The LittleDot MK3+ has two versions: with Bluetooth wireless input or not. It's combined framework keeps advantages form both tube and transistor. Especially it performs excellently when driving low resistance headphones. Built-in Bluetooth 4.2 (Bluetooth version only) Oxidation treated surface and golden plated tube guard board.








MK3+ used a combined framework. The tube front stage presents sweet sound performance and transistor back stage supports high drive power. This framework guaranteed both high-current to drive low resistance headphones and high voltage swing for high resistance headphones.
The tube parts of MK3+ is set up with a pair of 6C4 tubes.Transistor parts is a PNP/NPN discrete symmetrical Class-A amplifier circuit.
