Blue Aura V40


A brilliant, affordable entry to the world of valves.

With built in Bluetooth streaming, two analogue inputs, USB/Dac input! and subwoofer out.

We were sceptical until we listened. Wow. Super smooth presentation, punchy and with great dynamics.

Great with small monitors like AVI Neutrons.

Come have a listen.
