Thanks for the words of hope and encouragement and I am really hoping that the burn-in will make the difference. Of course everyone has different frames of reference so I would like to ask a favor of you to give me some perspective.
One of my favorite test tracks for high-end response is Pink Floyd's Happiest Days of Our Lives (The Wall). There is a 16th time hi-hat cymbal in that track starting at about 0.39. On all 3 my main audio systems (high-end, home theater and desktop) as well as my HD650 and also from memory, my UE 10 Pro, that cymbal is fairly prominent. On the Roxannes it is not prominent at all. The first few 5 beat salvos are there but veiled. After that, the constant cymbal is very indistinct. If I did not listen for it I would almost not notice it. Even the vocals sound like they are behind The Wall :). So for me it is not that the Roxannes are merely laid-back vs. my personal preferences. I feel the Roxannes are completely almost hiding some detail.
Would you possibly be able to do a comparison of that track on your different headphones etc. and let me know your impressions? If you hear it distinctly and prominently and consider them as detailed as your HD 800 then I will have some hope and will explore with you further about DAP/Dac/Amp pairings etc. and hold out for burn in. Thanks again.
