There is not a step but a whole world between my MS1000's and the Magnumized setup. To put it mildly. I guess it is just the superiority of the drivers, which quite many people consider superior to Grado RS1 or MS Pro drivers. And now the really fine aspect: You can buy those drivers separately, at a truly more than fair price of $120 a pair. Just check out the feedback on those drivers on Head-Fi. As you know we EU-based guys have to add shipping and customs. Shipping to Austria was $25 and customs added another €25. My second package of Magnum drivers came without any customs fees. Was lucky this time. I paid about €190 for 2 sets of V4 drivers. Incredible price/performance ratio if you consider the price of stock Gradessandros in Europe. I paid as much for my first stock plastic SR80i!!
