Excellent high-end concept with neutral sound character

The Caspian 4G Integrated Amplifier was awarded the rarely given "HiFi-IFAs Hammer" by HiFi-IFAs. In the listening test, it impressed with a cleanly centered, three-dimensional soundstage, clear precision, and controlled dynamics, without sounding sterile. The sonic signature remains consistent – regardless of whether music is played analog, digitally via the integrated DAC, or via the integrated MM phono stage.

Consistent dual-mono design for control and power reserves

Inside, a channel-separated dual-mono design is at work: Each channel has its own power amplifier, which operates isolated from the other channel. The power is up to 200 watts (4 ohms) or 105 watts (8 ohms, both channels driven), designed for powerfully controlled loudspeaker operation and tightly guided bass.

Euphoria power amplifiers in Class AB operation

Roksan relies on its own "Euphoria" circuit topology, where power supplies for voltage and current amplification are implemented separately. The power amplifiers are located on the sides of the housing and are cooled via ventilation slots.

Rapture DAC in dual-mono balanced design

The integrated Rapture DAC is also designed in dual-mono. Voltage amplification is not classically done via DAC/OP-Amps, but via a specially developed Current-Conveyor made of passive components. PCM is supported up to 24 bit / 192 kHz (coaxial) or up to 24 bit / 96 kHz (optical).

Integrated and seamlessly tuned MM phono stage

An integrated Moving-Magnet phono stage is also installed. In the listening test, the amplifier's characteristic remains seamlessly preserved even via phono-MM: transparent, neutral, and consistent across all sources.

Design, operation, and finish

The aluminum housing feels premium and weighs 15.2 kg. Visually, bevelled edges and a striking rotary control define the front, flanked by an OLED panel (source pictograms) and a separate volume display. The housing is designed "screwless", access is from the underside; the internal structure is "upside down". Available in silver or black.

Everyday features including app setup

Bluetooth audio is integrated (incl. aptX). Additionally, the amplifier can be configured via the MaestroUnite app (including inputs/outputs, audio settings, firmware updates, DSP functions).

Remote control included
