Unitra WSH-805 Integrated Amplifier

Unitra WSH-805 represents a refined approach to integrated amplification, drawing aesthetic and sonic inspiration from vintage audio design. Built on dual-mono architecture with current feedback topology, this amplifier delivers exceptional channel separation and transparent sound reproduction across a fully analog signal path. The dual-class operation provides flexibility for different listening preferences, while comprehensive input options—including balanced XLR connections—accommodate various source components. Distinctive swing-out meters and automatic switching technology complete a design that balances nostalgic appeal with genuine engineering sophistication.

Timeless Interface

The interface using pivot indicators and bistable switches in a new iteration in our patented automated version - an unmistakable beauty with added functionality and convenience.

All-analog stereo integrated amplifier 

Inspired by the golden era of analog stereo of the 1970s, we created it anew, improving everything that could be used with modern advances , but leaving the main concepts. That's why the WSH-805 is fully analog, with no digital signal processing elements that can interfere with the original sound of the original analog signal. The result is the closest amplifier to the original sound, which in its essence is analog.

Dual-mono Architecture

Each channel uses a separate preamplifier and power amplifier to ensure the best possible channel separation.

Current Feedback Topology

While being more challenging to implement, this topology offers improved performance in terms of dynamic range and feedback.

Power block reinvented

A proprietary power block based on discrete circuits - a unique sound that differs significantly from that in devices based on "off the shelf" integrated circuits.

Changing the class of work

A unique feature of changing from Class A to Class AB operation with a dedicated switch on the front panel gives you the choice between maximum efficiency translating into loudness or maximum linearity of operation.

Traditional and balanced analog inputs

A rich set of RCA inputs, plus a pair of balanced XLR inputs for the most discerning analog audio enthusiasts, so they can connect the signal source in a way that minimizes the impact of interference from the source to the amplifier.

Phono preamplifier with cartridge type selection function

A dedicated phono preamplifier with a choice of MM or MC modes allows connection of any cartridge currently available on the market.

Built-in headphone amplifier

Dedicated low-impedance headphone amplifier allows you to connect Hi - End class headphones directly to the amplifier. Thanks to the optimally selected parameters, each pair of headphones plays in optimal conditions for each other.
