So it is with DC Elite \u2013 virtually a miniature DX320 Max TI.<\/p>\n It goes right onto Headfonia<\/a>‘s Recommended Buys list. Headfonics<\/a> adds “it’s a monster of a dongle DAC” and\u00a0Twister6<\/a> adds iBasso stepped it up with DC Elite. “iBasso’s DC Elite redefines what\u2019s possible from a portable DAC\/Amp dongle” says MOONSTAR Reviews<\/a>.<\/p>\n DX320 Max TI was groundbreaking because it brought a discrete stepped resistor analog volume control to the fold. So how then should Head-Fi react to DC Elite packing exactly the same ridiculous marvel of engineering, in dongle DAC\/amp size?<\/p>\n DC Elite’s\u00a0stepped volume attenuator, developed in-house from individual resistors by iBasso, is where the money is at. It’s that that enables it to play it delicately into your flagship earphones for enjoyment at realistically lower volume levels.<\/p>\n Together with the resolution of ROHM’s BD34301EKV DAC operating in full current-output mode,\u00a0DC Elite is the zenith of mini USB DAC\/amp development.
