I understand your dilemma, and in my own opinion it may be money best spent elsewhere. I have no idea what your current studio setup is (whether, like most have already said, you have a quality room, converters, outboard, etc.), but 10,000 Euros could buy so many wonderful toys/treatments/anything.
The issue with so many pieces of uber-top-end gear is that you are paying thousands more for what often amounts to a miniscule difference. Yes, the tiny differences may add up over multiple track counts. Yes, sometimes that tiny difference is exactly what you need. But whenever a decision like this comes into play, I cannot help but think of the four great compressors I could get for the price of one Elysia. Just an example, but you get the idea.
