I'm asking myself is it worth the hassle of spending an afternoon in a city centre retailer (with the attendant petrol, hassle of parking this time of year etc etc bah humbug) to see if there is any real value in upgdrading from a DACmagic to either a Rega DAC or maybe the Audiolab - i.e. a £500 DAC? Given how difficult it is to distinguish between the three filter settings on the dacmagic then I am sceptical, but I have an itch that needs scratching...
