Cyrus Audio 80 PWR

The Cyrus Audio 80 PWR is a dedicated power amplifier from the Cyrus 80 Series — delivering 200 watts per channel in class A/B configuration, with the option to bridge to mono and drive a single channel at 300 watts. Like the 80 AMP that precedes it in the range, the 80 PWR is built around the full-width Cyrus chassis — a format that allows a power supply of the scale and specification that serious amplification demands to be incorporated directly into the unit, without the need for an external PSU addition.

Full-Width Chassis and Integrated Power Supply

The shift to the full-width chassis is the engineering foundation upon which the entire 80 Series is built. In the half-width format, power supply capacity was a genuine constraint — one addressed through the addition of the Cyrus PSX-R2 external power supply. The 80 PWR resolves that constraint entirely by incorporating a power supply of appropriate scale within the chassis itself. The result is an amplifier that operates from its full potential without supplementary hardware — with the dynamic headroom, noise floor and authority that 200 watts of properly supplied class A/B amplification can deliver.

200 Watts Per Channel — and More

At 200 watts per channel into the standard load, the 80 PWR has the reserves to drive demanding loudspeakers with authority — loudspeakers that would expose the limitations of a less generously specified design under dynamic load. When bridged to mono, a single 80 PWR delivers 300 watts into a single channel. Two units operating in mono configuration create a monoblock power amplifier system of genuine high-end capability — an upgrade path that is available from the outset and can be pursued as the system evolves.

Partnership with the 80 PRE

The 80 PWR is designed to partner directly with the Cyrus 80 PRE preamplifier, forming a high-performance separates system at the summit of the 80 Series range. The combination of a dedicated preamplifier and power amplifier allows each stage to be optimised independently — the preamplifier for signal handling and source switching, the power amplifier for current delivery and loudspeaker control — without the compromises inherent in a combined integrated design. For those whose systems have grown beyond what an integrated amplifier can offer, the 80 PRE and 80 PWR represent the logical and most capable conclusion.

Class A/B Amplification

Cyrus's class A/B topology has been refined across four decades of amplifier development — prioritising timing accuracy, low distortion, and low-level resolution at every power level. The 80 PWR does not rely on headline wattage figures to justify its position in the range. At moderate listening levels, where most music is actually heard, it is the control, composure and low-level detail that set the 80 PWR apart. At high levels, the headroom available ensures that dynamic peaks are handled without strain or compression.

Technical Specifications

Who Is It For?

The 80 PWR is for the listener who has outgrown what an integrated amplifier can offer — or who is building a separates system from the outset and wants the best power amplifier the Cyrus 80 Series can provide. It suits those pairing it with the Cyrus 80 PRE as the output stage of a reference-level system, and those who want the option of monoblock operation as a future upgrade. Those already invested in the Cyrus Classic Series — with the Cyrus Classic AMP or Cyrus Classic Power — will find the 80 PWR a considerable step forward in authority and dynamic capability.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind. Dave and Chris can demonstrate the 80 PWR in our Norwich showroom — partnered with the 80 PRE, or as part of a wider 80 Series system — and can walk you through the monoblock upgrade path if that is a direction you are considering.
