The Roksan Caspian M2 Power Amplifier takes a focused approach to system building. It can serve as a conventional stereo power amplifier with a separate preamplifier, but it is also designed to complement the Caspian M2 integrated amplifier in bi-amped or tri-amped installations. That dual role shapes the product: its front panel is deliberately simple, while the rear provides both RCA and XLR inputs, corresponding line outputs, and a selector for choosing the active connection. Inside, a 350 VA low-noise toroidal transformer supports a rated output of 85 watts per channel into 8 ohms and 125 watts per channel into 4 ohms. Combined with its low-rise stainless steel enclosure and UK manufacture, these details position the Caspian M2 as a dedicated amplifier for owners who value straightforward operation, robust construction, and room to expand a system over time.
Minimalist design with practical status information
At 432 mm wide, 80 mm high, and 330 mm deep, the Caspian M2 has the footprint of a conventional full-width hi-fi component but a notably low profile. Its stainless steel housing incorporates anti-vibration construction and gives the amplifier a substantial reported weight of 14 kg. The visual treatment is restrained and industrial rather than decorative, allowing it to sit naturally alongside other Caspian M2 components.
There are no conventional controls or buttons on the front panel. Instead, two LEDs—one for each channel—communicate standby and overload conditions through different colors. This preserves the uncluttered appearance while retaining useful channel-specific status information. The power switch is integrated into the underside of the amplifier, keeping it out of sight.
That arrangement makes sense for a power amplifier, where volume and source selection are normally handled elsewhere. It will particularly suit owners who prefer equipment that recedes visually once a system is configured. The trade-off is that anyone who wants prominent, immediately accessible controls may find the concealed power switch less convenient than a standard front-mounted design. Standby consumption is specified at 5 watts.
A substantial power supply in a slim enclosure
The Caspian M2 is built around a 350 VA low-noise toroidal transformer. This is a significant part of the amplifier’s design because the power supply must support both channels while responding to changing loudspeaker demands. Roksan rates the amplifier at 2 x 85 watts into 8 ohms, rising to 2 x 125 watts into 4 ohms.
The increase in rated output as impedance falls is useful system-matching information. It indicates that the amplifier is specified to deliver more power into a 4-ohm load rather than being limited to speakers with a nominal 8-ohm rating. As always, nominal impedance alone does not describe every demand a loudspeaker may place on an amplifier, but the two ratings provide prospective owners with a clearer basis for matching components.
Other published figures include a damping factor of 160 into 8 ohms, gain of 31.6 dB, input sensitivity of 240 mV, and input impedance of 38 kilohms. The stated signal-to-noise ratio is 100 dB at 900 mV, while harmonic distortion is listed as less than 0.005 percent at 1 kHz into 8 ohms. These specifications describe a circuit intended to combine useful power with low measured distortion and noise; they should not, by themselves, be treated as substitutes for evaluating compatibility across an entire system.
Wide-band circuit specification
The amplifier’s stated frequency range extends from 3 Hz to 100 kHz at the minus-3 dB points. That range reaches well beyond the conventional audible band at both ends. Its relevance is not that a listener needs ultrasonic program content, but that the amplifier has been designed with broad operating bandwidth rather than a sharply restricted response window.
The source information also identifies carefully considered circuit topology and the use of high-quality components. While those broad descriptions do not reveal the complete internal architecture, they align with the amplifier’s dedicated purpose: this is not an integrated unit crowded with source selection, volume control, digital conversion, or streaming hardware. Its job is power amplification, leaving control and source duties to separate components.
RCA and XLR connectivity
The Caspian M2 accommodates both line-level RCA and balanced XLR connections. A slide switch on the rear panel selects which input is active. This gives owners a practical choice when matching the amplifier with a preamplifier, integrated amplifier, or other suitable line-level source component.
The presence of XLR sockets is especially useful in systems already built around balanced connections, while RCA maintains compatibility with the more common single-ended interface. The provision of both does not require an owner to commit to one cable format when planning future system changes. Input selection is performed manually at the rear, so the amplifier is designed for a stable installation rather than frequent switching between two connected sources.
A ground terminal is also included. Speaker connections are handled by four screw terminals, providing the standard positive and negative connection points for the amplifier’s two channels. This straightforward terminal arrangement is consistent with its role as a two-channel power amplifier.
Designed to support bi-amping and tri-amping
The most distinctive aspect of the Caspian M2’s connectivity is that its inputs are accompanied by corresponding RCA and XLR line outputs. These allow the incoming signal to be passed onward to additional amplification, making more elaborate installations possible without requiring a separate external signal-distribution device.
One intended application is to partner the power amplifier with the Caspian M2 integrated amplifier in a bi-amped system. Subject to the loudspeakers being designed for separate amplification of their driver sections, one amplifier can power one section while the other handles another. The line outputs also support expansion to tri-amping with additional appropriate amplification and compatible speakers.
This architecture gives the Caspian M2 a useful path from a simpler arrangement to a more complex one. An owner could use it as the sole power amplifier behind a preamplifier or introduce it as an additional power stage in an existing Caspian M2 installation. The availability of both RCA and XLR outputs means the expansion feature is not restricted to a single line-connection format.
System placement and ownership considerations
Despite being only 80 mm high, the Caspian M2 should not be mistaken for a lightweight desktop component. Its 14 kg weight and 432 mm width make it a substantial full-size amplifier that needs suitably supportive furniture. Its restrained facade can help it integrate visually into a dedicated equipment stack, especially alongside other Caspian components.
Power consumption is specified at 330 watts with an 8-ohm load and 550 watts with a 4-ohm load, in addition to the 5-watt standby figure. These ratings are relevant when planning the electrical side of a system and underline that the slim case contains a conventional, relatively substantial power-amplifier supply rather than a miniature amplification platform.
The Caspian M2 is produced at Roksan’s UK factory. For buyers interested in where a component is manufactured, that is a clear and documented part of the amplifier’s identity, alongside the stainless steel construction and deliberately minimal industrial design.
Who the Roksan Caspian M2 is for
The most obvious audience is an owner of the Caspian M2 integrated amplifier who wants to build a compatible bi-amped or tri-amped system. The matching design, duplicated line connections, and pass-through outputs make the power amplifier particularly well suited to that role.
It also makes sense for listeners assembling a separate preamplifier and power-amplifier system. Support for both RCA and XLR inputs broadens the range of potential preamplifier partners, while the rated 85 watts per channel into 8 ohms and 125 watts into 4 ohms cover a useful range of conventional passive-speaker applications.
It is less appropriate for someone seeking a single-box system. There is no volume control, source selection, digital input, network playback, or other integrated functionality documented here, so a preamplifier or suitably equipped integrated amplifier is essential. Owners who do not intend to expand beyond a basic stereo configuration may also have little need for the duplicated line outputs, although those connections do not complicate normal use. The Caspian M2 is therefore best viewed as a focused building block rather than a complete electronics solution.
Conclusion
The Roksan Caspian M2 Power Amplifier combines a low-profile stainless steel enclosure with a substantial 350 VA toroidal power supply, rated outputs of 85 watts per channel into 8 ohms and 125 watts into 4 ohms, and a useful selection of RCA and XLR connections. Its corresponding line outputs are particularly important, allowing additional amplifiers to be incorporated into suitable bi-amped or tri-amped systems. Minimal front-panel controls, channel-specific status LEDs, UK production, and a focused analog design reinforce its role as a dedicated power stage. It is ideally suited to Caspian M2 owners planning system expansion, as well as listeners who want a separate stereo power amplifier with balanced and single-ended connectivity but do not require integrated source or volume controls.
