Wadia engineers have long believed the best way to process and convert a digital signal is to have the digital to analog conversion be the very last step before delivering the signal to the loudspeaker. Until recently, the circuit technology required to execute this strategy was exceptionally expensive. Working with key manufacturing partners, Wadia developed a unique integrated circuitry solution. Now, Wadia PowerDAC technology delivers performance audibly superior to conventional digital amplifiers. Astonishingly pure resolution and clarity. The Wadia 151PowerDAC mini is a sophisticated combination of high performance DAC, surprisingly robust amplifier, and plenty of inputs for today's digital sources. With a nod to Wadia's original Reference PowerDAC, the 151uses a scaled-down version... Less
