The Roksan Caspian 4G Streaming Integrated Amplifier is an all-in-one amplifier that combines 105 watts of Class-AB power with the Rapture DAC, HDMI eARC and the BluOS streaming platform.
The power of the Caspian line meets modern connectivity: a classic sports-car engine with the most modern infotainment. For anyone who wants an uncompromising one-box system that takes the TV along too.
Why the Caspian 4G Streaming Integrated Amplifier?
Here sits the award-winning Caspian power stage – 105 watts at 8 ohms, 200 watts at 4 ohms in Class-AB – in the same chassis as a full-fledged streamer. The in-house Rapture DAC converts up to 24-bit/192 kHz, BluOS and AirPlay 2 deliver streaming and multiroom, and an HDMI eARC input brings the TV on board – you then control volume with the TV remote. StereoNET awarded the model its Applause Award in October 2024.
What you hear
The Caspian 4G Streaming drives speakers with a precision you'd otherwise expect from separate pre/power amp combinations. Bass arrives with authority and contour, vocals and fine dynamics stay clearly drawn even at high levels. Digital and analog alike, it plays calm, spacious and stable – a single box that replaces an entire component chain without losing sonic ground.
Who is the Caspian 4G Streaming right for?
Ideal for you if you want a high-quality all-in-one solution that bundles streaming, TV sound and vinyl in a single unit and confidently drives large speakers too. Good to know: streaming services are an option, not a must – internet radio, NAS and local files run without a subscription. Straight talk: if you only run small bookshelf speakers at room volume, the Attessa Streaming serves you more affordably. And the massive chassis needs a sturdy rack with clearance above it.
Our verdict
Here at our Wädenswil store, the Caspian 4G Streaming is our recommendation for anyone looking for a genuine one-box solution without making sonic compromises. High-end power and modern control under one lid.

Frequently asked questions
Does the Caspian 4G Streaming have an HDMI connection for the TV?
Yes, an HDMI eARC input. You connect the TV directly, enjoy its sound in stereo quality and adjust volume conveniently with the TV remote. This turns the amplifier into a powerful-sounding base for film and music.
Is the amplifier compatible with AirPlay 2 and multiroom?
Yes. It supports Apple AirPlay 2 and is based on BluOS, so it can be linked with other BluOS devices from Bluesound, NAD or Roksan into a multiroom system. You send music directly from your usual apps.
Do I need a paid streaming subscription?
No. The Caspian plays internet radio, music from a NAS and local files without a subscription. You can add services like Tidal, Qobuz or Spotify as you wish. That way you decide how much streaming you use.
Can I connect a turntable?
Yes, an MM phono stage is built in. You connect turntables with a moving-magnet cartridge directly, with no external preamp. For MC cartridges you need an additional module. XLR and RCA inputs let you add further sources.
