Personally, I wouldn't use the mega watt for finish charging. Not that it's not a great little unit, apparently, but it is, after all rated at 13.8v (a conservative rating obviously).
Like mena661 said, the mean wells go higher; up to 16.5-18v, if I recall. From what I've learned on this forum recently, you need something with high voltage, low amps for finishing. And seeing as high voltages come relatively cheap compared to high amps, there are much better alternatives to the mega watt, for finishing and eq'ing, IMO.
Not that my choice is the best, but I went with a variable adjustable unit; not cheap, but very versatile... and it satisfies my tendencies towards being a bit of a control freak :).
That said, the mega watt makes for a great boost/abs charger, provided the 30-36 amps are sufficient.
