Thx for asking! Just love how considerate and helpful fellow headfiers are. No one has yet rejected my pms and always provided with really useful information. I have found numerous headphones all with similar sound signature but different price range.
At the lowest price range, m100, then hd650 then LCD-2 and then the th-900. If you can see the trend, all 4 hps have a slightly Bassy, warm and neutral-slightly bright sound sig and def. no analytical sound! I have stopped my search for a while just reading the forums here am there, for some personal reasons. Looking into CIEMs and amp/dacs because my hps are more less settled. Because CIEMs seem interesting.
CIEMs are also somewhat different. The only caution I have for you about CIEMs is resale value is poor cos the shell has to be destroyed for the next buyer. And most hybrid CIEMs can't be re-sold altogether as the DD is glued to the shell (do destroying the shell means destroying the DD too & only the BAs are reusable). But if you never sell the CIEM, then this won't be an issue at all.
