Hi - Would you say that this is a better Dac than the A20H? Help me understand what you mean that the X20 Pro has 4 D/A per channel - I thought it has just two ES9028 chips? Does each channel has it's own independent power supply? Do the chips operate in mono or stereo?

Hi Garth,x20 pro just DAC,A20H is head amp+DAC.X20 PRO DAC better than A20H DAC.X20 PRO have 4 channel, 2 slices ES9028PRO, not independent power supply,it's stereo.ES9028PRO have 8 channels.Thank you.

Do it play over 20khz or its frequency responce is limited by 20khz ?

Hi George,    According to the sampling theorem,the upper limit of frequency is half of the current input digital signal sampling rate,when working in PCM mode.    Thank you.
