I bought the IE800 after having been introduced to them by Dr Axel Grell at last year's London Canjam. I was immediately struck by the soundstage and detail. I then carefully looked at descriptions of the counterfeit versions and went to a reputable dealer (Graham's Hifi in London N1) and bought a set. The tell-tale signs of a fake don't seem to be there (the logo, for example).
My best IEMs before that were the Shure EC4-N (now long-in-the-tooth, but sounding glorious now that I have the Chord Hugo). With the Shures, the midrange is particularly satisfying, the soundstage good if a little approximate, the timbre of instruments etc excellent. Very much the case with the HDTracks version of Strauss's Four Last Songs with Elizabeth Schwarzkopf.
I am listening to the last of the songs. Switching to the IE800, the sound is less refulgent at the beginning. Schwarzkopf enters and the sound is less detailed with less 'contact' with the singer (compared to the Shure). Everything is set back a little. Things improve a lot if a pull the little monitors out of the ear canal so that they are almost falling out. There is a 'sweet spot' where they sound a lot better.
I need advice about third party tips before I decide to move on. All suggestions very gratefully received. I am after the best sound possible, not comfort. I don't use IEMs on the move much. Thank you all in advance.
