err, which contacts? Plugs that are plated shouldn't need cleaning, bare speaker wire will oxidise over time, but rather than clean it, you can cut the end off and re-strip it. To me, adding a linear psu made no difference, although adding a DAC (albeit one quite a bit more expensive than the one you're looking at) made a nice improvement. My experience with DAC's are that the effect is subtle, unlike an amp, or speakers, but over a relaxed listening session, the improvement is very worthwhile. i.e. it is hard to notice a difference with quick AB's, but if you listen to an album with one dac, and then switch to another, the difference becomes much more apparent.
