Me too... I don´t know why I haven´t went through the entire thread before just read the review. As for Ed 9 well I have the cheap made in taiwan ED 9 PRO 900. As for bass yes it extends quite a bit further then the DX 1000 and it´s audible for my ears... Where the DX 1000 just go out with a bang the PRO 900 continues down and with melody where the DX 1000 just outputs the same note. Maybe there is some bass hump that just drown the lower frequencies? You can just about hint them often though but sometimes you really need to hear the 900 first to be sure.
Which one that has better bass really depends on the the song. I really like that the DX 1000 is never ever vibrating and it has a very nice tone with bass guitars and such. PRO 900 being more detailed and goes deeper but the DX 1000 somehow have more expensive bass so to speak and for most music enough extension
Have a hard time figuring out what I like more. I was once dead certain that the DX 1000 was my classical, jazz headphone but as of late I don´t know any longer. It has so much power it made my KeeS modded my PRO 900 it just sounded to bright and thin lacking body so back at stock now without cotton wool. DX 1000 still having more impact so to speak while still being quite smooth.. 900 have significantly more bass then the 750 but not as much as the HD 650/DX 1000. At least it appears that way may just be the treble which gets more space on the 900 with better extension that make it appear less bassy for classical. Larger soundstage than the 750 so more laid back and less forward in stock anyway. Even the DX 1000 seems slightly more forward as well. PRO 900 actually competes with the DX 1000 in size of the soundstage. It´s still not as big as the K701 but it´s deeper than the DX 1000 but maybe not quite as wide with better separation between instruments and more out of head experiences then the DX 1000 gives me. More noticable in movies then music though. Soundstage is really something both excels at.
However as of late it all seems to melt together and sound more and more the same. PRO 900 not appearing that weak anymore and the DX 1000 not having all the fanfare I remember. Maybe my ears are getting numb after to much listening or I am just getting to used to the DX 1000. It´s to the point I don´t know which headphone are on my head any longer I find myself feeling if it´s wooden cups or not
. So comfort is absolutely a non issue for both. I loved the leather feel of the DX 1000 but now I am taking that for granted too
PRO 900 seem to have a more even response and is overall brighter. It still does feel like it has less power then the DX 1000. DX 1000 sounds more expensive really it´s sound signature matches it´s appearance perfectly. I guess it´s something with the colouration from the wood that does that and the fact it does always sound solid and give a wholehearted performance
. Can be hurtful at times though but not often. Sometimes with piano the DX 1000 puts your head inside the piano and let someone hammer on the tangent to give you a tinnitus tone. Not often though. Have quite a kick not just in bass but overall so seem to move more air then the PRO 900 at the same SPL levels.
Otherwise it does bass guitars great and most real instruments with power. Piano as mentioned it does okay about on par with K701 but not as good as the PRO 900.
