Quite clear step backwards from K501

The K501 I have a very long time, and after daily use and an incident which my son brings calibration was with scissors the cable back together Solder ;-) began to mechanical problems, yesterday I noticed a very slight loose contact. So I looked around for a worthy successor. You have to know this, that I want to hear music exactly as it was recorded, with maximum transparency. When an artist is breathing something louder, then I want to hear; String and noise and reflections in the room (eg concert hall) are essential for a lively and realistic experience. The K501 gives me all this, though due to the high impedance with a limited volume of my MicroStreamer (otherwise the interaction really like me!).

After reading the specifications and reviews I was expecting from K712pro an increase in skills, so that's at all possible; more transparency, but in any case, more ease and also quite profane more volume. The final point I was not disappointed, the first two, however, were a bitter defeat. What the K501 nice wide spread of instruments in the virtual space and makes as individual audible blurred when K712pro a Klangbreinatürlich there this for less money significantly worse, but in the price range of 400 this performance is just not appropriate. The bass boost 3dB does not sound like much, but unfortunately, makes all non-synthetic sounds for an unnatural Brummelbart. There are probably people who want to listen to their pop music so, but do not buy a pair of headphones with a claim like him AKG reference studio headphones suggests.

All this introduces me to a big problem: if me as a bastion of transparency also allows AKG down, then who built me ​​my next headphones?
