Benchmark Dac 1 USB

Dear all,
ive been looking into DACS recently and i come accross this one while browsing the net. It is not very expensive relativly speaking. its small light weight and not very visually striking . there are very glowing reviews on the net. even suggestions that only the very, very best can better its performance.i find that quite difficult to believe. i dont take reviewers word for it, but they are able to point in a right direction. I would like to hear from owners of this dac. how would this dac compare to a dac in a 3-4k player? is it really only bettered by very expensive dacs? any views? thank you kindly
