This is already stated in the “Get hose EDU Discount” Thread, but as it isn´t the freshest Thread in the World, I can confirm that you get 50% Discount with the Enrollment Letter.
The only thing you have to be aware, is that the Discount is only working for their digital Products. So if you´re planning to buy their Mic as well, keep that in mind.
I´m more than hapy with the Software! It took my Headphone listening Game to a whole new Level and even the Sound in my (untreated, slope ceiling) Room sounds WAY better than before!
For me round about 150€ very well spent
