I tried out the tape mod again tonight .... and I have to say it's good. Not sure why I didn't like it the first time but now I have found that it tightens everything up not just the bass. I like :)
After a lot of fiddling with my IE800, I think I have got the best sound out of them at last. I had to hack it with an extended tube so I can put a bi-flange tip on it to made it sound the best.
Non of it's stock tips fit .. it's either large soundstage, clarity, no bass with small tips .. or all bass and nothing else with large tips. It's such a dumb idea for them to make proprietary tips.
Stock tips also gave me vocals that sound so far away. This mod has made the lower mids and vocals pop out a lot more.
At the moment the H3 stands toe to toe with the ie800 in every way but I think the H3 does much better mids .. it's got lushness and smoothness in female vocals that the ie800 doesn't have. And this is without having to fiddle with fit and tips. I think even my ATH-IM70 and Heaven IV have a special quality to them that make me want to keep them ... both being vocal specialist in their own special way.
I'm not sure where the ie800 fits in for me as my other way cheaper iems does just as well and really hasn't given me that 'wow' moment yet.
