Thanks for the long reply's, I appreciate it, spatially the long ones, makes more understandable all this, that I could solve doing a test, or a demo, but I started the hobby 2 months before corona, and before that my life was less boring that I am willing to spend now 1000€ in a headphones instead of holydays or travelling or visiting the family or... hehe... anyhow.
Everything is relative of course. Of course, and I know the difference between detailed driver and the highs not rolling off and appearing as detailed. I do know that, non audiophile but sound and music lover for few decades now almost...
The thing is this, i have sennheiser hd6XX and I have sennheiser hd25. HD 6XX I call it detailed, HD25 I call them not detailed, at all, but hey, for 99€ and for the ipod, more than good enough, for outdoors, for putting them on abag and not breaking, marvelous, sound signature, even more marvelous, detail; amazing for 99€. Now, if I spend 900€ and I get the same detail level than the HD25, I may return them the very same day, and order LCD X. So because everything is relative, and since I haven't tested them, detail needs to be kind of rated, as well as any other of the sound specs. You do not get out of my pocket 1000$ so easily. I mean, I´m deeply stupid, good, ok, but so so stupid, no my dear, no. Now, when you say, when I put those lcd2 in my head I am going to crap on my pants pretty much, that's what some people said, that is what I need confirmation about. Lot of people say that hd6XX or sundara have better detail retrieval than 2C, although maybe it is actually the sound signature of those with the highs rolled of. HD6XX has highs rolled off a bit to, but they sund detailed, they can retrieve the detail, with them it's easier to notice, sound quality, sampling rate. With non detailed headphones, sounds the same a high quality mp3 against a red book or a DSD/real high res stuff.
Anyhow, 610€ shipped gets me an LCD-2C new "b-stock", returned and vat free. 990€ shipped gets me an LCD-X. Hard to decide. The third candidate DT770 80 Ohm, the other was the Neumann 500€ closed cans, I already removed that candidate.
Amp will be the SIngxer SA1.
About the DT1770, after so much people telling me that is pure crap, without wanting to tell me that they are crap, I give up on them.
