I've had the 901 for about a year now, sure is sweet
for either the grace 901 or the 902, you could also go S/PDIF out of the VX pocket into the grace. the 902 adds the usb option.
but I'd say the grace DAC is superior to the vx pocket, so going digi into the grace would be better than balanced XLR.
Very sweet. But a lot more $ then the amp u listed
yes, but if you're looking into the addition of a DAC anyway, the grace units are certainly something to consider.
