi, Reimagined

The Unitra WSH-805 Classic Edition Integrated Amplifier is a 100% analogue, dual-mono flagship integrated amplifier, engineered with 1,586 components and a current-feedback power stage. This is not a singing computer like so many modern products; it's a purist analogue amplifier with a brushed aluminium front panel, a motorized aluminium volume dial and illuminated VU meters. Available in classic silver or sophisticated black, it's a statement piece that delivers warmth, clarity and timeless style.

True Dual-Mono Architecture

At the heart of the WSH-805 Classic Edition is a dual-mono design — separate amplification channels for superior stereo separation and imaging. Keeping the left and right channels independent, from power supply through output, lets each speaker breathe on its own, opening up a wide, precisely focused soundstage. Switch between Class A for the first ~10 watts and Class AB for full-range dynamics — 80 W into 8 Ω, 125 W into 4 Ω — all on a fully analogue signal path.

Built to Be Seen and Heard

Every WSH-805 Classic Edition pairs a brushed aluminium front panel — deliberately thicker than the chassis it's mounted to — with a motorized aluminium volume dial, illuminated VU meters and eight fully analogue inputs: seven RCA (including a switchable MM/MC phono stage) plus one balanced XLR. Whether you're building a classic hi-fi system from scratch or adding a centrepiece to your listening room, this amplifier looks the part and plays it too.

Why You'll Love the WSH-805 Classic Edition

  • Switchable Class A / Class AB operation — 80 W @ 8Ω, 125 W @ 4Ω
  • Fully analogue, dual-mono signal path — no digital processing anywhere
  • Brushed aluminium front panel and motorized aluminium volume dial
  • Eight analogue inputs, including MM/MC phono and balanced XLR
  • Two finishes — classic silver or sophisticated black

Frequently Asked Questions

What does "dual-mono" mean?

It means the left and right channels have their own independent amplification stages, which improves stereo separation and imaging by keeping the two channels electrically isolated from each other.

Is this a digital or analogue amplifier?

Fully analogue. The WSH-805 Classic Edition is a purist, 100% analogue design with no digital processing in the signal path.

What finishes are available?

Two: classic silver or sophisticated black.
