Thank you

That's most informative. Given that, can I digress to the equivalents in open back, IE the Shure SRH1840 and beyerdynamic DT1990pro ? Have you compared those two, and compared them in the context of being vs their closed back counterparts ? At the moment I'm leaning towards the Shure closed back as isolation is not an issue to me, The only difference is that I think I probably prefer mid bass to sub bass. Which of those two would represent the drums say (not the big bass drums), in Phil Collins "In the air tonight" or Dire straits drum solos etc ? Just asking that so I can clarify what bass I'm talking about, LOL. Isolation is the least important issue to me. My main appreciation is for crisp, accurate, precise detail. Specific treble, not muddy, excellent mids (I listen to a lot of instrumental but probably more music with voice) and capable but not overly "thumpy" bass. IE I'm not keen on the "doof doof doof" bass that you hear as a boy racer drives past you. I like the lower frequencies but I like them to be defined. (Hark at me starting to use terminology; I can only hope its correct, hahah).
