The VMV VA2 offers a no frills design, with 1/4" outputs and a volume knob on the front, and a power switch, plug and RCA inputs to connect to your DAC on the back. The low impedance output pairs exceedingly well with IEMs, giving you a black background without hiss or noise. Count on the high impedance output to drive higher impedance headphones like the HD 600 with authority. Finished with a CNC machined solid aluminum chassis, the VMV VA2 offers a price-to-value point that's hard to beat.
