what do you think Feanor?
That Anker Pro device is interesting because -- if I understand it's capabilities -- it provides a battery power source for the attached device, (e.g. an SMSL SD-1955). Battery power, in principle, is the lowest noise power source possible. If you get one, definitely let us know how it works out.
