With JJ Electronics European-produced valves, the V40 Blackline is claimed to provide the warm, luxurious sound that’s so commonly associated with tube amplifiers. Output is quoted as 30W with an impedance of 4 or 8ohm, and the V40 is the first product in the Blackline range to offer Bluetooth 4.0 connectivity – aptX no less. Additional socketry includes RCA phono inputs and a micro USB port. With a piano black finish, the V40 Blackline is available to buy now for £449. Meanwhile Blue Aura founder, Nick Holland, tells us that the company will be launching sonically matching loudspeakers to accompany the V40 amplifier “towards the end of April”.
