I'd be interested in comparisons between the iBasso DC03 Pro and KA11. Also, what is the KA11's default digital filter, given that I'd be stuck with that if I'm using it with my iPhone?
I coulda swore it was set to the slow roll off phase compensated filter when it was new, but when I reset the KA11 settings the minimum phase fast roll off filter is what's showing as the default.
