"What is the "Magico Concept"
No holds barred build quality and associated cost is what I see.
You would have to be crazy to spend that kind of money based on others impressions. All that matters is how something sounds to you or even just whetehr you like it or not for whatever reason. The build quality alone regardless of sound is a selling point.
Personally, the Magico's I have heard have been top notch sounding. The value proposition is a tougher call. But love is a tricky thing. You'd best really love anything at those prices before shelling out the bucks, unless of course if money just does not matter.
Let's face it, gear in these price categories are luxuries that only a select few will ever justify owning. The good news for mere mortals like myself is I believe you can do equally well for a lot less if you are smart about it.
