The Quad Vena amplifier-DAC is a stereo model capable of delivering up to 2x45 watts into 8 ohms, equipped with a 24-bit/192 kHz compatible audio DAC and an apt-X Bluetooth wireless receiver.
In other words, a highly functional amplifier, designed to appeal to digital music enthusiasts who primarily use their computer or smartphone as an audio source. In conclusion, while the Quad Vena's built-in DAC is quite useful, this amplifier is even more capable when paired with a very good source equipped with an audiophile power supply.

Launched at around 799 euros, sold at half of the original price! Comes with control remote and power cable. No box but will be extremely well packaged.

Would consider posting it internationally but please, ask for a quote as the postage differs from country to country and the amount in the description is for European Union only, thanks. 

Qobuz: "The Quad Vena amplifier is a modern, well-designed, and solidly built device. Equipped with a 24-bit/192kHz USB and S/PDIF DAC and aptX Bluetooth connectivity, it excels at streaming digital music, while its beautifully smooth and refined sound makes it a pleasure to listen to. We have therefore decided to award it our Qobuzissime prize."

We start with a quick blast of Up Is Down from Pirates Of The Caribbean: At World’s End – and a blast is exactly how it feels. It’s quite unlike the traditional Quad character to which we’ve become accustomed.

The track sounds big, bold – even quite boisterous. There’s serious weight and power on show, as wave after wave of orchestral attack crashes down on the listener.

Stream a CD rip of Jay-Z’s Already Home and the Quad shows a superb sense of control. Faced with the meaty, concentrated bassline the Vena keeps a firm grip, offering depth and control in equal measure. The soundstage is wide but all the elements are held firmly in place. Strings sound explicit, the vocal focused and straight to the point.

We play music through the headphone amplifier and we’re pleased to report the Quad’s lively sonic character continues. Faced with Led Zeppelin’s Kashmir, the Vena doesn’t shirk its responsibilities, placing tight, punchy drum thwacks alongside the track’s guitar riff.

Switch to Bluetooth, pair up a smartphone, and even though there is the inevitable drop in quality that the streaming system brings, along with a loss of scale and dynamics compared to a wired connection, you don’t experience the thin, hard quality that often blights the use of Bluetooth.
