829yn, I have never heard any of the dacs you list and feel that even USB2 is short of SP Dif and certainly short of FW. As Audiojan says only you can make the judgment. Digital is moving ahead so rapidly, that anything you buy today will be obsolete tomorrow.
I am presently using an Exemplar Audio tube dac that is better than my old Weiss Dac202, but soon I will be getting a FW input dac that runs in native DSD. But it really is a pro dac from Empirical Audio Legacy.
