Well the superdacs just arrived at home and I've got a week of work :) The bad news :- I can't play with it because I haven't got a coaxial ic or adaptors for the jacks, and the hifi shops round here all have the very quaint custom of being closed on mondays, doh! So it looks like I'll have to pop in to Movement tomorrow to pick up either an ixos or qed coaxial. Can't wait. This will be my first upgrade since buying the missions about a year or two ago. Cheers. EDITED TO ADD:- Just been looking at the power supply and didnt realise the 9v power pack would be two pronged us style. I have one of those adaptor plugs that have "for shavers only" on them that let you plug two pronged and then plug them into the wallsocket. Would that be safe to use for the time being or would I be better of getting someone to build me a dedicated psu? I also have a musical fidelity xpsu, is it possible to use that instead or would I just fry the dac and possibly the house electricals as well?
