I would say that the treble I am hearing is pretty accurate to what I would expect, listening the Dire Straits "So Far away", "money for nothing" and "walk of life". These are the tracks I listened to at CanJam with the demo sets and thought the treble was a little tizzy and unnatural.
Thanks for your input.
It's funny you should mention that album, though - I have always considered the treble in that album to have a 'digital-sounding' synthetic 'tizz' sound, regardless of whether played through full size hi-fi with smoothly-detailed silk-dome tweeters, or on portable gear, so perhaps those particular tracks would not be a reliable baseline for judging the treble of the Roxannes.
Maybe try something acoustic, perhaps?
What I meant was that, because of my experience with the UM Miracle, I am not looking to repeat the experience of the treble sometimes lacking delicacy in the micro-details around 8-12khz band. Don't get me wrong, I really like the Miracle in many respects and would still enjoy it if I bought it again. But (IMO) (and as just one example) it does not reproduce the subtle shimmer of brushed cymbals entirely convincingly - there's a kind of 'graininess' sometimes which makes me realise I'm listening to cymbals being reproduced through a transducer, rather than being convincingly fooled that I'm listening to actual cymbals. Whether that's the fault of the BA, the tuning, or some other factor, I can't say for sure, but I definitely heard it on many different occasions, with many different pieces of music (and this was being driven by a DX100, which is known for it's delicacy and transparency with treble).
So I'd love to find a CIEM (perhaps the Roxanne...) which does most of what the Miracle does so well, but adds greater treble realism to the equation. Hence, my question
