This really is the problem isn't it? We all can prefer "non-flat" at times, on certain recordings, etc. etc. Makes us the Sound Engineer!! What fun. But then it's not really "Hi-Fidelity reproduction" anymore is it? Not when we insert ourselves and our personal preferences into the mix.Over the long haul, I have always prefered flat. Its the only thing that I don't get tired of. And here I mean measured "flat" - direct sound and reverberant sound, axial response and power response.
