Quad Vena II Integrated Amplifier
Building on the strengths of its predecessor, the Vena II is an exceptionally neat and convenient way to bring true high-fidelity sound to the varied nature of modern music collections – from vinyl and CD to digital streaming and hi-res files – via all manner of playback devices.

SMART AESTHETICS
The Vena II’s small footprint (compared to many amps in its class) allows flexible positioning and ensures the amp slips tidily into a range of environments. The amp‘s dapper design is enhanced by a choice of four finishes: Quad’s classic Lancaster Grey is the standard option, while three Deluxe finishes – Sapele Mahogany, Gloss Black and Gloss White – wrap the Vena II’s aluminium housing in veneered or lacquered wood.
SIGNIFICANT IMPROVEMENTS
The Class AB power amp section now has an upgraded power supply, a new 200VA toroidal transformer lying at its heart. This is followed by 2x15000uF reservoir capacity (30000uF in total), helping the amp to maintain firm control of the music whilst enabling excellent dynamic range.
Vinyl lovers will appreciate the addition of a phono stage for moving magnet cartridges – a high-quality, low-noise, JFET-based circuit with precise RIAA equalisation.
Headphone users are also better catered for. The original Vena included a headphone output, but this was connected to the amp’s main output stage rather than to a specialised headphone amp circuit. The Vena II incorporates a dedicated headphone amp with current-feedback circuitry, its gain bandwidth and high slew rate delivering a more dynamic, detailed and engaging performance with all manner of headphone types.
Simplicity is key to the Vena II’s outward design. Quad’s design team selected Bluetooth wireless streaming, with support for the aptX codec, to ensure easy pairing with all manner of smartphones, tablets, PCs and Macs – expertly implemented to deliver an adroit balance of quality and convenience. The Vena II feels like a traditional hi-fi amplifier, with its uncomplicated front-mounted controls and simple remote, yet its specification is state-of-the-art.
Copious cable connections enhance the amp’s flexibility. Inputs for digital sources comprise asynchronous USB and three S/PDIF sockets (one coaxial and two optical), while digital outputs are provided in optical and coaxial flavours. Analogue signals are catered for by three stereo RCA inputs – two line-level plus the new MM phono input for turntables – while pre-out sockets permit the addition of an external power amplifier.
