Your best bet is to visit a dealer who has both. I am a former mkII owner, and I upgraded to a used VT200 at a bargain price, restocked the input/drivers with Amperex, and have found the improvement to be substantial. It's not at all about 3db extra spl. It's about more refined, effortless delivery. The VT200 comes with much better caps -Wondercaps, better power supply, etc.
