Those looking for extreme high-end audio quality turn to DACs and audio amplifiers, even when it comes to headphones. ASUS has now launched a new Xonar product – the Essence One, which is a USB capable DAC (digital-to-analog convertor) that supports sample rates upto 192kHz. Using up scaling, ASUS claims that this can go right up to 384 kHz. The Xonar Essence One is said to to able to drive headphones with impedance going to up as high as 600 Ohms. The op-amps being used on the Xonar Essence One can also be interchanged, which should help in changing the characteristics of the headphones connected to it.

A 6.3mm to 3.5mm convertor is also bundled with the DAC. ASUS has priced the Essence One at Rs. 21,000 and the product is being sold locally with a warranty of one year.
