In the "old days" the EU ps 220V was crappier than the ps used by US people, all logitech branded SB3 comes with a better supply, my old supply works but its smells "hot" even if it works properly... Btw my Meridian gear which can be considered high end is filled with switch mode psu's so the technology is not inherently bad, just the usual audiophile fud/conservatism that always hamper real development of high end audio.
