About the Roksan Caspian 4G Dual-Monoblock System (Pre + 2 Power)
Running power amplifiers as mono blocks gives each channel its own circuitry and power supply, which all but removes crosstalk and gives far more headroom and control over demanding speakers. Roksan call it the pinnacle of Caspian performance.
Each mono block can sit close to its speaker, for shorter speaker cables. The streaming pre-amp is the What Hi-Fi? Awards 2026-winning Caspian 4G, with BluOS, a phono stage for MM and MC cartridges and HDMI eARC.
Genuine UK stock from an authorised Roksan dealer, with the full five-year Roksan warranty. Want it set up properly? We install hi-fi, streaming and multi-room audio across the New Forest and the south coast. See our audio and video work.

Questions about the Roksan Caspian 4G Dual-Monoblock System (Pre + 2 Power)
Is this cheaper than buying the three separately?
It’s the same price as the pre-amp (£3,500) and two power amps (£3,000 each) bought separately, just in one matching order.
Do I need anything else?
Speakers, speaker cable, and balanced XLR interconnects from the pre-amp to each mono block. Ask us and we’ll match them to your system.
Why mono blocks?
Each speaker gets its own amplifier and power supply, so there’s more power, more headroom and almost no crosstalk between channels.
